Is there a benefit to having a single column primary key vs a composite primary key?
I have a table that consists of two id columns which together make up the primary key.
Are there any disadvantages to this? Is there a compelling reason for me to throw in a third column that would be unique on it’s own?
Database Normalization nuts will tell you one thing.
I’m just going to offer my own opinion of what i’ve learned over the years..I stick an AutoIncrementing ID field to Every ($&(@#$)# one of my tables. It makes life a million times easier in the long run to be able to single out with impunity a single row.
