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 \"sales_db\".\"public\".Orders (ShipCity) VALUES ('New York')");
$affected = odbc_num_rows($result);

UPDATE

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE \"sales_db\".\"public\".Orders SET ShipCity = 'New York' WHERE ShipCountry = 'USA'");
$affected = odbc_num_rows($result);

DELETE

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM \"sales_db\".\"public\".Orders WHERE Id = '10261'");
$affected = odbc_num_rows($result);
