ingres_query — Send an SQL query to Ingres


Описание

mixed ingres_query ( resource $link , string $query [, array $params [, string $types ]] )

ingres_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_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.
