Hi List,
I don't understand when one must use ANY, SOME or ALL
I don't understand the use of the use of this optoins
I suppose they were added only to give more SQL ansi compatibility
SELECT USR_NOMSIS FROM UTL_USUARIO_SIS WHERE PER_CI = ALL (SELECT -2354 FROM
UTL_USUARIO_SIS WHERE 1=0)
ORDER BY 1
ANY
SOME

a list or returned by a query. Must
be preceded by =, !=, >, <, <=, >=.

WHERE department_id = 30);
ALL Compares a value to every value
in a list or returned by a query.
