Hi Friends,

I have used row count transformation to get the row count as final column but the row count populates in all the columns.

e.g. My file should look like this

A B C RowCnt
x y z NULL
g h i NULL
k l m 3

The "3" in the "RowCnt" column says the total number of records.

I achieved this :(

A B C RowCnt
x y z 3
g h i 3
k l m 3

I am stuck with this. Please help me in achieving the first result.

Thanks in advance.

You can do something like -

SQL

SELECT A,B,C
,CASE WHEN ROW_NUMBER() OVER(ORDER BY A,B,C)=(SELECT COUNT(*) FROM dbo.YourTable)
      THEN (SELECT COUNT(*) FROM dbo.YourTable)
      ELSE NULL END AS RowCnt
FROM dbo.YourTable

If this doesn't help, please share the sql you have tried so far to get the o/p as shown in the question.

Hope, it helps :)
