The ORDER BY clause identifies which columns to use to sort the resulting data, and in which direction to sort them (ascending or descending). Without an ORDER BY clause, the order of rows returned by an SQL query is undefined. The DISTINCT keyword [5] eliminates duplicate data.

In a numbered list in a large font, some browsers do not show more than two digits (2 spaces width) of indentation, unless extra indentation is applied (if there are multiple columns: for each column). This is fixed by increasing the default indentation of 3.2em by 2em more, and it can be done in multiple ways:
