[SOLVED] Run this query without changing the sql

Run this query without changing the sql_mode

I am trying to test a query in test environment which is as follows

Query : -

 SELECT a.aggreatorid AS aggreatorid, '' AS txndesc, DATE_FORMAT(DATE(b.txndate),'%d/%m/%Y') AS txndate,
  SUM(txncredit) AS txncredit, SUM(txndebit) AS txndebit  
  FROM  walletmast a INNER JOIN wallettransaction b ON a.walletid=b.walletid  
  AND txndate  BETWEEN CURDATE() - INTERVAL 3 DAY AND CURDATE()  
  GROUP BY a.aggreatorid, DATE(b.txndate)
  ORDER BY txndate DESC

The query is throwing following

Error : -

SQL Error (1055): 'digitalpurse.b.txnDate' isn't in GROUP BY

The query works on my local environment but not on test environment after a lot of searching I found that the test environment has sql_modes which can not be changed for application flow and security purpose

SQL Mode : -

 @@sql_mode                                                                                                                                |

Is there a way to run this query without changing the sql_mode? Let me know if any other information is requried. Thank you in advance :D

Solution

Move the query into a subquery that selects DATE(b.txndate), so that it matches the GROUP BY clause, and then perform the formatting in the main query.

SELECT aggreatorid, '' AS txndesc, DATE_FORMAT(txndate, '%d/%m/%Y') AS txndate,
    txncredit, txndebt
FROM (
    SELECT a.aggreatorid AS aggreatorid, DATE(b.txndate) AS txndate,
        SUM(txncredit) AS txncredit, SUM(txndebit) AS txndebit  
    FROM  walletmast a 
    INNER JOIN wallettransaction b ON a.walletid=b.walletid  
    WHERE txndate BETWEEN CURDATE() - INTERVAL 3 DAY AND CURDATE()  
    GROUP BY a.aggreatorid, DATE(b.txndate)
) AS x
ORDER BY txndate DESC
