The BIT data type is used to store a bit (0 or 1).

Syntax

BIT

Remarks

BIT is an integer type that can store the values 0 or 1.

By default, the BIT data type does not allow NULL.

When converting a string to a BIT, leading and trailing spaces are removed. If the leading character is '+' it is ignored. If the leading character is '-' the remaining digits are interpreted as a negative number. Leading '0' characters are skipped, and the remaining characters are converted to an integer value. An error is returned if the value is out of the valid range for the destination data type, if the string contains illegal characters, or if the string cannot be decoded as an integer value.
