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 [CData].[Administrators].Users (Email) VALUES ('John')");
$affected = odbc_num_rows($result);

UPDATE

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE [CData].[Administrators].Users SET Email = 'John' WHERE Id = '39ef9b6f-5973-4701-bd19-7950d4b7d6e0'");
$affected = odbc_num_rows($result);

DELETE

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM [CData].[Administrators].Users WHERE Id = '39ef9b6f-5973-4701-bd19-7950d4b7d6e0'");
$affected = odbc_num_rows($result);
