Note that SQL Server uses three valued logic (true, false, and NULL), since NULL is a possible value of the bit data type. Here are the relevant truth tables - More information on three valued logic- Example of three valued logic in SQL Server http://www.firstsql.com/i...
the data type of the Boolean data in SQL Server is bit data type, and it could store 1,0 and NULL.Also, the string values TRUE and FALSE could be converted to bit values, which is mentioned at /en-us/sql/t-sql/data-types/bit-transact-sql?view=sql-server-2017#remarks...
The boolean type for SQL should support 3 values - TRUE, FALSE and UNKNOWN (and also, the non-value NULL). So bit isn't actually a good match here. Given that SQL Server has no support for the data type, we should not expect to be able to write literals of that "type". Share I...
