Sorry if this post needs to be in the sql group.

I am trying to update bunch of records in the same table with a value from one of those records.

I have n records of which i have x that have blank ssnumber.
These x records belong to multiple categories.

I need to be able to update group x records category "A" with values from x records (there should be a record in each group that has a valid value to populate the others)

And the same applies for the other categories.

I can select * from table order by category and then the value. Then i can have a loop to pick and update each one. I do not think this is efficient.

Is there a better way to handle this? I started brain storming but i could not glow it together.

I user a select * from ... order by category, value DESC
then I used filtering
then I used update... that’s when I lost it.

If I use Group by on filtering to update a whole bunch of records per category.... would this work... how?


Thanks in advance..
Quan
