Hello,

Could someone please tell how can data be updated (refreshed) in one table if the data is refreshed on another table and both tables are linked through a primary key - foreign key ?

I just need to know what logic I need to apply to update the values in a table if the same value has been refreshed in another table.

Thanks.

Without any more details about this I doubt anybody has much to offer. I think that what you are saying is that you have tablea and tableb. There is some column in tableb that is a foreign key to a column in tablea? Can you cascade updates and deletes on the foreign key? Or is your question because the update has already happened and now you want to fix the data in tableb?

I don't know that I would call that details but that certainly shows this is a duplicate thread.
