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, FromName FROM Posts WHERE Target = ?", "11111")
defer rows.Close()
for rows.Next() {
        var (
                ID string
                FromName string
        )

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

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, FromName FROM Posts WHERE Target = ?")
defer stmt.Close()

rows, _ := stmt.Query("11111 1")
defer rows.Close()
for rows.Next() {
        var (
                ID string
                FromName string
        )

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

rows, _ = stmt.Query("11111 2")
defer rows.Close()
for rows.Next() {
        var (
                ID string
                FromName string
        )

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