MySQL Row Number: Simulate ROW_NOW()

In MySQL, there is no built-in ROW_NUMBER() function, but you can simulate it using user-defined variables. Here is an example:

SELECT 
    @row_number:=@row_number+1 AS row_number,
    column1,
    column2
FROM
    your_table
CROSS JOIN (SELECT @row_number:=0) AS t
ORDER BY column1;

In the example above, a user-defined variable @row_number is initialized by using CROSS JOIN (SELECT @row_number:=0) AS t, and it is then used in the SELECT statement to simulate row numbers. By incrementing @row_number by 1, row numbers are generated to mimic the functionality of the ROW_NUMBER() function. Finally, sorting the result set by a specific column ensures that the row numbers are generated in the desired order.
