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 Events (Title) VALUES ('John')");
$affected = odbc_num_rows($result);

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Events SET Title = 'John' WHERE Title = 'CDATA_EVENT'");
$affected = odbc_num_rows($result);

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Events WHERE Id = 'cfd2c068-bdcb-4a01-8fad-280c3230a0f7'");
$affected = odbc_num_rows($result);
