    Trigger on a Table

    Hi,

    I am looking at to know if any changes are made to a table on the database. We pull the Oracle table and load it in the mysql database. The oracle table is updated once in a while. Now what I do is refresh the data on mysql everyday and compare the cahgnes.

    So is there any in built trigger or something which notifies me whenever a change is made in the table. Like shooting an email or something like that..so that I can pull the table to the mysql.

    Thanks

    This looks like human-driven replication, interesting concept
