select 'D05503'+ROW_NUMBER() OVER(ORDER BY C_CODE),* from Tbl_Doc_Stock_Chem_Add_Mst where N_Type=1 and C_Code like 'sa%'

While executing this query am getting error
like below:

Error converting data type varchar to bigint.

Numbers should come like this:

That's a pretty cryptic error message.
But it probably comes from doing things in the wrong order.
Analytic functions are last in the pipe.

So try using a CTE like this:

SQL

WITH CTE AS (
    SELECT  ROW_NUMBER() OVER(ORDER BY C_CODE) rn
    FROM    Tbl_Doc_Stock_Chem_Add_Mst
    WHERE   N_Type=1
        AND C_Code LIKE 'sa%'
    )
SELECT  'D05503' + cast(rn as varchar) Somenumber
FROM    CTE

ROW_NUMBER returns a numeric value, and SQL is trying to convert the text string "D05503" to a number in order to add it. That won't work.
Instead, try this:

SQL

SELECT 'D' + RIGHT('00000' + CONVERT(VARCHAR, 5503 + ROW_NUMBER() OVER (ORDER BY C_CODE)), 5), * 
FROM bl_Doc_Stock_Chem_Add_Mst 
WHERE N_Type=1 AND C_Code LIKE 'sa%'

5+. But OP's required output is starting from D05503. So i think have to change "VARCHAR, 5503" to "VARCHAR, 5502".

:laugh: Easy to fix!
I copied from the OP original and modified from there - so it does what his tried to do.
