The following code examples show how to use data modification statements.

Procedure for Updates

You can use odbc_exec to execute data modification statements. This will return a resource which contains the number of affected rows.

INSERT

To insert updates:

$result = odbc_exec($cnx, "INSERT INTO MyCalendar(Description) VALUES ('My Calendar 2')");
$affected = odbc_num_rows($result);

UPDATE

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE MyCalendar SET Description = 'My Calendar 2' WHERE Status = 'confirmed'");
$affected = odbc_num_rows($result);

DELETE

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM MyCalendar WHERE Id = 'S'");
$affected = odbc_num_rows($result);
