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, Leave_Type FROM [CData].[Employee Management].Leave_Types WHERE Leave_Type = ?", "Sick")
defer rows.Close()
for rows.Next() {
        var (
                ID string
                Leave_Type string
        )

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

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, Leave_Type FROM [CData].[Employee Management].Leave_Types WHERE Leave_Type = ?")
defer stmt.Close()

rows, _ := stmt.Query("Sick 1")
defer rows.Close()
for rows.Next() {
        var (
                ID string
                Leave_Type string
        )

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

rows, _ = stmt.Query("Sick 2")
defer rows.Close()
for rows.Next() {
        var (
                ID string
                Leave_Type string
        )

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