The query becomes part of the currently open transaction. If
|
|
there is no open transaction, <span class="function"><a href="ingres_query.html" class="function">ingres_query()</a></span>
|
|
opens a new transaction. To close the transaction, you can
|
|
call either <span class="function"><a href="ingres_commit.html" class="function">ingres_commit()</a></span> to commit the changes
|
|
made to the database or <span class="function"><a href="ingres_rollback.html" class="function">ingres_rollback()</a></span> to
|
|
cancel these changes. When the script ends, any open transaction
|
|
is rolled back (by calling
|
|
<span class="function"><a href="ingres_rollback.html" class="function">ingres_rollback()</a></span>). You can also use
|
|
<span class="function"><a href="ingres_autocommit.html" class="function">ingres_autocommit()</a></span> before opening a new
|
|
transaction to have every SQL query immediately committed.
