MySQL BIT_AND is one of the Aggregate Function, which performs Bitwise AND operation on all bits. This MySQL BIT_AND function first converts all decimal values into binary values, and perform bitwise and operation on those binary values.

## MySQL BIT_AND Syntax

The basic syntax of the BIT_AND Function in MySQL is as shown below:

SELECT BIT_AND (Expression) FROM [Source]

The Truth Table behind this Bit_And function is

x | y | x BIT_AND y |
---|---|---|

0 | 0 | 0 |

0 | 1 | 0 |

1 | 0 | 0 |

1 | 1 | 1 |

## MySQL BIT_AND Function Example 1

In this example, we are going to implement the BIT_AND function on different columns in a table. To demonstrate the same, we are going to use the dup employee 2 table data that we have shown below

The following MySQL statement finds the Bitwise AND values of Sales 1 and Sales 2 columns.

-- MySQL BIT_AND Function Example USE company; SELECT BIT_AND(Sales1), BIT_AND(Sales2) FROM dupemploy2;

**OUTPUT**

x = 9 = 1001

y = 12 = 1100

and the Bitwise AND for the above bits is 1000 = 8

## MySQL BIT_AND Group By Example

In this example, we are going to use the BIT_AND function along with the Group By clause. For this, We are going to use the below shown data

**CODE**

-- MySQL Aggregate BIT_AND Function Example SELECT Profession, Yearly_Income ,bit_and(Yearly_Income) FROM company.dupcustomerdetails group by Profession;

**OUTPUT**

Let me take the Example for Developer Group

85000 = 10100110000001000

80000 = 10011100010000000

55000 = 01101011011011000

and the output is 0
