Command Questions Crystal XI R2

Question

I have 2 sql commands that run in under 3 minutes in sql as follows, the problem I am having is when I pull them into Crystal they run and hang forever, I have killed it everytime after an hour, I am linking them together on the d.yearmonthnum, I have tried linking every possible way, can anybody see any glaring reason why this won't work??? Thanks in advance.
SQL 1

SUM (Case when ph.batchtype IN ('PCR', 'PAR', 'PUR') then -PH.Fee1
when ph.batchtype IN ('PC', 'PA', 'PU') then ph.Fee1
else 0
end) AS Fees,
SUM (Case when ph.batchtype = 'DAR' then -PH.Paid1

Answer 1

Part of what happens when you use multiple commands in a report is that Crystal can't link the data on the database server.  So, it pulls ALL of the data from both queries to the machine where the report is being run and then links the data and applies any filters IN MEMORY.  If the unfiltered result of either or both queries is large, this will take a lot of time and if there isn't a lot of memory on the machine, it will also include a lot of disk swapping.  This will dramatically increase the amount of time it takes to run the report.
I agree with what Brian said - either use a stored procedure or update your command so that it joins the data from both queries in a single command.
