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 Projects (Name) VALUES ('John')");
$affected = odbc_num_rows($result);

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Projects SET Name = 'John' WHERE Name = 'Tax Checker'");
$affected = odbc_num_rows($result);

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Projects WHERE Id = '11111111-c6be-e111-1f1e-00155d055681'");
$affected = odbc_num_rows($result);
