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 Customers (Company) VALUES ('John')");
$affected = odbc_num_rows($result);

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Customers SET Company = 'John' WHERE CompanyName = 'CompanyName'");
$affected = odbc_num_rows($result);

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Customers WHERE Id = '12345'");
$affected = odbc_num_rows($result);
