sql:execute

Allows arbitrary SQL statements to be executed. No result is returned.

`connection`	`expression`	The database connection. The value is an XPath expression, which must evaluate to a database connection object as returned by sql:connect.
`statement`	`{ expression }`	The SQL statement to be executed. The statements `COMMIT WORK` and `ROLLBACK WORK` (spelt exactly like that) are recognized specially, and cause calls on the JDBC `connection.commit()` and `connection.rollback()` methods respectively.
