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 is 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 |
+-------------+
