My 5 as this does exactly what the OP asked for (but no more).

Solution 2

SQL

SELECT *
FROM OpeningsBalance
WHERE TrnsNo in(select TrnsNo from OpeningsBalance where Customername='TESTT');

Reason for my downvote ... OP requires maximum TrnsNo and Customername = 'Kiran', and the structure of your SQL is poor and inefficient. If you have two customers with a TrnsNo of say '5' then you will get the data for both customers instead of just TESTT.

The Same trnsNo will not repeat because its auto generate no

Fair enough - although that wasn't mentioned. However your SQL could therefore be simplified to SELECT * FROM OpeningsBalance Where Customername = 'TESTT' which still does not fit the requirement. SELECT TOP 1 * FROM OpeningsBalance Where Customername = 'kiran' ORDER BY TrnsNo would be tidier
