Question

I have the following table schema:

create table SerialNo2( IncarnationID_UID counter primary key, Mark integer ); 

Now I want to add a new column in the table, let’s call it degree. Given that I want to apply an update on production table, I will have to populate the degree column based on the Mark value for all the existing data in the SerialNo2 table. The rule for this is that

if Mark>90 then degree='A', else degree='B' 

How to write a conditional SQL insert that will accomplish the above function?

Answer 1

Something like this:

UPDATE SerialNo2 SET SerialNo2.Degree = IIf([Mark]>90,'A','B')
