And Operator
Performs a logical conjunction on two expressions.
result = expression1 And expression2
Arguments
result
Any numeric variable.
expression1
Any expression.
expression2
Any expression.
Remarks
If, and only if, both expressions evaluate to True, result is
True. If either expression evaluates to False, result is
False. The following table illustrates how result is
determined:
| If expression1 is | And expression2 is | The result is | | True | True | True | | True | False | False | | True | Null | Null | | False | True | False | | False | False | False | | False | Null | False | | Null | True | Null | | Null | False | False | | Null | Null | Null |
The And operator also performs a bitwise comparison of identically
positioned bits in two numeric expressions and sets the corresponding bit in result according to the
following table:
| If bit in expression1 is | And bit in expression2 is | The result is | | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 | |
