Modifying Data
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 Posts(FromName) VALUES ('User 2')"); $affected = odbc_num_rows($result);
UPDATE
To retrieve updates:
$result = odbc_exec($cnx, "UPDATE Posts SET FromName = 'User 2' WHERE Target = '11111'"); $affected = odbc_num_rows($result);
DELETE
To delete updates:
$result = odbc_exec($cnx, "DELETE FROM Posts WHERE Id = '11111_22222'"); $affected = odbc_num_rows($result);
