ingres_query — Send a SQL query to Ingres II
설명
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 either call 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.
