Global Hints

Oracle hints just refer to the table in the query. But there exist GLOBAL HINTS which allows you specify hints for a table within a view.

For example hint index:

SELECT /*+ index(v_standart_struct.ss indx_name) */col1,
col2,
col3 - 15,
col4
FROM v_standard_struct
WHERE col1= 910
AND col2 = 2
ORDER BY col4;
Note: I have written “.ss”-> alias of the table within a view, not the actual name. When table has alias, you must use it. If you forget it and write the actual name of the table, but not alias, it will not work.(If table doesn’t have an alias,you must use the actual name.)
