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 Customer (Name) VALUES ('CDATA000002')");
$affected = odbc_num_rows($result);

UPDATE

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Customer SET Name = 'CDATA000002' WHERE Name = 'Jon Doe'");
$affected = odbc_num_rows($result);

DELETE

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Customer WHERE Id = '22'");
$affected = odbc_num_rows($result);
