I'm beginning to replace my QBE queries with SQL and have an issue I 
can't seem to figure out.  For many reasons, there are times when a var 
I'm passing the the query will equal ".."

For example in building a query the user has the option to filter 
records for a particular field, if they don't filter any records (they 
want them all), the var gets the value of ".."

The QBE gets passed this var by use ~gsvar (with gsvar having the value 
of ..)

I'm not sure what I need to change this to for SQL.  In the SQL query I 
would still pass the var ~gsvar, but when gsvar has a value of .. the 
query fails.  I tried ANY and ALL, but both of those cause an error 
(invalid use of keyword).
