Regular Expressions

A regular expression is similar to a rule which defines the characters that can appear in an expression. In SQL databases, selecting field values based on regular expressions can be very useful. One example would be to validate credit card numbers or telephone numbers from a given database field. Another would be to check numeric values matching a particular sequence, such as integers containing the digits 99 or 88. SQL server database implementations provide built-in regular expression support.
