The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

select using substituation variable

Asked by leoahmad in Oracle Database

Tags: , ,

I want to write a query that returns result using a substituation variable
Suppose in the well known emp table i want the result of those employees who are hired in December not concerning with their day or year.
I write the query

select ename, hiredate,sal from emp
where hiredate like '%&date%'

on sql prompt if I write "DEC"  for substituation variable then it gives accurate result

ENAME      HIREDATE         SAL
---------- --------- ----------
SMITH      17-DEC-80        800
JAMES      03-DEC-81        950
FORD       03-DEC-81       3000

but i want to spelled out month as "DECEMBER" in substituation variable then it gives wrong result. For similar results I write the query

select ename, hiredate,sal from emp
where hiredate like TO_DATE('%&date%','%MONTH%');

The results are:

Enter value for date: DECEMBER
old   2: where hiredate like TO_DATE('%&date%','%MONTH%')
new   2: where hiredate like TO_DATE('%DECEMBER%','%MONTH%')

no rows selected
