You're welcome... if you run my code, make sure the CREATE TABLE code for Protocol is before the code for Enroll. (That part was confusing in my post, I...

You can do it using CROSS APPLY.

Read these two articles (definitely worth the read!):

And don't forget MSDB. That's where all your jobs etc are stored.

okay... I think this fixes the "you can't report symptoms after you're dead" issue...

Okay, here's the DELETE as a CTE, which is probably the easiest way to do it... (once you read the crib notes)

; WITH CTE_DupeAddr(DupeID, ID, Cid, FName, LName, DOB, City)...

So sue me.

So in theory they could merge two records that don't match? Could you post an example? Explain why you can't do it with either a CTE or a...

Cursor is a bad word around here... careful.

That said, I don't think you need a cursor at all.

CREATE Table #TableA

(

ID int IDENTITY(1,1),

SID INT,

FNAME varchar(50),

LNAMEvarchar(50),

DOB date,

CITYvarchar(50),

IsActive bit

Made a little progress. I added some columns just to understand what's going on (since I'm sort of stumbling around in the Dark Ages). Here's my latest attempt:

What's the maximum number of cycles? Can they overlap? Presumably you want a datetime on each symptom row?

As best I can remember, protocols run for a non-predetermined period of...

Correct. It's modeling cancer treatment therapy, so sometimes they get fatal complications, and after that you can't test them anymore. (Cheery huh?)

Okay, I re-read SQLKiwi's articles on APPLY. Basically, the "left" side is the set of enrollees to "process", and the right side is the symptoms. Got that part....

Cruel Taskmaster <g>,

I have a dumb question - if I use a non-looping solution, how do I indicate that no more treatment cycles should be added for an enrollee after...

I probably am skipping a class. The challenge I couldn't get around was this one:
