I can add an 'set number of decimal places' option to ksqlite_add_column tool. 
But I need to fix displaying fixed decimal in forms.
Is this enough?

That's weird, as _you_ explicitely provide the column's type. For example, to 
add a 'price' column of double precision to 'cars' table, type:

./ksqlite_add_column db.kexi cars price Double
