Describes boolean operators and logical expressions 讨论布尔运算符和逻辑表达式。
Choose the boolean operator to use to combine this expression with the expression in the next row 和/或选择布尔运算符将此表达式与下一行中的表达式组合使用。
A command in the work item query builder that enables you to join query two clauses with a boolean operator 工作项查询生成器中的命令,通过它可以使用布尔运算符联合两个查询子句。

The colors of the brush currently selected in the destination device context are combined with the colors of the inverted source area using the boolean 将目标设备上下文中当前选定的画笔颜色与已逆转的源区域的颜色组合。使用布尔运算符
You can create a simple constraint expression to check data for a simple condition ; or you can create a complex expression , using boolean operators , to check data for several conditions 可创建简单的约束表达式,用简单条件检查数据或者使用布尔运算符创建复杂表达式,用若干个条件检查数据。
Because by default , fs is set to a single space character , which awk interprets to mean " one or more spaces or tabs . " in this particular example , the default fs setting was exactly what you wanted in the first place 而且,如果想要查看是否存在某个特定数组元素,可以使用特殊的" in "布尔运算符,如下所示:
While a predefined action only permits subscribers to specify parameter values for developer - defined queries , a condition action allows a subscriber to create the equivalent of a where clause for the query , using boolean operators and , or , and not to combine individual conditions 预定义操作仅允许订阅方为开发人员定义的查询指定参数值,而条件操作则允许订阅方通过使用布尔运算符( and 、 or和not )组合各个条件,为查询创建等效的where子句。
