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 Sheet(LastName) VALUES ('White')");
$affected = odbc_num_rows($result);

UPDATE

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Sheet SET LastName = 'White' WHERE FirstName = 'Bob'");
$affected = odbc_num_rows($result);

DELETE

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Sheet WHERE RowId = '5'");
$affected = odbc_num_rows($result);
