SQL Server bit data type is 1 bit numeric datatype. It is also used as Boolean data type in SQL Server. You can store only 0, 1 or NULL in a bit data type. When used as Boolean data type, 0 is treated as false and 1 as true.
SQL Server BooleanThere is no boolean data type in SQL Server. However, a common option is to use the BIT data type. A BIT data type is used to store bit values from 1 to 64. So, a BIT field can be used for booleans, providing 1 for TRUE and 0 for FALSE.
Boolean Data TypeMySQL does not have a boolean (or bool) data type. Instead, it converts boolean values into integer data types (TINYINT). When you create a table with a boolean data type, MySQL outputs data as 0, if false, and 1, if true.
You can declare a boolean host variable as follows: EXEC SQL BEGIN DECLARE SECTION; boolean flag; EXEC SQL BEGIN DECLARE SECTION; In the Informix ESQL/C program, the following values are the only valid values that you can assign to boolean host variables: TRUE.
You could use the BIT datatype to represent boolean data. A BIT field's value is either 1, 0, or null.
