Hi,
I am trying to do group by multiple columns in oracle procedure but i should put all the columns in group by whatever it is present in select query
Do all columns in a SELECT list have to appear in a GROUP BY clause?
How would i write the query to mention only the particular columns whichever it is require in group by clause?
If i don't put all the columns in group by am getting error like group by not an expression
