Answer 1

I question the value of using a Boolean in TSQL. Every time I've started wishing for Booleans & For loops I realised I was approaching the problem like a C programmer & not a SQL programmer. The problem became trivial when I switched gears.

In SQL you are manipulating SETs of data. "WHERE BOOLEAN" is ineffective, as does not change the set you are working with. You need to compare each row with something for the filter clause to be effective. The Table/Resultset is an iEnumerable, the SELECT statement is a FOREACH loop.

Yes, "WHERE IsAdmin = True" is nicer to read than "WHERE IsAdmin = 1"

Yes, "WHERE True" would be nicer than "WHERE 1=1, ..." when dynamically generating TSQL.

and maybe, passing a Boolean to a stored proc may make an if statement more readable.

But mostly, the more IF's, WHILE's & Temp Tables you have in your TSQL, the more likely you should refactor it.
