I am totally new to SQL and am trying to do a simple DB.

What I would like to do is have a main table that contains all the information, than a second table that is auto populated when a new record is added to table 1 using triggers.

Then in the second table I would like to coconate two fields of different data types. I.e name and phone number.

Would anyone have any ideas how to go about this?

Thanks in advance

Triggers are available in MySQL beginning with MySQL 5.0.2. For an ample explanation on this subject I have to direct you to the MySQL documentation. They can explain it much better then I can. Look at Using MySQL triggers
