I worked for a company, that shall remain unnamed, that had specific database naming standards. The standards were strict, as they should be, and I stayed with the company
over four almost five years and the naming conventions are now immersed in my SQL conscience.
For example all tables in the database had to be prefixed with a 't' (Why? no one knew but we did it, and there was very little benefit in changing it), so I would begin every SQL select with: "select * from tWhatever"
This is wonderful and harmless until I came to my new place of work in which I do not have to worry about the 't' or the 'idb' or anything else like that. Unfortunately my fingers just cannot seem to break the habit and 'select * from' does not seem complete without the 't'.
