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 Student_ID, Transaction_Number FROM [CData].[Btrieve].Billing WHERE Student_ID = ?", "22")
defer rows.Close()
for rows.Next() {
        var (
                Student_ID string
                Transaction_Number string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT Student_ID, Transaction_Number FROM [CData].[Btrieve].Billing WHERE Student_ID = ?")
defer stmt.Close()

rows, _ := stmt.Query("22 1")
defer rows.Close()
for rows.Next() {
        var (
                Student_ID string
                Transaction_Number string
        )

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

rows, _ = stmt.Query("22 2")
defer rows.Close()
for rows.Next() {
        var (
                Student_ID string
                Transaction_Number string
        )

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