Обсуждение: Count & Distinct

Search a lot of archives and have come up with very little (much old)

obviously

>>> select count(distinct(row)) from table;

Does not work so what is the work around? I have tried a bunch of stuff.

Thanks,
J

hhs=# select count(distinct(fieldorder)) from temp_fields;
 count
-------
     3

I just tried it really quick and it worked fine.. What are you getting with
what table/view and query?
