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 City, Country FROM Contacts WHERE VID = ?", "123456789")
defer rows.Close()
for rows.Next() {
        var (
                City string
                Country string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT City, Country FROM Contacts WHERE VID = ?")
defer stmt.Close()

rows, _ := stmt.Query("123456789 1")
defer rows.Close()
for rows.Next() {
        var (
                City string
                Country string
        )

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

rows, _ = stmt.Query("123456789 2")
defer rows.Close()
for rows.Next() {
        var (
                City string
                Country string
        )

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