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...
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...

Until MySQL implements a bit datatype, if your processing is truly pressed for space and/or time, such as with high volume transactions, create a TINYINT field called bit_flags for all your boolean variables, and mask and shift the boolean bit you desire in your SQL query. For instance,...
I have noticed the default mapping for boolean in SQL Server is marked as tinyint in the document. https://www.prisma.io/docs/orm/reference/prisma-schema-reference#default-type-mappings-1 However, SQL Server uses bit as shown below: https://learn.microsoft.com/en-us/sql/t-sql/data-type...
The boolean datatype comes from the comparison operation. SQL is not Python and you cannot have ...
FWIW : There's a bit type in PostgreSQL : If MSSQL type bit should be mapped, it certainly should be on bit/varbits : https://www.postgresql.org/docs/12/datatype-bit.html boolean type is 1 byte wide. Semantically, bits words should be mapped to bit not to boolean nor to tinyint...
