Parameterized Statements
The following code example shows how to bind parameters to create parameterized statements.
Single-Use Statements
The Query and Exec functions both accept additional parameters for binding query parameters to values.
rows, _ := db.Query("SELECT Id, Color FROM Tags WHERE CustomerId = ?", "1368175")
defer rows.Close()
for rows.Next() {
var (
Id string
Color string
)
rows.Scan(&Id, &Color)
fmt.Printf("Id = %s, Color = %s\n", Id, Color)
}
Reusable Statements
The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.
stmt, _ := db.Prepare("SELECT Id, Color FROM Tags WHERE CustomerId = ?")
defer stmt.Close()
rows, _ := stmt.Query("1368175 1")
defer rows.Close()
for rows.Next() {
var (
Id string
Color string
)
rows1.Scan(&Id, &Color)
fmt.Printf("Id = %s, Color = %s\n", Id, Color)
}
rows, _ = stmt.Query("1368175 2")
defer rows.Close()
for rows.Next() {
var (
Id string
Color string
)
rows2.Scan(&Id, &Color)
fmt.Printf("Id = %s, Color = %s\n", Id, Color)
}
