AND          -                         The AND operator allows the existence                                               of  multiple conditions in an SQL                                                           statement's WHERE clause.


ANY         -                          The ANY operator is used to compare a value to any applicable value in the                                                 list  according to the condition.

BETWEEN   -                       The BETWEEN operator is used to search for values that are within a set of                                                 values, given the minimum value and the maximum value.

EXISTS   -                            The EXISTS operator is used to search for the presence of a row in a                                                           specified table that meets certain criteria.
