Grouping column by DateTime

问题

I'd like to grouping a column by a DateTime field (Months)

The values of this field are how this: 2014-12-16T12:56:06.32+01:00

How should be the expression to make a primary group by column?

Best regards

回答1:

You can use this query :

select SUBSTR(COLUMN_NAME,6,2) as "MONTH",count(*) from TABLE_NAME group by 
substr(COLUMN_NAME,6,2);

You can add columns in group by as per requirement.

Note : Columns in group by should be present in select.

Group by the record in SSRS design .

In the group by record column expression ,give following query

=MonthName(Month(Fields!ListingDate.Value))
