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 SMVendorID, Category FROM Vendors WHERE SMVendorID = ?", "S123456")
defer rows.Close()
for rows.Next() {
        var (
                SMVendorID string
                Category string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT SMVendorID, Category FROM Vendors WHERE SMVendorID = ?")
defer stmt.Close()

rows, _ := stmt.Query("S123456 1")
defer rows.Close()
for rows.Next() {
        var (
                SMVendorID string
                Category string
        )

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

rows, _ = stmt.Query("S123456 2")
defer rows.Close()
for rows.Next() {
        var (
                SMVendorID string
                Category string
        )

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