Hello Experts

Consider this table result:

Message_ID   Contact_ID
------------------------
    1            2
    2            5
    2            1
    1            2
    2            1

Now I want the below view:

Message_ID    TotalSent
------------------------
    1            2
    2            3

How can I achieve this goal?

Thank you for your help.

Try:

SQL

SELECT Message_ID, COUNT(Message_ID) AS TotalSent FROM myTable
GROUP BY Message_ID

Thank you for your time.
What if I want to get the message content from the table 'Message' using inner join and also other columns from the current table?

The error message:
Column 'column1' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

What's the query you are using?

The below query gave me this:

Title Content RowNumber ID
----------------------------------------------------
first firstContent 1 1
first firstContent 2 4
first firstContent 3 5
second secondContent 1 9
second secondContent 2 2

But I need this:

Title Content Count
-------------------------------------------
first firstContent 3
second secondContent 2

In fact I used row_number to get the maximum of it for each message.

With CTE As
( Select Row_Number() Over(Partition By [Log].Message_ID Order By [Log].ID) As RowNumber,
Message.Title,
Message.Content,
[Log].ID
From [Log]
Left Outer Join
Message
On Message.ID = [Log].Message_ID
) Select Title,
Content,
RowNumber,
ID
From CTE As A
