In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The count(bid) function returns 1, while the count(*) function will return 3."

A block of code is set as follows:

test=# INSERT INTO t_test SELECT 10, 20, 30,
  'abcd', 'abcd', 'abcd'
  FROM generate_series(1, 10000000);
INSERT 0 10000000

Any command-line input or output is written as follows:

SELECT * FROM website WHERE domain = 'www.cybertec.at';
