Is there any way to use ROW_NUMBER() in SQL without using OVER, because I want to use sorting.
I have a Grid with multiple sortable columns with configurable rows. In my scenario order by is variable that's why I am not able to put order by using ROWNUM.

The row_number() window function can be used without order by in over to arbitrarily assign a unique value to each row.
ROW_NUMBER() Function without Partition By clausePartition by clause is an optional part of Row_Number function and if you don't use it all the records of the result-set will be considered as a part of single record group or a single partition and then ranking functions are applied.
ROW_NUMBER function is a SQL ranking function that assigns a sequential rank number to each new record in a partition. When the SQL Server ROW NUMBER function detects two identical values in the same partition, it assigns different rank numbers to both.
This example sequentially numbers each row, but does not order them. Because the ROW_NUMBER function requires an ORDER BY clause, the ROW_NUMBER function specifies ORDER BY (SELECT 1) to return the rows in the order in which they are stored in the specified table and sequentially number them, starting from 1.
