Select Query Needed

Hi there,

i have 3 tables in my database (MS Access) namly  i)EmpReg ii) EmpDate iii)cmpDetails
the tables has the following columns.

i)EmpReg
emp_code (int)
emp_Fname (varchar)
emp_Lname (varchar)
cmp_code  (int)    

ii) EmpDate
emp_code (int)
emp_date (datetime)
emp_status (double)      --> only  0 [OR]  0.5  [OR] 1 will be stored in this column

iii)cmpDetails
cmp_code (int)          
cmp_name (varchar)

so i need a query to  select sum of emp_status   i.e. sum(emp_status)   from  EmpDate  on emp_date  date range given and along with emp_code, emp_Fname, emp_Lname from EmpReg   and cmp_name  from cmp_name

Best regards,
an_and

seems to be a reasonable query in SQL syntax, open a new query window in design mode, right click the header, put into SQL view and paste:

Select R.emp_code, R.emp_Fname, R.emp_Lname ,C.cmp_name , sum(D.emp_status)
from EmpReg R ,EmpDate D ,cmpDetails C
where R.cmp_code = C.cmp_code
and R.emp_code = D.emp_code
Group by R.emp_code, R.emp_Fname, R.emp_Lname ,C.cmp_name

Then run the query. Sometimes, when you save, it tries to resort to access, so might need to open again, tidy (all the brackets) and save again...

@pratima_mcs: sorry didn't see your posting - had zero replies when I started to type - absolutely perfect code though :)

Oh, and before the group by put in your "where" clause for date range...
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

OK, just to be different, lets give pratima_mcs the credit for the equi join, and I will use traditional join syntax:

Select R.emp_code, R.emp_Fname, R.emp_Lname ,C.cmp_name , sum(D.emp_status)
from EmpReg R
inner join EmpDate D on R.emp_code = D.emp_code
inner join cmpDetails C on R.cmp_code = C.cmp_code
where D.emp_date between "thisdate" and "thatdate"
Group by R.emp_code, R.emp_Fname, R.emp_Lname ,C.cmp_name

both pratima_mcs and mark wills give the same solution i give point to pratima_mcs  for her first and fast reply

Finally after modifying the query  here's the query

SELECT R.emp_code, R.emp_Fname, R.emp_Lname, C.cmp_name, sum(D.emp_status)
FROM EmpReg AS R, EmpDate AS D, cmpDetails AS C
WHERE R.cmp_code=C.cmp_code And R.emp_code=D.emp_code And D.emp_Date Between #11/8/2006# And #11/17/2006#
GROUP BY R.emp_code, R.emp_Fname, R.emp_Lname, C.cmp_name;
