and I agree with carlosdl remarks that it seems you have a major flaw in your database design and it could be re-designed in such a way to enable a smaller and faster procedure to process the report and achive the desired result.

Yes, I think that the query should be split in parts too, and each part should be tested separately, to make sure it does what it is supposed to do, before adding it to the complete statement.

Its hard to understand your question, but I’m only looking at your case function. The basic syntax of the search case function would be:-

Cae
WHEN Boolean _expression THEN result_expression
[...n]
[
ELSE else_result_expression
]
END

Example

Select Leasevendor, LeaseNumber,
CASE –some vendors have id of sales reps incorporated in LeaseNumbers
When LeaseVendor = ‘Trigon PS’ Then Substring(LeaseNumber,5,12)
When LeaseVendor Like ‘BB%’ Then SubString(LeaseNumber,9,8)
When LeaseVendor Like ‘MMEX%’ Then SubString(LeaseNumber,7,6)
When LeaseVendor = ‘DAFS’ Then SubString(LeaseNumber,8,11)
Else ‘UnKnown’
END [LeaseAgent], ContractDate [ContractDate]
from Lease

as per your case syntax, since you are repeating the case function for each office name values, then you must include DDS after each end statement of each case function, as in my example above

I’m not sure whether yiour CASE example will work but you must test it out separately with some dummy data first
