SPI_FNUMBER(3) PostgreSQL 18.6 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., ctid) then the appropriate neg- ative 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 for user-defined columns), or SPI_ER- ROR_NOATTRIBUTE if the named column was not found.
