Wild cards are used for pattern matching.
In oracle 2 wild cards are used .
%-----for zero or more characters
_------for 1 character only.

The LIKE condition allows you to use wildcards in the where clause of an SQL statement. This allows you to perform pattern matching. The LIKE condition can be used in any valid SQL statement - select, insert, update, or delete.

The patterns that you can choose from are:

% allows you to match any string of any length (including zero length)

_ allows you to match on a single character
