[firebird-support] Re: What is difference between Distinct and Distinct(FieldName)

[ijfqsftge...@spammotel.com [firebird-support]]

Distinct is not a function, so the parentheses are useless noise.

it is the same difference as between

SELECT R.RDB$FIELD_ID, R.RDB$RELATION_NAME 
FROM RDB$RELATIONS R

and 

SELECT (R.RDB$FIELD_ID), R.RDB$RELATION_NAME 
FROM RDB$RELATIONS R
