I have a database table containing for example 6 columns Column1,Column2,Column3,Column4,Column5 and Count. The Count column stores a count of Column1-5 that are not null. So if Columns1 and 3 are not null for a particular row it will store 2. I was wondering how can I go about writing a trigger that updates the count column whenever Columns 1 through 5 are updated.
Let me know if you need anything else from my end.
