Hi, I'm in the process of making a super simple database (3 - tables). I have run into a problem with two of the tables. The relationship between them is one -> many. Say, I have a record in the (one) table which contains a primary key that is also part of a compound primary key in the (many) table.
Ex:
tblEx1 - (1 side of relationship)
red(pk)
blue
yellow
etc...
tblEx2 - (many side of relationship)
red(pk)
purple(pk)
orange
etc...
If I create a record in tblEx1 and type in some BS for the "red(pk)" field, and I then go to tblEx2, fill in all the fields, and also type in the same BS for the
"red(pk)" field, and come back at a later date, and want to change the value of the "red(pk)" field in both those tables for a certain record, it will not allow me. It doesn't matter which one I go to first. Would I have to delete the relationship everytime to be able to change the value for the "red(pk)" field in either table?
On a related question. In the above example when your doing data entry I'm not sure if I'm doing this right. It seems odd to me that I would have to type in the field for "red(pk)" in both tables, isn't their a way it can automatically figure out to put the same value from the first table into the next one since thier in a relationship.
Sorry if the above is confusing, and stupid. I'm just asking cause I did a whole bunch of records and I have to modify the name of the field which is the primary key, and I don't want to have to delete all the records and re-enter them; that would be a big time waster. Any help is appreciated.
