Re: Primary key in table
I use social security number as an example of what I thought would be a unique key and I get what you said about it but I just used it as an example.
Lets say I created a column in a Parent table called unique_field varchar(20) and I new the filed would be unique which would also be a data value that had a meaning
in the Parent Table
If I set this as the primary key is that a good practice or should I generate a
primary key and add unique_field as a UNIQUE KEY
