2 Solution mysql can do that for you. 3 Discussion mysql generates result set output as HTML tables if you use -H (or --html) option.  Here's an example that shows the difference between tabular format and HTML table output (a few line breaks have been added to the HTML output to make it easier to read):  I'm referring to writing static HTML pages here. If you're writing a script that produces web pages on the fly, there are better ways to generate HTML output from a query. For more information on writing web scripts, see Chapter 16.
Otherwise, you can hit Tab again to see the possible matches. • Enter additional characters and hit Tab again once to complete it or twice to see the new set of matches. mysql's name auto-completion capability is based on the table names in the current database, and thus is unavailable within a mysql session until a database has been selected, either on the command line or by means of a USE statement.
