Logical Operators (Transact-SQL)
https://docs.microsoft.com/en-us/sql/t-sql/language-elements/logical-operators-transact-sql
Logical operators test for the truth of some condition. Logical operators, like comparison operators, return a Boolean data type with a value of TRUE, FALSE, or UNKNOWN.
Operator | Meaning |
---|---|
ALL | TRUE if all of a set of comparisons are TRUE. |
AND | TRUE if both Boolean expressions are TRUE. |
ANY | TRUE if any one of a set of comparisons are TRUE. |
BETWEEN | TRUE if the operand is within a range. |
EXISTS | TRUE if a subquery contains any rows. |
IN | TRUE if the operand is equal to one of a list of expressions. |
LIKE | TRUE if the operand matches a pattern. |
NOT | Reverses the value of any other Boolean operator. |
OR | TRUE if either Boolean expression is TRUE. |
SOME | TRUE if some of a set of comparisons are TRUE. |
