# & (Bitwise AND) (SSIS Expression)

**APPLIES TO:** SQL Server, including on Linux Azure SQL Database Azure Synapse Analytics (SQL DW) Parallel Data Warehouse

Performs a bitwise AND operation of two integer values. It compares each bit of its first operand to the corresponding bit of its second operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0.

Both conditions must be a signed integer type or both conditions must be an unsigned integer type.

## Syntax

```
integer_expression1 & integer_expression2
```

## Arguments

*integer_expression1, integer_expression2*

Is any valid expression of a signed or unsigned integer data type. For more information, see Integration Services Data Types.

## Result Types

Determined by data types of the two arguments. For more information, see Integration Services Data Types in Expressions.

## Remarks

If either condition is null, the expression result is null.

## Expression Examples

This example performs a bitwise AND operation between the columns **NumberA** and **NumberB**. **NumberA** contains 3 (0000011) and column **NumberB** contains 7 (00000111).

```
NumberA & NumberB
```

The expression evaluates to 3 (00000011).

00000011

00000111

-----------

00000011

This example performs a bitwise AND operation between the **ReorderPoint** and **SafetyStockLevel** columns.

```
ReorderPoint & SafetyStockLevel
```

If **ReorderPoint** is 10 and **SafetyStockLevel** is 8, the expression evaluates to 8 (00001000).

00001010

00001000

-----------

00001000

This example performs a bitwise AND operation between two integers.

```
3 & 5
```

The expression evaluates to 1(00000001).

00000011

00000101

-----------

00000001
