Introduction to Databases for Web Developers
As in most languages, SQL provides a set of wildcards that are used as shortcuts to represent whole categories of values. For example, oftentimes, you may want all the data for the columns in your table but you don't want to write all the column names in a comma-delimited list.

To make such queries more efficient, SQL provides the "*" wildcard that specifies "ALL" of something. For example, to select all the columns in the PRODUCTS table, we would use:

     SELECT *

The database would then respond with:

001	104		99.99
002	12		865.99
003	2000    	50.00
