marmar writes "Hi

I need help with a query. I have two tables that looks the same:

table 1
var1
var2
var3
var4

table 2
var1
var2
var3
var4

What I want to do is group and order by var2, var3 and var4 and do a count(table1.var1)+ count(table2.var1)/2 (a mean) for the same groups. I'm not sure how to do this. Any suggestions ?

Thanks in advance !"

Not sure what you want.

select table1.var2, table1.var3, table1.var4 , (1.0 * count(table1.var1)+ count(table2.var1))/2
from table1 join table2
on table1.var2 = table2.var2 and table1.var3 = table2.var3 and table1.var4 = table2.var3
group by table1.var2, table1.var3, table1.var4

==========================================
Cursors are useful if you don't know sql.
DTS can be used in a similar way.
