Solved: Hello, I have a small dilema around AND OR boolean operators. I dont want null time logs for event=timeOut, but at the same time I also want

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 search screen. And will include both search terms in your results ...
逻辑布尔运算符使用bool操作数执行逻辑运算。 运算符包括一元逻辑非 (!)、二元逻辑 AND (&)、OR (|) 以及异或 (^),二元条件逻辑 AND (&&) 和 OR (||)。 一元!(逻辑非)运算符。 二元&(逻辑与)、|(逻辑或)和^(逻辑异或)运算符。 这些运算符始终计算两个操作数。
C# logical operators perform logical negation (`!`), conjunction (AND - `&`, `&&`), and inclusive and exclusive disjunction (OR - `|`, `||`, `^`) operations with Boolean operands.
You might occasionally want to combine test expressions to evaluate multiple conditions in one if, elif, or else statement. In this case, you'd use the Boolean operators and and or.The or operatorYou can connect two Boolean, or test, expressions by using the Boolean or operator. For ...
如果使用多个布尔运算符,那么将按照从左到右的顺序对这些运算符进行求值。但是,与常规布尔逻辑一样,逻辑运算符 AND(&)优先于逻辑运算符 OR(|)。可以在以下示例中了解此求值,它不包括圆括号: "book" & "pulitzer"| "year" & "author" Net Search Extender 按以下方式对布尔运算符进行求值: ...

The & operator will perform a Boolean And operation when one or more input (operand) is a raster. If both inputs (operands) are numbers, then the & operator will perform Bitwise And operation. For more information on how to work with operators, see Working with operators. Wenn ein Ausdruc...
Therefore, when Boolean operators are used in the same expression as Relational operators, the Boolean operators will be executed first. To change the order of execution, use parentheses. When multiple Relational and/or Boolean operators are used consecutively in a single expression, in some cases,...
