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!

Joining two tables in 10G

Asked by jim_1234567890 in Oracle Database

Tags: , ,

I have to two tables:

SELECT A.id, A.desc FROM TABLE_A A

YIELDS:

TABLE_A
----------
ID     DESC
---    --------------
1      THE_ONE
2      THE_TWO
3      THE_ THREE



SELECT B.ID, B.quantity, B.BATCHID
FROM  TABLE_B B


TABLE_B
----------
ID     quantity  BATCHID
----   --------  -------
1       -17      499
2       -87      499
2       87       500
1       17       500
2       82       501


In older version I could go a query like this:

SELECT ta.id, ta.desc, nvl(tb.quantity, 0) quantity
   FROM TABLE_A ta, TABLE_B tb
  WHERE ta.id = tb.id (+)
    AND TB.BATCHID = 499

would result in this:
ID     DESC            quantity
---    --------------  ------
1    THE_ONE            -17
2    THE_TWO            -87
3    THE_THREE          0


But now in 10G when issue the same query it does not appear to do the outer join correctly.
I get:
ID     DESC            quantity
---    --------------  ------
1    THE_ONE            -17
2    THE_TWO            -87

I wanted all quantities in Table_b as they relate Table_a (for all IDs).  What happened to the id = 3?  I now table_b does not have any id = 3 fro the batch but as it is outer joined table_a it should give a result even if it is null.

How does the outer join in 10g differ?
How do you correct old code so the joins work correctly under 10g?
How wouldyou correct this code to work in 10g?
