You must call this function after completing the SPI operations needed during your procedure's current invocation. You do not need to worry about making this happen, however, if you abort the transaction via <TT CLASS="LITERAL" >elog(ERROR)</TT >. In that case SPI will clean itself up automatically. </P ><P > If <CODE CLASS="FUNCTION" >SPI_finish</CODE > is called without having a valid connection, it will return <TT CLASS="SYMBOL" >SPI_ERROR_UNCONNECTED</TT >. There is no fundamental problem with this; it means that the SPI manager has nothing to do. </P ></DIV ><DIV CLASS="REFSECT1" ><A NAME="AEN60054" ></A ><H2 >Return Value</H2 ><P ></P ><DIV CLASS="VARIABLELIST" ><DL ><DT ><TT CLASS="SYMBOL" >SPI_OK_FINISH</TT ></DT ><DD ><P > if properly disconnected </P ></DD ><DT ><TT CLASS="SYMBOL" >SPI_ERROR_UNCONNECTED</TT ></DT ><DD ><P > if called from an unconnected procedure </P ></DD ></DL ></DIV ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="spi-spi-connect.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="spi-spi-push.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >SPI_connect</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="spi-interface.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >SPI_push</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
