You can have in a where clause a varchar2 column compared to a number column , if the varchar2 column only contains numeric then it will work.

There is a view here that produces an error, I identified why -- in one AND clause a number(9) datatype column is being joined with a varchar2(50) datatype column. The developer of this code says that this used to run, there must be something wrong with the server. I want to verify... Is there any kind of overloading invoked automatically when Oracle compares columns of different datatypes? i.e. if the varchar2(50) column only contains numbers, would Oracle convert it automatically to number before making the comparison?
