What is the best data type to store boolean values in a database? which is supported by mostly used RDBMS types such as Mysql,oracle,postgres,mssql

If the DBMS supports a real boolean
type (e.g. PostgreSQL) then use that. If it doesn't I usually prefer an integer value combined with a check constraint that ensures that only 0
and 1
can be stored. In my experience it also makes sense to define the column as NOT NULL
as well. Having a NULL
value for a boolean is always somewhat confusing.
You won't find a single datatype that works for all DBMS. I would always use the "best" one that the DBMS offers.
