Installation

This package can be installed with the go get command:

go get github.com/mattn/go-sqlite3

go-sqlite3 is cgo package. If you want to build your app using go-sqlite3, you need gcc. However, after you have built and installed go-sqlite3 with go install github.com/mattn/go-sqlite3 (which requires gcc), you can build your app without relying on gcc in future.

Important: because this is a CGO enabled package you are required to set the environment variable CGO_ENABLED=1 and have a gcc compile present within your path.

API Reference

API documentation can be found here: http://godoc.org/github.com/mattn/go-sqlite3

Examples can be found under the examples directory

Connection String

When creating a new SQLite database or connection to an existing one, with the file name additional options can be given. This is also known as a DSN string. (Data Source Name).

Options are append after the filename of the SQLite database. The database filename and options are seperated by an ? (Question Mark). Options should be URL-encoded (see url.QueryEscape).

This also applies when using an in-memory database instead of a file.

Options can be given using the following format: KEYWORD=VALUE and multiple options can be combined with the & ampersand.

This library supports dsn options of SQLite itself and provides additional options.

Boolean values can be one of:

0 no false off
1 yes true on

Features

This package allows additional configuration of features available within SQLite3 to be enabled or disabled by golang build constraints also known as build tags.

Click here for more information about build tags / constraints.

Usage

If you wish to build this library with additional extensions / features. Use the following command.

go build --tags "<FEATURE>"

For available features see the extension list. When using multiple build tags, all the different tags should be space delimted.

Example:

go build --tags "icu json1 fts5 secure_delete"

Feature / Extension List

Extension	Build Tag	Description
Additional Statistics	sqlite_stat4	This option adds additional logic to the ANALYZE command and to the query planner that can help SQLite to chose a better query plan under certain situations. The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlite_stat4 table. The query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications. SQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index. The SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used
Allow URI Authority	sqlite_allow_uri_authority	URI filenames normally throws an error if the authority section is not either empty or "localhost". However, if SQLite is compiled with the SQLITE_ALLOW_URI_AUTHORITY compile-time option, then the URI is converted into a Uniform Naming Convention (UNC) filename and passed down to the underlying operating system that way
App Armor	sqlite_app_armor	When defined, this C-preprocessor macro activates extra code that attempts to detect misuse of the SQLite API, such as passing in NULL pointers to required parameters or using objects after they have been destroyed. App Armor is not available under `Windows`.
Disable Load Extensions	sqlite_omit_load_extension	Loading of external extensions is enabled by default. To disable extension loading add the build tag `sqlite_omit_load_extension`.
Foreign Keys	sqlite_foreign_keys	This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections. Each database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma. Enforcement of foreign key constraints is normally off by default, but if this compile-time parameter is set to 1, enforcement of foreign key constraints will be on by default
Full Auto Vacuum	sqlite_vacuum_full	Set the default auto vacuum to full
Incremental Auto Vacuum	sqlite_vacuum_incr	Set the default auto vacuum to incremental
Full Text Search Engine	sqlite_fts5	When this option is defined in the amalgamation, versions 5 of the full-text search engine (fts5) is added to the build automatically
International Components for Unicode	sqlite_icu	This option causes the International Components for Unicode or "ICU" extension to SQLite to be added to the build
Introspect PRAGMAS	sqlite_introspect	This option adds some extra PRAGMA statements. PRAGMA function_list PRAGMA module_list PRAGMA pragma_list
JSON SQL Functions	sqlite_json	When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically
Pre Update Hook	sqlite_preupdate_hook	Registers a callback function that is invoked prior to each INSERT, UPDATE, and DELETE operation on a database table.
Secure Delete	sqlite_secure_delete	This compile-time option changes the default setting of the secure_delete pragma. When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on. The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur. On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted. See the documentation on the secure_delete pragma for additional information
Secure Delete (FAST)	sqlite_secure_delete_fast	For more information see PRAGMA secure_delete
Tracing / Debug	sqlite_trace	Activate trace functions
User Authentication	sqlite_userauth	SQLite User Authentication see User Authentication for more information.

