SQL Aliases
SQL aliases are used to give a table, or a column in a table, a temporary name.
Aliases are often used to make column names more readable.
An alias only exists for the duration of the query.
Aliases can be useful when:
There are more than one table involved in a query
Functions are used in the query
Column names are big or not very readable
Two or more columns are combined together
