I want to set a default value in a field in a table, lets call it table A. The default value has to come from another table, lets call it table B. The value from table B should be from a row corresponding to a foreign key in table A. Example: In table A there is a field call Stock#, this is a foreing key to table B, where stock# is primary key. In table B there are all the informations about the stock, that is quantity, price etc. When I key values in table A, and keys a value in the Stock# field, I want the price from table B showing for this Stock#. Perhaps the question looks easy, but I have tried many things without succeding yet. Can you help me as how to write in table design for table A the function to use to set the default value from table B? Thank you.