Compilation

This package requires CGO_ENABLED=1 ennvironment variable if not set by default, and the presence of the gcc compiler.

If you need to add additional CFLAGS or LDFLAGS to the build command, and do not want to modify this package. Then this can be achieved by using the CGO_CFLAGS and CGO_LDFLAGS environment variables.

Android

This package can be compiled for android. Compile with:

go build --tags "android"

For more information see #201

ARM

To compile for ARM use the following environment.

env CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ \
    CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7 \
    go build -v

Additional information:

Cross Compile

This library can be cross-compiled.

In some cases you are required to the CC environment variable with the cross compiler.

Cross Compiling from MAC OSX

The simplest way to cross compile from OSX is to use xgo.

Steps:

Install xgo (go get github.com/karalabe/xgo).
Ensure that your project is within your GOPATH.
Run xgo local/path/to/project.

Please refer to the project's README for further information.

Google Cloud Platform

Building on GCP is not possible because Google Cloud Platform does not allow gcc to be executed.

Please work only with compiled final binaries.

Linux

To compile this package on Linux you must install the development tools for your linux distribution.

To compile under linux use the build tag linux.

go build --tags "linux"

If you wish to link directly to libsqlite3 then you can use the libsqlite3 build tag.

go build --tags "libsqlite3 linux"

When building in an alpine container run the following command before building.

apk add --update gcc musl-dev

Fedora

sudo yum groupinstall "Development Tools" "Development Libraries"

Ubuntu

sudo apt-get install build-essential

Mac OSX

OSX should have all the tools present to compile this package, if not install XCode this will add all the developers tools.

Required dependency

brew install sqlite3

For OSX there is an additional package install which is required if you wish to build the icu extension.

This additional package can be installed with homebrew.

brew upgrade icu4c

To compile for Mac OSX.

go build --tags "darwin"

If you wish to link directly to libsqlite3 then you can use the libsqlite3 build tag.

go build --tags "libsqlite3 darwin"

Additional information:

#206
#404

Windows

To compile this package on Windows OS you must have the gcc compiler installed.

Install a Windows gcc toolchain.
Add the bin folders to the Windows path if the installer did not do this by default.
Open a terminal for the TDM-GCC toolchain, can be found in the Windows Start menu.
Navigate to your project folder and run the go build ... command for this package.

For example the TDM-GCC Toolchain can be found here.

Errors

Compile error: can not be used when making a shared object; recompile with -fPIC

When receiving a compile time error referencing recompile with -FPIC then you are probably using a hardend system.

You can compile the library on a hardend system with the following command.
```
go build -ldflags '-extldflags=-fno-PIC'
```
More details see #120
Can't build go-sqlite3 on windows 64bit.

Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit. See: #27
go get github.com/mattn/go-sqlite3 throws compilation error.

gcc throws: internal compiler error

Remove the download repository from your disk and try re-install with:
```
go install github.com/mattn/go-sqlite3
```

User Authentication

This package supports the SQLite User Authentication module.

Compile

To use the User authentication module the package has to be compiled with the tag sqlite_userauth. See Features.

Usage

Create protected database

To create a database protected by user authentication provide the following argument to the connection string _auth. This will enable user authentication within the database. This option however requires two additional arguments:

_auth_user
_auth_pass

When _auth is present on the connection string user authentication will be enabled and the provided user will be created as an admin user. After initial creation, the parameter _auth has no effect anymore and can be omitted from the connection string.

Example connection string:

Create an user authentication database with user admin and password admin.

file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin

Create an user authentication database with user admin and password admin and use SHA1 for the password encoding.

file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin&_auth_crypt=sha1

Password Encoding

The passwords within the user authentication module of SQLite are encoded with the SQLite function sqlite_cryp. This function uses a ceasar-cypher which is quite insecure. This library provides several additional password encoders which can be configured through the connection string.

The password cypher can be configured with the key _auth_crypt. And if the configured password encoder also requires an salt this can be configured with _auth_salt.

Available Encoders

SHA1
SSHA1 (Salted SHA1)
SHA256
SSHA256 (salted SHA256)
SHA384
SSHA384 (salted SHA384)
SHA512
SSHA512 (salted SHA512)

Restrictions

Operations on the database regarding to user management can only be preformed by an administrator user.

