I think the O'Reilly books
- Managing and Using MySQL
- MySQL and mSQL

I feel like I am probly being amazingly stupid, but here goes nothing.
I have 3 tables:
"students"
"undergrads"
"postgrads"
"students" holds all common info. eg dt_matric, dob, religion, etc.
undergrads hold eg. degree, subject
postgrads holds eg. transfer_dat

Hi,
I am having trouble finding differences.
Table1 holds the current data, and Table2 holds the updates.
I need to query the two and find ONLY the rows showing the current+updates.

Hi,
I am trying to speed things up a bit by indexing, but am having a bit of

has_desc enum('T','F') NOT NULL default 'F'

Hope you don't mind me hassling you about this yet again.
