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 is convenient to represent `VARBINARY`

, `BINARY`

or `BIT`

values.

To convert a binary literal into an integer, just add 0.

Printing the value as a binary string:

SELECT 0b1000001; +-----------+ | 0b1000001 | +-----------+ | A | +-----------+

Converting the same value into a number:

SELECT 0b1000001+0; +-------------+ | 0b1000001+0 | +-------------+ | 65 | +-------------+
