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 AccountName, AccountNumber FROM Accounts WHERE Industry = ?", "Data/Telecom OEM")
defer rows.Close()
for rows.Next() {
        var (
                AccountName string
                AccountNumber string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT AccountName, AccountNumber FROM Accounts WHERE Industry = ?")
defer stmt.Close()

rows, _ := stmt.Query("Data/Telecom OEM 1")
defer rows.Close()
for rows.Next() {
        var (
                AccountName string
                AccountNumber string
        )

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

rows, _ = stmt.Query("Data/Telecom OEM 2")
defer rows.Close()
for rows.Next() {
        var (
                AccountName string
                AccountNumber string
        )

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