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.

To insert updates:

$result = odbc_exec($cnx, "INSERT INTO Accounts (Name) VALUES ('John')");
$affected = odbc_num_rows($result);

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Accounts SET Name = 'John' WHERE City = 'Raleigh'");
$affected = odbc_num_rows($result);

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Accounts WHERE Id = 'a1f7b7c1-1ea9-4305-82b8-ab482db90a5f'");
$affected = odbc_num_rows($result);
