Hi, I'm doing the following call
SELECT  cts,landread,devread,(SELECT DISTINCT (case when a.landread != 2 then 1  else 0 end) as returnvar2 FROM "DUB"."ctsnotes" as a WHERE cts =  a.cts)as returnvar FROM "DUB"."ctsnotes"  as b
This returns "ERROR:  more than one row returned by a subquery used as an expression"

If I replace a.cts wtih a number it doesn't report an error.

I'm using Postgres for this call.

Any ideas guys ?
