I have data like this

id	name
1	AA
2	BB
3	CC
4	DD
5	EE

Given that, I have to use a select statement like this.

select *
from (
  select
    row_number() over (partition by id order by id asc) as row
    , id
    , name
) tmp
where tmp.id in (2,3,4) -- Just an example of condition in outer query

I could not temper with outer query [tmp] selection. when I want display data to be as

row	id	name
1	2	BB
2	3	CC
3	4	DD

Is there any way to achieve row_number() as intended without creating temp table and use store procedure to delete and insert every time it queries data with some condition.

The best case I could find for now is using a new temporary table for the results wanted it to be and a stored procedure to truncate and insert it as conditions specified

BEGIN TRY   
            TRUNCATE TABLE [TEMP]
            IF EXISTS (SELECT 1 FROM MAIN WHERE your condition)
            SELECT @TableName = 'MAIN'
            , @Condition = 'your condition'
            ELSE
            SELECT @TableName = 'MAIN'
            , @Condition = ' '
           
            SELECT @sqlCommand = 'INSERT INTO TEMP select 
               row_number() over (partition by id order by id asc) as row ,
              /**other columns**/
                from '+@TableName
                +@Condition
            EXEC (@sqlCommand)

            
            SET @o_MSG = 'OK';
        COMMIT;
        END TRY                         
        BEGIN CATCH
            ROLLBACK;   
            SET @o_MSG = 'ERROR';
        END CATCH
