ingres_prepare — Prepare a query for later execution
$link
, string $query
)Prepares a query for execution by ingres_execute() .
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.
