设计应用时,如果能有效地使用和应用“true”和“false”概念,您便可以生成更优质的整体应用。 如果使用If函数评估应用中的条件,其结果要么为true,要么为false。 举个例子,上一单元中,我们在“Retake Test”按钮的Visible属性中使用了以下公式: If(ThisItem.TestScore = "A" or ThisItem.TestScore = "B", ...

在上面的示例中,condition是一个逻辑表达式,可以使用比较运算符(如等于、大于、小于等)和逻辑运算符(如AND、OR、NOT)来构建。根据condition的结果,查询将返回TRUE或FALSE。 TSQL转换查询以返回TRUE/FALSE的应用场景包括: 数据验证:可以使用TSQL查询来验证数据的有效性,例如检查某个字段是否满足特定条件。
The bool type has two possible values: true or false. Boolean values are used widely in conditional expressions. If a bool statement or value is true, then do this action; otherwise (the statement or value is false), do a different action. A boolean value is often returned by a ...
