A VIEW of all your columns
In this exercise you will create a new tool for finding the tables and columns you need. Using the system table information_schema.columns you will concatenate the list of each table's columns into a single entry.
Once you've done this you will make this query easily reusable by creating a new VIEW for it called table_columns.
