Text Handling

SQL has extensive text-handling capabilities built in. You can extract parts of a string using the standard functions. The basic operators, such as LIKE and || or CONCAT (concatenation), are all that you need for everyday queries. But there are some more exotic facilities, such as full-text indexing and string hashing, that can make your code faster and smarter.
