Depreciated Hints

Question

Hi Masters,
What are the hints which are depreciated in oralce 11g e.g bypass_ujvc ?
Though I know this hint is undocumented, Is there any document/url in which I can get all these.
Any help will be highly appreciated.
Regards

Answer 1

It exists in 11g onwards.
SQL> desc v$sql_hint
Name                                      Null?    Type
NAME                                               VARCHAR2(64)
SQL_FEATURE                                        VARCHAR2(64)
CLASS                                              VARCHAR2(64)
INVERSE                                            VARCHAR2(64)
TARGET_LEVEL                                       NUMBER
PROPERTY                                           NUMBER
VERSION                                            VARCHAR2(25)
VERSION_OUTLINE                                    VARCHAR2(25)
SQL> The view itself is not documented but nevertheless it is useful.
It doesn't tell you what is documented, what is undocumented, what is deprecated, not supported, etc.
It doesn't tell you the full syntax for a particular hint.
It does tell you what sql feature it relates to, gives a class and usefully the inverse of the hint.
It also tells you what version the hint was introduced in and version_outline is believed to indicate from which version the hint can be used in an outline.
There's no doubt that it's useful for the inquisitive.
You'll find that the hint PARALLEL is not listed but the hint SHARED is and SHARED is the inverse of NOPARALLEL/NO_PARALLEL, for example.
However SHARED is not documented, PARALLEL is.
The bottom line is that hints should be discouraged, particularly undocumented ones, the documented ones appearing in the documentation for the appropriate version, e.g. [url http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#autoId3]11gR2 SQL Language Reference.
