When specifying columns in a GROUP BY clause would it be possible to use a
wildcard to specify all columns coming from a given relation?

 

SELECT 

rosum.*, 

sum(ld.amount) AS ldcost, 

count(ld.amount) AS ldcount, 

rosum.rocost + sum(ld.amount) AS netbal

 

FROM (

SELECT w.s_id, w.accountnumber, w.date_reference, w.invoicenumber, 

sum(w.amount_cost) AS rocost, count(w.amount_cost) AS rocount

FROM wiplaboradpstaging w

WHERE <FILTER>

GROUP BY w.s_id, w.accountnumber, w.date_reference, w.invoicenumber

) rosum

 

LEFT JOIN ledgerdetail ld ON (

rosum.s_id = ld.s_id AND 

rosum.accountnumber = ld.accountnumber AND 

rosum.invoicenumber = ld.reference

)

 

GROUP BY rosum.*  < ------- WildCard Group By Since the rosum sub-query has
already been subjected to a GROUP BY

 

Attempt to run this query in 9.0.3 results in:

 

"SQL Error: ERROR:  column "rosum.s_id" must appear in the GROUP BY clause
or be used in an aggregate function

LINE 2: rosum.*,"
