SPI_fnumber

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.
