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 sys_id, priority FROM incident WHERE category = ?", "request")
defer rows.Close()
for rows.Next() {
        var (
                sys_id string
                priority string
        )

        rows.Scan(&sys_id, &priority)
        fmt.Printf("sys_id = %s, priority = %s\n", sys_id, priority)
}

Reusable Statements

The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.

stmt, _ := db.Prepare("SELECT sys_id, priority FROM incident WHERE category = ?")
defer stmt.Close()

rows, _ := stmt.Query("request 1")
defer rows.Close()
for rows.Next() {
        var (
                sys_id string
                priority string
        )

        rows1.Scan(&sys_id, &priority)
        fmt.Printf("sys_id = %s, priority = %s\n", sys_id, priority)
}

rows, _ = stmt.Query("request 2")
defer rows.Close()
for rows.Next() {
        var (
                sys_id string
                priority string
        )

        rows2.Scan(&sys_id, &priority)
        fmt.Printf("sys_id = %s, priority = %s\n", sys_id, priority)
}
