SSRS will automatically properly expand an "IN (@multi_valued_report_parameter)" if it's in an SSRS dataset and follows some basic rules. You may want to verify that you have a proper...

Let's assume you can get all that information.

You have conflicting needs: you don't want to slow down the login process, but you also don't want to store full string descriptions...

Don't see anything magical to let you get rid of any of the lookup joins :-).

There typically won't be, so all you can do is tune the lookups as much...

If you do need a prefix (and/or suffix), you can do this:

or:

CHARINDEX('''', string_column) > 0

Yes.

Typically a LEFT OUTER JOIN is used for that.

Say you're inserting names and want to avoid inserting one that's already in the table:

INSERT INTO dbo.names_table ( name )

SELECT wt.name

If you're 100% sure that no group_id will ever be more than one type, then that looks OK.

You probably want to consider using an IDENTITY column to automatically assign one...

Interesting too is that an empty string does not work for decimal values:

SELECT 1.1+''

But it again does work for dates:

SELECT CAST('' as datetime)

44 out of 48 is definitely too high. Keep in mind that the OS needs some RAM to manage the RAM itself.

Since you have to ALTER columns only one at a time (why, MS, why??), I'd create a new table and INSERT every row into it, converting every column...
