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 Region, Product FROM [Workspace].[Model].[Sales] WHERE Value = ?", "100")
defer rows.Close()
for rows.Next() {
        var (
                Region string
                Product string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT Region, Product FROM [Workspace].[Model].[Sales] WHERE Value = ?")
defer stmt.Close()

rows, _ := stmt.Query("100 1")
defer rows.Close()
for rows.Next() {
        var (
                Region string
                Product string
        )

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

rows, _ = stmt.Query("100 2")
defer rows.Close()
for rows.Next() {
        var (
                Region string
                Product string
        )

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