LIMIT {{size}}
Usage
package main
import (
"fmt"
"go-redash-query"
"log"
)
var (
redashQueryId = 1 // Redash QueryId
redashApiUrl = ""
redashAPiKey = ""
)
type TestUserData struct {
Id int `json:"id" mapstructure:"id"`
Name string `json:"name" mapstructure:"name"`
Email string `json:"email" mapstructure:"email"`
}
func main() {
client := go_redash_query.CreateClient(redashApiUrl, redashAPiKey)
queryData := go_redash_query.QueryData{
MaxAge: 10,
Parameters: go_redash_query.P{
"id": 1,
"size": 20,
},
}
job, err := client.CreateJobWithQuery(redashQueryId, queryData)
if err != nil {
log.Fatalf("CreateJobWithQuery %s", err)
}
fetchedData, err := client.Fetch(job)
if err != nil {
log.Fatalf("Fetch %s", err)
}
users := make([]TestUserData, 0)
err = fetchedData.GetDataWithStruct(&users)
if err != nil {
log.Fatal(err)
}
for _, user := range users {
fmt.Printf("%d %s %s\n", user.Id, user.Name, user.Email)
}
