Boolean operators (AND, OR, NOT) You can use these operators in your search strategy to help you search more accurately and effectively. To combine your search terms use the drop down boxes on the left of the s
C# logical operators perform logical negation (`!`), conjunction (AND - `&`, `&&`), and inclusive and exclusive disjunction (OR - `|`, `||`, `^`) operations with Boolean operands.

The AND, OR, and NOT keywords are PostgreSQL's Boolean operators. These keywords are mostly used to join or invert conditions in a SQL statement, specifically in the WHERE clause and the HAVING clause. The truth table of AND, OR, NOT operators ...
The binary AND and OR operators and the unary NOT operator have the usual semantics. Their operands are conditional expressions, which must have type BOOLEAN. An empty result from an operand is treated as the false value. If an operand returns NULL, then: The AND operator returns false if...

not has a lower priority than non-Boolean operators, so not a == b is interpreted as not (a == b), and a == not b is a syntax error.多复杂的组合表达式,最终都可以一重重拆解成一个个独立的小单元,在做合并就拿开头的引子来说Copydef enabled() -> bool: a = ["a,"b"] b = True...
