setting CURSOR_SHARING can significantly improve cursor sharing, resulting in reduced memory usage, faster parses, and reduced latch contention. Consider this approach when statements in the shared pool differ only in the values of literals, and when response time is poor because of a very high ...
Usage notes This procedure can be invoked using function invocation syntax in a PL/SQL assignment statement. Examples Example 1:The following example creates a new cursor: DECLARE curid INTEGER; BEGIN curid := DBMS_SQL.OPEN_CURSOR; . . . END;...
