<TD colspan="3"><P>Before your program terminates you need to free all resources you
have allocated. If you checked the source on the previous page, you certainly
spotted <CODE><A HREF="gloss.html#free">SQLFreeHandle</A></CODE>. This function must be used
to free each allocated handle. It expects a parameter which states the type of the handle
to be freed and the handle itself. So if you want to free an environment handle you should
call (in our example program):</P>
<CODE>
SQLFreeHandle(SQL_HANDLE_ENV, V_OD_Env);
</CODE>
<P>
Before you free any handle make sure that it is no longer needed, wouldn't be funny, if you
released to connection handle but forgot to close the connection ;)</P>
<P>
And if you want to close a connection you need <CODE><A HREF="gloss.html#clos">SQLDisconnect</A></CODE>.
This closes the connection associated with the connection handle offered as argument to <CODE>SQLDisconnect</CODE>.
In our programm we need to call:</P>
<CODE>
SQLDisconnect(V_OD_hdbc);
</CODE>
<P>
If you need source code, please have a look <A HREF="conne.html#list">here</A>.</P>
