Global Hints
December 20, 2010 Leave a comment
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.) |
