mixed ingres_unbuffered_query ( resource $link , string $query [, array $params [, string $types ]] )
ingres_unbuffered_query() sends the given query to the Ingres server. The query becomes part of the currently open transaction. If there is no open transaction, ingres_unbuffered_query() opens a new transaction. To close the transaction, you can call either ingres_commit() to commit the changes made to the database or ingres_rollback() to cancel these changes. When the script ends, any open transaction is rolled back (by calling ingres_rollback()). You can also use ingres_autocommit() before opening a new transaction to have every SQL query immediately committed. Ingres allows only a single unbuffered statement to be active at any one time. The extension will close any active unbuffered statements before executing any SQL. In addition you cannot use ingres_result_seek() to position the row before fetching.

ingres_unbuffered_query() returns a query result identifier when there are rows to fetch; else it returns FALSE when there are no rows, as is the case of an INSERT, UPDATE, or DELETE statement. To see if an error occurred, use ingres_errno(), ingres_error(), or ingres_errsqlstate().
