NO!! CASE is an expression. Expressions return scalar values. Columns are not fields. We do not use BIT flags in SQL.
These are not little mistakes; these are fundamental misconceptions. Your whole mindset is wrong. Please stop trying to write SQL until you have read at least one book on RDBMS and SQL.
