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

To retrieve updates:

$result = odbc_exec($cnx, "UPDATE Objects SET Name = 'John' WHERE Column2 = 'Bob'");
$affected = odbc_num_rows($result);

To delete updates:

$result = odbc_exec($cnx, "DELETE FROM Objects WHERE Id = '6'");
$affected = odbc_num_rows($result);
