developer came by and asked me an interesting question. If he has a view with 20 columns in it, and he selects a specific column from the view in his query. Does the engine when accessing the view return all columns? or is it smart enough to know to just retrive the one? example: create view test as select a,b,c,d,e,f,g from testtable; select a from test; (does the engine retrieve b-g?)
