Modifying Data

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.

To insert updates:

$result = odbc_exec($cnx, "INSERT INTO Movies (MovieRating) VALUES ('R')");
$affected = odbc_num_rows($result);

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Movies SET MovieRating = 'R' WHERE MovieRating = 'R'");
$affected = odbc_num_rows($result);

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Movies WHERE Id = '70f6284d2a395396dbb3a60b4ce3d2d6'");
$affected = odbc_num_rows($result);
