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 Contacts (Name) VALUES ('John Doe')");
$affected = odbc_num_rows($result);

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Contacts SET Name = 'John Doe' WHERE ContactStatus = 'ACTIVE'");
$affected = odbc_num_rows($result);

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Contacts WHERE ContactId = 'c27221d7-8290-4204-9f3d-0cfb7c5a3d6f'");
$affected = odbc_num_rows($result);
