Thank youhi guys, if im going to create a table with derived column(meaning it's value is automatically created based from the value of another column from the table).

for example i have a base column named birth_date and the derive column is age (where age is automatically computed based on the value entered in the birth_date).

is there a way where in i can do this in the create table clause? Hi, I'm busy creating a database for store staff which will be managed by a web page written in PHP.

My question is if I have the following columns in the table: Branch_Code, Name, Password, Position, Menu_Level I want to create templates for say Managers, Admin Managers, Front line Managers, Cashiers, Dispatch and Receiving etc and all these will have different Menu_levels, Auth_Levels and Stores.

How will I go about using information from the templates to create a new user without overwriting the original template?

Is there a way that I can duplicate the required row, insert the the correct info i.e. so can u suggest v gud book which is free in downloading and tel best site where v can find various examples on queries.
