sgv writes "The below query has a very poor response time. Can someone suggest a better alternative for this query.
Select Table1.Xfield,
AVG(Etable.field3),
AVG(Ptable.field3),
AVG(Btable.field3)
From Table1 LEFT JOIN
Etable ON
Table1.Xfield = Etable.Xfield
LEFT JOIN
Ptable ON
Table1.Xfield = Ptable.Xfield
LEFT JOIN
Btable ON
Table1.Xfield = Btable.Xfield
Group By Table1.fldate, Table1.Xfield
Thanks in advance for your help.
