There are a bunch of different tables in our zoo database.I'd like to just ha e the database tell you about them,but weirdly enough,there isn't one standard way to do that in SQL.If you want to know what tables are in a database,or what columns are in a table,well ,each database system supports doing that,but they all do it in different ways.And in most of them,you can't do any of these from your code itself,only from the database console,or special administrati e software.It's as if SQL was designed back in the days when you hand to plan out your whole application with flowcharts and stuff,before you were allowed to touch a computer and ask it any questions.So in order to sa e you a bunch of time and frustration,i' e put a list of all the tables in our zoo database,in the instructor notes below.
Maybe you can write a programe and change it??? and let people could control it in the python or any other language?????????
