Parsing field value based upon derived dataset

I am attempting to CASE a column in a view based upon a select against a separate table.

The select will return a number of distinct values; this will then be used to CASE the column in the view. This column will contain space-separated values in the form '1 2 3 4 5 A C D', etc

Consequently, if the select statements returns values of 1,2,3 and any or all of these values appears in the view column, the column should be updated as 'COMPLIANT' for example.

We're no doubt looking at a UDF here but any pointers you could offer would be appreciated.

Thanks

>>space-separated values

That design is a violation of first normal form -- and makes stuff like this MUCH harder.  Is correcting the design an option at this point?

Assuming it is not ... perhaps something like ...

Select CASE When (Select count(*) From MainTable Inner Join otherTable on MainTable.SpaceSeparatedColumn like '%' + otherTable.DistinctValue + '%') > 0 then 'COMPLIANT' else 'Not Compliant' END

Hi Daniel

Unfortunately the design is inherited and due to pressure of timescale there is very little I can do about that.

However, what you have suggested does sound like a possibility. I'll investigate further and get back to you.

OK, if you need code that more closely fits your table structure, please post that structure.
