I have a table

MissingData

1
10
NULL
NULL
22
NULL

The desired output will be

MissingData

1
10
10
10
22
22

i.e. the nulls will be filled up by the previous value until a new value is appearing.

I can solve this by using loop but my requirement is to solve it by CTE in which I am not so comfortable as of now.

Thanks
