Re-establishing Existing Relationship

Re-establishing Existing Relationship

Re-establishing Existing Relationship


 I'm trying to change data  in a table that has a one to many relationship with about 15 other tables.   The problem is, I can't change data in the master table because of the  preexisting relationship that already exists.  Is there a way to  temporarily remove an existing relationship, change the data you want, and then  reestablish it later without destroying or losing data?  Another challenge  I'm facing is the fact that since I didn't design the database, I have to be careful of what I change since there is little to no documentation.

Thank you for your imput,


RE: Re-establishing Existing Relationship

If the relationship on the table has Cascade Update Related Fields checked in the join within the relationship window you can change the data in the master table and Access will "automagically" update every record in every table related to the master.  Make sure you backup your database before trying this!

And just to add to that... The thing that gets the cascading update is the primary key value. This won't work if the primary key is an autonumber. Let us know if this is not what you needed!
