Package cloudsql exposes access to Google Cloud SQL databases.
|
|
|
|
This package does not work in App Engine "flexible environment".
|
|
|
|
This package is intended for MySQL drivers to make App Engine-specific
|
|
connections. Applications should use this package through database/sql:
|
|
Select a pure Go MySQL driver that supports this package, and use sql.Open
|
|
with protocol "cloudsql" and an address of the Cloud SQL instance.
|
|
|
|
A Go MySQL driver that has been tested to work well with Cloud SQL
|
|
is the go-sql-driver:
|
|
import "database/sql"
|
|
import _ "github.com/go-sql-driver/mysql"
|
|
|
|
db, err := sql.Open("mysql", "user@cloudsql(project-id:instance-name)/dbname")
|
|
|
|
|
|
Another driver that works well with Cloud SQL is the mymysql driver:
|
|
import "database/sql"
|
|
import _ "github.com/ziutek/mymysql/godrv"
|
|
|
|
db, err := sql.Open("mymysql", "cloudsql:instance-name*dbname/user/password")
|
|
|
|
|
|
Using either of these drivers, you can perform a standard SQL query.
|
|
This example assumes there is a table named 'users' with
|
|
columns 'first_name' and 'last_name':
|
|
|
|
rows, err := db.Query("SELECT first_name, last_name FROM users")
|
|
if err != nil {
|
|
log.Errorf(ctx, "db.Query: %v", err)
|
|
}
|
|
defer rows.Close()
|
|
|
|
for rows.Next() {
|
|
var firstName string
|
|
var lastName string
|
|
if err := rows.Scan(&firstName, &lastName); err != nil {
|
|
log.Errorf(ctx, "rows.Scan: %v", err)
|
|
continue
|
|
}
|
|
log.Infof(ctx, "First: %v - Last: %v", firstName, lastName)
|
|
}
|
|
if err := rows.Err(); err != nil {
|
|
log.Errorf(ctx, "Row error: %v", err)
|
|
}
