Hello Everyone,

Here again I came with a question. Below is my query for a report that I want. It's working fine with no issues.

SELECT TP.Location, 
       TE.Name, 
       TEI.imp_amount_approved_by_finance AS Amount, 
       CONVERT(DATE, TEI.imp_fin_appr_date, 103) AS PaidDate
FROM tbl_emp_imprest TEI
     JOIN tbl_Projects TP ON TP.Sno = TEI.imp_emp_location
     JOIN tbl_Employee TE ON TE.Sno = TEI.imp_id
WHERE imp_amount_approved_by_finance > 0
      AND CAST(imp_fin_appr_date AS DATE) BETWEEN CAST('2021-01-01' AS DATE) AND CAST('2021-12-31' AS DATE)
GROUP BY TP.Location, 
         TE.Name, 
         TEI.imp_amount_approved_by_finance, 
         TEI.imp_fin_appr_date;

And the result of the above query as follows in the screen-shot

What I want is; that let's say for 1st row Location and Name( Agai-JSL , Barun Mondal) should come only once for repeated values and repeated values should replaced with blank values.

Kindly suggest.

Thanks

I almost always agree with Phil and Grant that this should be done at presentation time in whatever app is generating the final output.
But, then there's the human factors of not having anyone that actually knows how to do such things in the tool they're using to make the final output. A reasonable example of that is how to do it auto-magically in a spreadsheet. Another problem may be that you have no app to produce the final output other than what you can squirt out of SSMS into an email or whatever.
So... I'll make you an offer. It you change the output that you've posted as an otherwise unusable graphic into "readily consumable" data with a CREATE TABLE and INSERT/VALUES so I have a source table to demonstrate code with, I'll show ya how to do it. If you have no clue as to what I'm talking about, study the article at the first link in my signature line below.
Be advised that I'm NOT going to import data from a bloody spreadsheet or file to help you. Please post the data in the form I've asked for.

This sort of thing is best done in the report (ie, at presentation time) rather than in the query.

Yep. Formatting is best done in the client app. Always.

You didn't provide any sample data so I can't test this at all:

SELECT TP.Location, 
       TE.Name, 
       CASE WHEN LAG(Amount, 1) OVER(PARTITION BY TP.Location, TE.Name ORDER BY TEI.imp_fin_appr_date) = TEI.imp_amount_approved_by_finance
            THEN '' ELSE CAST(TEI.imp_amount_approved_by_finance AS varchar(20)) END AS Amount, 
       CONVERT(DATE, TEI.imp_fin_appr_date, 103) AS PaidDate
FROM tbl_emp_imprest TEI
     JOIN tbl_Projects TP ON TP.Sno = TEI.imp_emp_location
     JOIN tbl_Employee TE ON TE.Sno = TEI.imp_id
WHERE imp_amount_approved_by_finance > 0
      AND CAST(imp_fin_appr_date AS DATE) BETWEEN CAST('2021-01-01' AS DATE) AND CAST('2021-12-31' AS DATE)
GROUP BY TP.Location, 
         TE.Name, 
         TEI.imp_fin_appr_date,
         TEI.imp_amount_approved_by_finance
ORDER BY TP.Location, 
         TE.Name, 
         TEI.imp_fin_appr_date;
