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 MarketingCampaigns (Subject) VALUES ('March Top 50 football highlights.')");
$affected = odbc_num_rows($result);

UPDATE

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE MarketingCampaigns SET Subject = 'March Top 50 football highlights.' WHERE Id = '17693'");
$affected = odbc_num_rows($result);

DELETE

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM MarketingCampaigns WHERE Id = '16500'");
$affected = odbc_num_rows($result);
