& (Bitwise AND) (SSIS Expressions)

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.

integer_expression1 & integer_expression2
integer_expression1, integer_expression2

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

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

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

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

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).

This example performs a bitwise AND operation between two integers.

3 & 5 

The expression evaluates to 1(00000001).

00000011

00000101
