SPI_CONNECT(3) PostgreSQL 9.3.2 Documentation SPI_CONNECT(3)NAMESPI_connect - connect a procedure to the SPI manager
SYNOPSIS
int SPI_connect(void)DESCRIPTIONSPI_connect 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.
If your procedure is already connected, SPI_connect will return the
error code SPI_ERROR_CONNECT. This could happen if a procedure that has
called SPI_connect directly calls another procedure that calls
SPI_connect. While recursive calls to the SPI manager are permitted
when an SQL command called through SPI invokes another function that
uses SPI, directly nested calls to SPI_connect and SPI_finish are
forbidden. (But see SPI_push and SPI_pop.)
RETURN VALUE
SPI_OK_CONNECT
on success
SPI_ERROR_CONNECT
on error
