Ref cursor is a cursor variable which acts as a pointer to
the sql memory area.
Ref cursor can be asssociated with multiple sql statements
where as a cursor can be associated with only one sql
statement.
Refcursor is dynamic where as cursor is static.
Ref cursors are of two types:
1)strong ref cursor:which retuns value.
2)week ref cursor:which doesn't return value.


thanks and regards

For the strong ref cursor the returning columns with
datatype and length need to be known at compile time.

For the weak ref cursor the structure does not need to be
known at compile time.

TYPE WEAK_REF_CURSOR IS REF CURSOR;

TYPE STRONG-_ REF_CURSOR IS REF CURSOR RETURN
TABLE_NAME%ROWTYPE;
