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 No, Contact FROM Customer WHERE Name = ?", "CData, Inc.")
defer rows.Close()
for rows.Next() {
        var (
                No string
                Contact string
        )

        rows.Scan(&No, &Contact)
        fmt.Printf("No = %s, Contact = %s\n", No, Contact)
}

Reusable Statements

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

stmt, _ := db.Prepare("SELECT No, Contact FROM Customer WHERE Name = ?")
defer stmt.Close()

rows, _ := stmt.Query("CData, Inc. 1")
defer rows.Close()
for rows.Next() {
        var (
                No string
                Contact string
        )

        rows1.Scan(&No, &Contact)
        fmt.Printf("No = %s, Contact = %s\n", No, Contact)
}

rows, _ = stmt.Query("CData, Inc. 2")
defer rows.Close()
for rows.Next() {
        var (
                No string
                Contact string
        )

        rows2.Scan(&No, &Contact)
        fmt.Printf("No = %s, Contact = %s\n", No, Contact)
}
