For example, if you wanted to see all subjects in alphabetical order, you would use the following query: SELECT subject FROM subjects ORDER BY subject You can also order by multiple fields. For example, to print out an alphabetical list of patrons, you could use this one: SELECT * FROM patrons ORDER BY last_name, first_name The result of this search would be the entire contents of the patrons table, ordered by last_name and, within last_name, by first_name.

For example, the following two (equivalent) searches will retrieve records where France (but not france) is in the title field: SELECT * FROM books WHERE BINARY title LIKE '%France%' SELECT * FROM books WHERE title LIKE BINARY '%France%' Just as command line searching in OPACs, SQL does enable you to provide multiple conditions with its Boolean operators AND and OR.
