# ^ (Bitwise Exclusive OR) (SSIS Expression)

**SQL Server 2008 R2**

Performs a bitwise exclusive OR operation of two integer values. It compares each bit of its first operand to the corresponding bit of its second operand. If one bit is 0 and the other bit is 1, the corresponding result bit is set to 1. If both bits are 0 or both bits are 1, the corresponding result bit is set to 0.

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

Determined by data types of the two arguments. For more information, see Implicit Data Type Conversion in Expressions.

This example performs a bitwise exclusive OR operation between variables **NumberA** and **NumberB**. **NumberA** contains 3 (00000011) and **NumberB** contains 7 (00000111).

@NumberA ^ @NumberB

The expression evaluates to 4 (00000100).

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

ReorderPoint ^ SafetyStockLevel

If **ReorderPoint** is 10 and **SafetyStockLevel** is 8, the expression evaluates to 2 (00000010).
