Performs a logical conjunction on two expressions.
result = expression1 And expression2
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 |
