Oracle SQL Tuning Tips - 3

• Oracle automatically performs simple column type conversions(or casting) when it compares columns of different types. Depending on the type of conversion, indexes may not be used. Make sure you declare your program variables as the same type as your Oracle columns, if the type is supported in the programming language you are using.Use:
  SELECT emp_no, emp_name, sal FROM emp WHERE emp_no = ’123′;
  HERE if emp_no indexed numeric, then after implicit conversion query will be:
  SELECT emp_no, emp_name, sal FROM emp WHERE emp_no = TO_NUMBER(’123′);
  Thus, index is used in this case.
  Don’t use:
  SELECT emp_no, emp_name, sal FROM emp WHERE emp_type = 123;
  HERE if emp_type is indexed varchar2, then after implicit conversion query will be:
  SELECT emp_no, emp_name, sal FROM emp WHERE TO_NUMBER(emp_type) = 123;
  Thus, index will not be used in this case.
