ISEMPTY() 参数展开表 术语定义 table_expression 表引用 or 返回表的 DAX 表达式。返回valueTrue if 表为空(无行),if 否则为 False。言论在计算列 or 行级别安全性 (RLS) 规则中使用时,not 支持在 DirectQuery 模式下使用此函数。例对于名为“Info”...
是否为空 */ @SuppressWarnings(“rawtypes”) public static boolean isEmpty(Object obj) { if (obj == null)...* * @param obj * 对象名 * @return 是否不为空 */ public static boolean isNotEmpty(Object obj) { return !...isEmpty(obj); } } 以上所述是小编给大家介绍的Java判断对象是否为...
ISEMPTY检查表是否为空。 ISERROR检查值是否为错误,并返回TRUE还是FALSE。 ISEVEN如果数字为偶数,则返回TRUE;如果数字为奇数,则返回FALSE。 ISFILTERED直接筛选TRUE时返回columnName。 ISINSCOPE当指定列是级别层次结构中的级别时,返回 true。 ISLOGICAL检查值是逻辑值(TRUE还是FALSE),并返回TRUE还是FALSE。
DAX includes many functions that return a table, rather than a value. The table is not displayed in a reporting client, but is used to provide input to other functions. For example, you can retrieve a table and then count the distinct values in it, or calculate dynamic sums across filtere...
the Insert Function dialog box. The Insert Function dialog box is the easiest way to get started entering a DAX formula. We’ll add a function to a formula when we create a measure a little later, but for now, you do not need to add a function to your calculated colu...
NOT Inverts the state of a Boolean expression (FALSE to TRUE, and vice versa).An example that uses the IN logical operator is the ANZ Revenue measure definition, which uses the CALCULATE DAX function to enforce a specific filter of two countries: Australia and New Zealand.Note...

The DAX formula is more powerful; moreover, by adding the ranking value to a Slicer, you can just click on the Slicer to change the number of top values that are displayed. However, the calculations are computationally expensive and this method might not be suited for tables with many rows...
