Binary Literals
Binary literals can be written in one of the following formats: b'value'
, B'value'
or 0bvalue
, where value
is a string composed by 0
and 1
digits.
Binary literals are interpreted as binary strings, and are convenient to represent VARBINARY, BINARY or BIT values.
To convert a binary literal into an integer, just add 0.
Examples
Printing the value as a binary string:
SELECT 0b1000001; +-----------+ | 0b1000001 | +-----------+ | A | +-----------+
Converting the same value into a number:
SELECT 0b1000001+0; +-------------+ | 0b1000001+0 | +-------------+ | 65 | +-------------+
