A boolean is a data type that can store either a True or False value. This is often stored as 1 (true) or 0 (false). It’s named after George Boole who first defined an algebraic system of logic in the 19th century. Boolean values are common in programming languages, but do they e...
Yes, it's correct. 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-201...

To prevent this mismatch, you can convert VARCHAR2(1) data type to Boolean data type. VARCHAR2 data type stores variable-length text strings, and VARCHAR2(1) indicates that the string is 1 character in length or 1 byte. For more information...
