Question: I added an index hint in my query,but the hint is being ignored. What is the correct Syntax for an index hint and how do I force the index hint to be used in my query?

Answer:Oracle index hint Syntax is tricky because of the index hint Syntax is incorrect it is treated as a comment and not implemented. Here is an example of the correct Syntax for an index hint: select /*+ index(customer cust_primary_key_idx) */ * from customer; Also note that of you alias the table,you must use the alias in the index hint: select /*+ index(c cust_primary_key_idx) */ * from customer c; Also,be vary of issuing hints that conflict with an index hint. In this index hint example,the full hint is not consistent with an index hint: select /*+ full(c) index(c cust_primary_key_idx) */ * from customer c;