Support

The user authentication supports two kinds of users

administrators
regular users

User Management

User management can be done by directly using the *SQLiteConn or by SQL.

SQL

The following sql functions are available for user management.

Function	Arguments	Description
`authenticate`	username `string`, password `string`	Will authenticate an user, this is done by the connection; and should not be used manually.
`auth_user_add`	username `string`, password `string`, admin `int`	This function will add an user to the database. if the database is not protected by user authentication it will enable it. Argument `admin` is an integer identifying if the added user should be an administrator. Only Administrators can add administrators.
`auth_user_change`	username `string`, password `string`, admin `int`	Function to modify an user. Users can change their own password, but only an administrator can change the administrator flag.
`authUserDelete`	username `string`	Delete an user from the database. Can only be used by an administrator. The current logged in administrator cannot be deleted. This is to make sure their is always an administrator remaining.

These functions will return an integer.

0 (SQLITE_OK)
23 (SQLITE_AUTH) Failed to perform due to authentication or insufficient privileges

Examples

// Autheticate user
// Create Admin User
SELECT auth_user_add('admin2', 'admin2', 1);

// Change password for user
SELECT auth_user_change('user', 'userpassword', 0);

// Delete user
SELECT user_delete('user');

*SQLiteConn

The following functions are available for User authentication from the *SQLiteConn.

Function	Description
`Authenticate(username, password string) error`	Authenticate user
`AuthUserAdd(username, password string, admin bool) error`	Add user
`AuthUserChange(username, password string, admin bool) error`	Modify user
`AuthUserDelete(username string) error`	Delete user

Attached database

When using attached databases. SQLite will use the authentication from the main database for the attached database(s).

Extensions

If you want your own extension to be listed here or you want to add a reference to an extension; please submit an Issue for this.

Spatialite

Spatialite is available as an extension to SQLite, and can be used in combination with this repository. For an example see shaxbee/go-spatialite.

extension-functions.c from SQLite3 Contrib

FAQ

Getting insert error while query is opened.

You can pass some arguments into the connection string, for example, a URI. See: #39
Do you want to cross compile? mingw on Linux or Mac?

See: #106 See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html
Want to get time.Time with current locale

Use _loc=auto in SQLite3 filename schema like file:foo.db?_loc=auto.
Can I use this in multiple routines concurrently?

Yes for readonly. But, No for writable. See #50, #51, #209, #274.
Why I'm getting no such table error?

Why is it racy if I use a sql.Open("sqlite3", ":memory:") database?

Each connection to ":memory:" opens a brand new in-memory sql database, so if the stdlib's sql engine happens to open another connection and you've only specified ":memory:", that connection will see a brand new database. A workaround is to use "file::memory:?cache=shared" (or "file:foobar?mode=memory&cache=shared"). Every connection to this string will point to the same in-memory database.

Note that if the last database connection in the pool closes, the in-memory database is deleted. Make sure the max idle connection limit is > 0, and the connection lifetime is infinite.

For more information see
Reading from database with large amount of goroutines fails on OSX.

OS X limits OS-wide to not have more than 1000 files open simultaneously by default.

For more information see #289
Trying to execute a . (dot) command throws an error.

Error: Error: near ".": syntax error Dot command are part of SQLite3 CLI not of this library.

You need to implement the feature or call the sqlite3 cli.

More information see #305
Error: database is locked

When you get a database is locked. Please use the following options.

Add to DSN: cache=shared

Example:
```
db, err := sql.Open("sqlite3", "file:locked.sqlite?cache=shared")
```
Second please set the database connections of the SQL package to 1.
```
db.SetMaxOpenConns(1)
```

Works with 64-bit Windows (without pkg-config) but doesn't work with 32-bit Windows.

Hello. I've been having trouble with getting this to work on Windows using 32-bit and then found that it works on 64-bit Windows even without pkg-config (which incidentally I had got installed though I'm not sure that could help after all). Having learned more about the current head revision I understand that it works without pkg-config on Windows however I could not get it to work with 32-bit Windows and I get a stream of error messages like "__divdi3: not defined". My understanding of C and cgo is patchy and I'm not sure what this means. I couldn't see why it should be different on 32-bit Windows but perhaps some other compiler option is required.

