Re: Confused with the logic.Plzz Help.

Question

Hi All,
I am a newbie to Crystal Reports. I am generating a work center report and have some issues with it.
I have an Activity_type and Activity_rate fields grouped by Person responsible for each Plant. I need to get the Activity_type by date.
Logic to do this:
  table1.ARBID=table2.OBJID and
  table2.OBJID=table3.OBJID and
  table1.DATE >= table3.Date
[Imp note: Table1.ARBID is not linked to Table2.OBJID(if i link them, all other data is not getting displayed)].
Also, Logic for Activity_Rate:
Select Table4.TKG001
from table4
where table4.objectno = @form_act_Objno
How can i work with this logic in Crystal reports.
Any kind of advice is appreciated.
Thanks In Advance!!

Ragini,
If you are building your data set by adding tables and linking them in the Database Expert then you drawl lines from key field to key field. Right click the link lines and alter the link properties as needed.
The fact that you you used SQL to illustrate your problem leads me to believe that you may actually know SQL. If that's the case you can use a SQL Command as your data source using the native SQL syntax for your database.
something like this:
SELECT
Fieild List
FROM Table1 AS t1
INNER JOIN Table2 AS t2 ON t1.ARBID = t2.OBJID
INNER JOIN Table3 AS t3 ON t2.OBJID = t3.OBJID AND t1.DATE >= t3.DATE
Not sure where Table 4 is coming into the mix... but you can easily pass parameter values back to a SQL Command:
where table4.objectno = '{?form_act_Objno}'
If @form_act_Objno is a formula field... You can't directly pass the results of a formula back to a SQL Command... (You can get to pass into the SQL using sub-report parameters, but it's far from intuitive, requires the use of sub-reports, and id outside the scope of do-ability for most new comers).
If it's a user supplied parameter value... no problem.
HTH,
