Hi,
I have a table with a column (int4), and I want to know how many
different numbers there are. In an example book I saw the query
SELECT COUNT (DISTINCT data ) FROM media;
by then I get
ERROR: parser: parse error at or near "distinct"
Is the query in error or does PostgreSQL not support this? How do I
then get the number of distinct data from my table?
TIA,
Micce
