Great info, thank you!
One issue I ran into was then I was converting a column that was of type int to a varchar. Your example doesn’t allow for that difference. Here is what needs to change in the function. Consider myIDs column as int

SELECT @myidList = COALESCE(@myidList + ‘, ‘, ”) + CAST(myIDs as varchar(100))

But… great and useful example. Thanks again!

[...] a list of record data from a join Very interesting post here. Only works in MS-SQL but it returns a list of data in a column in your query. I quite often need [...]

Without a visual example to see if I understand this right, I’m not sure if I have the same solution or not…but for Oracle. I found after much searching some code that would allow me to pull many related rows from a table and comma separate them into a single column connected to the parent table. i.e. table A has a key to join to table B. table B is many to one relation of A. If my goal is to query A and get a single row back for each record in A but there are say 4 children records in B, normally you would get 4 rows back in your join. This will instead return 1 row, with A’s value in one column and B1, B2, B3, B4 combined in 1 row/column.

Anyway, I can dig out the code if anyone is interested. It requires creating a custom function and a procedure if I recall correctly. Should be pretty easy to do and its only about 25 lines of code. Email hartwichr@hotmail.com if you are interested in an Oracle solution.
