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 \"SYSTEMDB\".\"DEMO\".Products (ProductName) VALUES ('Konbu')");
$affected = odbc_num_rows($result);

UPDATE

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE \"SYSTEMDB\".\"DEMO\".Products SET ProductName = 'Konbu' WHERE ProductName = 'Konbu'");
$affected = odbc_num_rows($result);

DELETE

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM \"SYSTEMDB\".\"DEMO\".Products WHERE Id = '22'");
$affected = odbc_num_rows($result);
