SPI_FNUMBER(3)		PostgreSQL 9.6.19 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.
