Maybe a trivial question, maybe it's foreign from SQL, I'dont know...
How to add a column which stands for the row number in each row of the
result? E.g.:
row_no | column1 | column2 | ...
-------+---------+---------+ ... 1 | datum11 | datum12 | ... 2 | datum21 | datum22 | ... ... | ... | ...
|...
I didn't find anything in the docs.
TIA, Zoltan
