ALTER TABLE DDL Triggers?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I don't believe that DDL Triggers exist, correct?  Actually I am
really curious about what options exist to automatically keep table
definitions in sink (for two table) over time: for example a table and
history table pair.

I realise that History-Entity-Attribute-Value tables don't need this
kind of maintenance, but I am depending on the ability to frequently
query the history tables for the previous values of a particular
record.  I don't believe that History-EAV tables can do this.
