   expr LIKE pat [ESCAPE 'escape-char']
Pattern matching using
SQL simple regular expression comparison. Returns 1 (TRUE) or 0
(FALSE).  If either expr or pat is NULL, the result is
NULL.

The pattern need not be a literal string. For example, it can be specified
as a string expression or table column.

With LIKE you can use the following two wildcard characters
in the pattern:

     Character 	 Description
   % 	 Matches any number of characters, even zero characters
   _ 	 Matches exactly one character
