How To Use Boolean In Sql

The equivalent is a BIT field. In SQL you use 0 and 1 to set a bit field just as a yesno field in Access. In Management Studio it displays as a falsetrue value at least in recent versions. When accessing the database through ASP.NET it will expose the field as a boolean value.

The SQL Boolean data type is not included in SQL Server. Other databases like Oracle and MySQL include the Boolean data type that accepts the values of TRUE, and FALSE.

The Boolean data type is a fundamental concept in programming and database management that represents truth values. Essentially, it can have one of two states true or false. This binary nature makes it particularly useful in decision-making processes, filtering data, and constructing conditional logic within SQL queries.

Boolean expressions are a core concept in SQL, helping to filter and manipulate data based on conditions. These expressions evaluate to one of three Boolean values TRUE, FALSE, or UNKNOWN. They are extensively used in WHERE clauses, HAVING clauses, and conditional statements to query and retrieve specific data from a database.

When you use BOOL and BOOLEAN, it automatically sets the TINYINT 1 data type to the column. So, you can say that BOOL and BOOLEAN are the aliases for TINYINT, and all three can be used alternatively. The BIT data type can also be used to represent the boolean values in MySQL.

You will learn how to use the MySQL BOOLEAN data type, which is the synonym of TINYINT1, and how to manipulate Boolean values.

In this extensive guide, you received the full treatment on boolean data types in the SQL universe - from internals and querying to real-world use cases. We dug into how databases like PostgreSQL, MySQL, and SQL Server differ significantly in implementing booleans under the covers.