I resolved my problems by discarding pkg-config and the static compilation on Windows and use the DLL instead, which is what other platforms are using anyway. So instead of the #cgo pkg-config line I'm using "#cgo LDFLAGS: -lsqlite3" having the environment set up with the include files on the path for gcc (LIBRARY_PATH and C_INCLUDE_PATH). The little work with cgo that I've done so far this works best with the smallest of changes to the source-code across platforms.

I've never used pkg-config before and while I had no trouble with it on other platforms on Windows it was a struggle getting an environment set up. Wouldn't this be better without pkg-config?

In any case the current head revision doesn't appear to work for 32-bit Windows and the static compilation as an exception for Windows seems unnecessarily complicated. Maybe you can get it to work but I wonder if this is the wrong direction to go.

Install without gcc (not possible)

Is it possible to use the library in Go without recompiling the binaries?https://github.com/lxc/lxd/issues/762#issuecomment-112463214

I mean is it possible to compile binary pieces of SQLite needed be go-sqlite3 and ship them in separate repository, so that only Go itself can be used to assemble the final product together? Maybe Go already provides some helpers/tools to do that?
Problem with unstable go-sqlite3 version - 2.0.3

Hi,

We at the platform team of razorpay internally use bulk-insert which internally uses github.com/jinzhu/gorm v1.9.12 and creates an indirect dependency on github.com/mattn/go-sqlite3 v2.0.3.

Reference :- https://github.com/t-tiger/gorm-bulk-insert/blob/master/go.mod#L14

Now, this setup was working fine for us till last week and suddenly we had a failure in our docker build for github actions citing github.com/mattn/[email protected]+incompatible: unknown revision v2.0.3

We also saw one of your issues where you mentioned versions 2.0+ were unstable - issue

Did you stop supporting 2.0.3 version suddenly in the last 7-10 days. We were wondering what caused the breakage of the build from our side. It would be helpful if you could throw some light on this issue.

Thanks, Shriram

Cross compiling fails

Very possibly a mistake on my part, if so please let me know where I went wrong. My first time with Go today!

I have a basic Go file using this library. I am on macOS 10.12.3, Go 1.8 darwin/amd64.

Succeeds: env GOOS=darwin go build -i app.go

Fails: env GOOS=linux go build -i app.go

Specifying GOARCH=amd64 makes no difference.

Issue installing on Mac OS

Had some problems installing the lib on Mac, so just wanted to leave this here for future people searching for help:

after

brew install pkgconfig
brew install sqlite3

I've tried pkg-config --cflags --libs sqlite3, but got:

# pkg-config --cflags sqlite3
Package sqlite3 was not found in the pkg-config search path.
Perhaps you should add the directory containing `sqlite3.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sqlite3' found
exit status 1

What you need to do:

sudo PKG_CONFIG_PATH=/usr/local/Cellar/sqlite/3.7.15.2/lib/pkgconfig/ go get github.com/mattn/go-sqlite3

Please replace 3.7.15.2 with your version.

Thanks for the lib!

I have SQLite3 3.15.x on Windows 7 64 bit but the GCC and go (version 1.1) are 32 bit. The SELECT queries are not working for some reason. At times its leads to PANIC when the query is executed. Is there an issue with 32 bit version on Windows ? The following is the error returned with err.Error() : U??S??►??3?

cannot load github.com/mattn/go-sqlite3: module github.com/mattn/go-sqlite3@latest (v2.0.0+incompatible) found, but does not contain package github.com/mattn/go-sqlite3

This package doesn't seem to work with go modules. Here's a simple recipe in Docker, to make it easy to reproduce. Please tell me what I'm doing wrong:

