Question

I have to use GROUP BY statement to pull data from SQL Server CE.

Now I’m getting

In aggregate and grouping expressions, the SELECT clause can contain
only aggregates and grouping expressions. [ Select clause = ,Date ]

but I really want to get date.

Query is as follows

SELECT Date 
FROM Installments 
GROUP BY ID 
HAVING Sr = max(Sr)

What am I doing wrong? Please explain

Answer 1

When you use group by, you group by some field, and apply an aggregate function.
So, in the select, you shoud that field (the grouped result) and then the result of the function used.

Maybe you want something like

SELECT Id, Max(date) FROM Installments GROUP BY ID 

It will depends on what you want.
