Parameterized Statements

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 Id, [address-city] FROM Patient WHERE [name-use] = ?", "Bob")
defer rows.Close()
for rows.Next() {
        var (
                Id string
                [address-city] string
        )

        rows.Scan(&Id, &[address-city])
        fmt.Printf("Id = %s, [address-city] = %s\n", Id, [address-city])
}

Reusable Statements

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

stmt, _ := db.Prepare("SELECT Id, [address-city] FROM Patient WHERE [name-use] = ?")
defer stmt.Close()

rows, _ := stmt.Query("Bob 1")
defer rows.Close()
for rows.Next() {
        var (
                Id string
                [address-city] string
        )

        rows1.Scan(&Id, &[address-city])
        fmt.Printf("Id = %s, [address-city] = %s\n", Id, [address-city])
}

rows, _ = stmt.Query("Bob 2")
defer rows.Close()
for rows.Next() {
        var (
                Id string
                [address-city] string
        )

        rows2.Scan(&Id, &[address-city])
        fmt.Printf("Id = %s, [address-city] = %s\n", Id, [address-city])
}