$ docker run -it --rm golang:alpine
/go # apk add build-base
...
/go # mkdir /src
/go # cd /src
/src # cat - > main.go
package main
import (
        "fmt"
	_ "github.com/mattn/go-sqlite3"
)
func main() {
	fmt.Println("Hello world!")
}
/src # export CGO_ENABLED=1
/src # go mod init example.com
go: creating new go.mod: module example.com
/src # go get github.com/mattn/go-sqlite3
go: finding github.com/mattn/go-sqlite3 v2.0.0+incompatible
go: downloading github.com/mattn/go-sqlite3 v2.0.0+incompatible
go: extracting github.com/mattn/go-sqlite3 v2.0.0+incompatible
/src # go run .
build example.com: cannot load github.com/mattn/go-sqlite3: module github.com/mattn/go-sqlite3@latest (v2.0.0+incompatible) found, but does not contain package github.com/mattn/go-sqlite3

database is locked
We have a little app which has multiple goroutines all running queries and it often fails with "database is locked" :(

we're running with:

db, err := sql.Open("sqlite3", "test.db?cache=shared&mode=rwc")

PRAGMA journal_mode = WAL; PRAGMA synchronous = NORMAL;

sqlite3 -version 3.10.2 2016-01-20 15:27:19 17efb4209f97fb4971656086b138599a91a75ff9

Is this a known issue?
gcc issue on windows 64

While trying to do "go install github.com/mattn/go-sqlite3" I am getting the follwoing error. In one of the issues someone mentioned that we don't need gcc if we install go-sqlite3. Any help would be greatly appreciated.

[REQUEST] Memory with writeback

For performance reasons I would like to ask, if this is possible?

Opening an existing SQLite3 file and writing it into Memory. But everytime I write or read everything, I would like it to happen in memory (so way quicker). But after it is written an async task should write it back.

Currently I have tried it likle this:

db, err = sql.Open("sqlite3", "file:../data/tickets.db?mode=memory&cache=shared&_journal_mode=MEMORY")

But everytime I read/write it is way slower then other SQLite3 implementations - like in GORM, Python3 ... Here a write and read takes about 1,5ms, but for these others it actually is about 0,05ms which for me is a big difference.

So I would like to know what I migh be doing wrong., Are any of these settings (mode=memory&cache=shared&_journal_mode=MEMORY) not beneficial for performance? Even when I have the mode=memory set, it does not seem to be actually as fast as it should be if it would have been in memory. And it does not work, when I want it to load a DB from SSD into memory. I already have a DB, and this should be copied over into memory - I dont want to have a fresh DB everytime, as this is what is happening as soon as I use mode=memory.

Would be happy to get any feedback and I am open for an discussion.
Two process with Two sqlite db file

There are two program running in one server , and program A create connection to A.db, program B create connection to B.db.

When I use single Jmeter query A program's api and do some calculate in A.db, it can be 10 qps . (Now program B is idle) And when I use single Jmeter query B program's api and do some calculate in B.db, it can be 10 qps too. (Now program A is idle) But when I use **Two Jmeter ** query both A and B , each process only can be 5 qps.

A and B process use different sqlite DB, I don't why is 5qps per program. Please help me, thanks a lot.
Add ability to open database from a "virtual" file

I would like to be able to open an sqlite database given a file descriptor ( no filenames ). The mechanism to do so is described here https://sqlite.org/forum/forumpost/d4ed1b197ec94182 but the URI parser within this library prevents this technique from working.

The reason I want to do this is to utilize crash-safe anonymous inodes as implemented here: https://pkg.go.dev/github.com/tmthrgd/tmpfile#TempFile

The reason I can not use the :memory: + VACUUM INTO, is because the dataset is very large (almost a TiB ) and working with it in-RAM is problematic.

I am aware that the database will have to be opened with pragmas disabling WAL etc, as they rely on a "filename+extension" mechanism, and that's ok.

Thank you!
Add support for SQLCipher

This PR adds support for SQLCipher whilst keeping the existing embedded sqlite3 implementation. The support is enabled via the sqlcipher and libsqlcipher build tags, which respectively use the embedded SQLCipher implementation or link directly to libsqlcipher.

An upgrade script has been added to automate the inclusion of new versions of SQLCipher.

I believe that adding this support would benefit the Go ecosystem, as multiple unmaintained repos have flourished that are forks of this repo bolting on support for older versions of SQLCipher. Having support here would enable gorm users to benefit from the encryption feature without having to patch anything.
