>Description</H2
><P
> <CODE
CLASS="FUNCTION"
>SPI_connect</CODE
> opens a connection from a
procedure invocation to the SPI manager. You must call this
function if you want to execute commands through SPI. Some utility
SPI functions can be called from unconnected procedures.
</P
><P
> If your procedure is already connected,
<CODE
CLASS="FUNCTION"
>SPI_connect</CODE
> will return the error code
<SPAN
CLASS="RETURNVALUE"
>SPI_ERROR_CONNECT</SPAN
>. This could happen if
a procedure that has called <CODE
CLASS="FUNCTION"
>SPI_connect</CODE
>
directly calls another procedure that calls
<CODE
CLASS="FUNCTION"
>SPI_connect</CODE
>. While recursive calls to the
<ACRONYM
CLASS="ACRONYM"
>SPI</ACRONYM
> manager are permitted when an SQL command
called through SPI invokes another function that uses
<ACRONYM
CLASS="ACRONYM"
>SPI</ACRONYM
>, directly nested calls to
<CODE
CLASS="FUNCTION"
>SPI_connect</CODE
> and
<CODE
CLASS="FUNCTION"
>SPI_finish</CODE
> are forbidden.
(But see <CODE
CLASS="FUNCTION"
>SPI_push</CODE
> and <CODE
CLASS="FUNCTION"
>SPI_pop</CODE
>.)
