int SET_EQUAL(sessionID, set_id_exp1, set_id_exp2)
Set comparison between sets set_id_exp1 and set_id_exp2. If the sets are
equal returns TRUE else returns FALSE.
int SET_DISJOINT(sessionID, set_id_exp1, set_id_exp2)
Set comparison between sets set_id_exp1 and set_id_exp2. If the sets are
disjoint returns TRUE else returns FALSE.
6.3.3.2 Expressions returning an integer value
Functions that are used in logical expressions and return an integer value are the
following:
int VAL(sessionID, int_val)
The integer value int_val passed as argument.
int CARD(sessionID, set_id_expr)
The cardinality of set set_id_exp (Section 6.3.3.4).
6.3.3.3 Expressions returning a system identifier
Functions that are used in logical expressions and describe an object are the
following:
int SYS_ID(int sessionID, int sysid)
The object with system identifier sysid.
int NODE(int sessionID, l_name nodename)
The node object with unique logical name nodename.
int LINK(int sessionID, l_name fromcls, l_name linkname)
The link object with logical name linkname that points from node object with
unique logical name fromcls.
6.3.3.4 Expressions returning a set identifier
Functions that are used in logical expressions and return a set identifier are the
following:
int SET_ID(sessionID, setid)
The object with set identifier setid. If setid is 0 means the object the condition
is evaluated for.
int SET_UNION(sessionID, set_id_expr1, set_id_expr2)
Set union between set described by set_id_expr1 and set described by
set_id_expr2. If the two sets are tuples the union is performed to the tuples
(provided they have the same number of columns).
