Question : Can I complete a database row on insertion?

I currently have a table with 8 columns and I want to add another 2. The complication is that I would like to get the data for the other 2 columns from the database (using somekind of trigger, i guess) as the row is inserted.

My application sends:

INSERT(c1,c2,c3,c4,c5,c6,c7,c8)

With the idea being that the resulting insert is:

INSERT(c1,c2,c3,c4,c5,c6,c7,c8, F(c1), F(c2))

Where the functions (F) invloved retreiving values from the database based on the input value.

Any ideas?

Then try using

INSERT INTO urtable (c1,c2,c3,c4,c5,c6,c7,c8, c9, c10)
SELECT c1,c2,c3,c4,c5,c6,c7,c8, F(c1), F(c2)

Hope this helps
