Обсуждение: Row Nums

Hi,
I want to display serial numbers of rows selected by a query. I can do
this in Oracle by selecting a special attribute called 'rownum' (or
'rowno'). Can I do this in Postgres too? If not then is there any
alternative in Postgres?


Thanks,
Anand.

You might mean "oid." Try selecting oid form a table.

No I dont't want the oids but the serial number of a row in the present
output of the query. For e.g in Oracle we have:
select rownum,name from tablename;

will give me,

rownum | name
