cube(name)我们知道其实就是grouping sets ((name), ()),当按(name)进行GroupBy时,能得到2个分组,分别为((2, Alice))和((5, Bob)),由于是按照name分组,name这一列是没有进行aggregate的,因此grouping(name)为0,也就是参与GroupBy的GroupByAttributes的grouping(attribute)一定为0,当按()进行GroupBy时,得到1...

If a select statement includes a where clause, but not a group by clause, an aggregate function produces a single value for the subset of rows, called a scalar aggregate. However, a select statement can also include a column in its select list (a Transact-SQL extension), that repeats the...

SQL reference Functions Aggregate functions GROUPING_ID GROUPING_IDConcatenates the set of Boolean values generated by the GROUPING function into a bit vector. GROUPING_ID treats the bit vector as a binary number and returns it as a base-10 value that identifies the grouping set combination....
I recently discovered that you cannot use standard aggregate or grouping SQL keywords (i.e. COUNT, GROUP BY, SUM) in data query functions within both ArcMap (as of
The examples in this section use the SUM aggregate function so that the result sets can be compared. The other aggregate functions might also be used to calculate different summaries. A. Using a simple GROUP BY In the following example, the simple GROUP BY returns a result set to compare to...
