SPI_FNUMBER(3)						  PostgreSQL 9.2.7 Documentation					    SPI_FNUMBER(3)

NAME
       SPI_fnumber - determine the column number for the specified column name

SYNOPSIS
       int SPI_fnumber(TupleDesc rowdesc, const char * colname)

DESCRIPTION
       SPI_fnumber returns the column number for the column with the specified name.

       If colname refers to a system column (e.g., oid) then the appropriate negative column number will be returned. The caller should be careful
       to test the return value for exact equality to SPI_ERROR_NOATTRIBUTE to detect an error; testing the result for less than or equal to 0 is
       not correct unless system columns should be rejected.

ARGUMENTS
       TupleDesc rowdesc
	   input row description

       const char * colname
	   column name

RETURN VALUE
       Column number (count starts at 1), or SPI_ERROR_NOATTRIBUTE if the named column was not found.
