This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.
Returns TRUE on success, or FALSE on failure.
ingres_query() sends the given query to the Ingres server. This query must be a valid SQL query (see the Ingres SQL reference guide)
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.
Some types of SQL queries can't be sent with this function:
close (see ingres_close())
commit (see ingres_commit())
connect (see ingres_connect())
disconnect (see ingres_close())
prepare to commit
rollback (see ingres_rollback())
set autocommit (see ingres_autocommit())
all cursor related queries are unsupported
