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 CreatorName, Text FROM Comments WHERE AppId = ?", "1354841")
defer rows.Close()
for rows.Next() {
        var (
                CreatorName string
                Text string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT CreatorName, Text FROM Comments WHERE AppId = ?")
defer stmt.Close()

rows, _ := stmt.Query("1354841 1")
defer rows.Close()
for rows.Next() {
        var (
                CreatorName string
                Text string
        )

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

rows, _ = stmt.Query("1354841 2")
defer rows.Close()
for rows.Next() {
        var (
                CreatorName string
                Text string
        )

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