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 Customers (Name) VALUES ('Hook, Captain')");
$affected = odbc_num_rows($result);

UPDATE

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Customers SET Name = 'Hook, Captain' WHERE Name = 'Cook, Brian'");
$affected = odbc_num_rows($result);

DELETE

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Customers WHERE Id = '10456255-0015501366'");
$affected = odbc_num_rows($result);
