# | (Bitwise Inclusive OR) (SSIS Expression)

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

Performs a bitwise OR operation of two integer values. It compares each bit of its first operand to the corresponding bit of its second operand. If either bit is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to zero (0).

Both conditions must be a signed integer data type or both conditions must be an unsigned integer data 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 inclusive OR operation between the variables **NumberA** and **NumberB**. **NumberA** contains 3 (00000011) and **NumberB** contains 9 (00001001).

```
@NumberA | @NumberB
```

The expression evaluates to 11 (00001011).

00000011

00001001

-----------

00001011

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

```
ReorderPoint | SafetyStockLevel
```

If **ReorderPoint** is 10 and **SafetyStockLevel** is 8, the expression evaluates to 10 (00001010).

00001010

00001000

-----------

00001010

This example performs a bitwise inclusive OR operation between two integers.

```
3 | 5
```

The expression evaluates to 7 (00000111).

00000011

00000101

-----------

00000111
