Subject: Error with DISTINCT and AS keywords

Message-ID: <3D2C2140.7060003@software.b.uunet.de> (raw)

Hi,

I need some help to let this sql statement run with Postgres 7.2.1

Doesn't work:
select DISTINCT tnr, titel, 'TEST' AS testcol from tTitel;
ERROR:  Unable to identify an ordering operator '<' for type 'unknown'
         Use an explicit ordering operator or modify the query

If I remove the DISTINCT keyword it works:
select tnr, titel, 'TEST' AS testcol from tTitel;



Greetings,
Andreas
