What SQL data type is used to store TRUE or FALSE values?

The SQL data type used to store TRUE or FALSE values is Boolean. This data type specifically represents two possible states: true and false, making it ideal for conditions and flags within a database.

Using a Boolean data type allows for more efficient storage and processing of binary states compared to other types. Unlike a text data type, which is meant for strings and can consume more space, the Boolean type is optimized for this specific purpose. Furthermore, while integers can represent true and false states (for example, 1 for true and 0 for false), they are not as semantically clear as using the Boolean type. The date type, on the other hand, serves entirely different purposes related to date and time values.

Thus, the Boolean data type is specifically designed for logical operations and conditions within SQL, making it the most suitable choice for directly representing true or false values.
