Typo on Page 19
On the page 19 there are a couple of SQL statements with typos in them.
For example:
SELECT title
, author
, author2
) FROM myLibrary;
The parenthesis is a type and should be removed. Otherwise, the RDBMS would throw an error when trying to execute the command.
For example, Microsoft SQL server will display the following message:
Msg 102, Level 15, State 1, Line 9
Incorrect syntax near ')'.
