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.

UPDATE DATA IN ONE TABLE FROM ANOTHER USING A SELECT STATEMENT

Asked by ewgf2002 in PL / SQL, Databases Miscellaneous

I am trying to use the following code to update data from one table and put that data from the select statement into another table. The code is as follows:

update invcost a
set a.glaccount = (select b.GLACCOUNT from nventory b
where a.ITEMNUM = b.ITEMNUM
and b.GLACCOUNT is not null)
where exists
(select 1 from inventory b
where a.ITEMNUM = b.ITEMNUM
and b.GLACCOUNT is not null )
and a.glaccount is null

THE ISSUE IS I AM GETTING ORA-01427: single-row subquery returns more than one row.

I am assuming this is because the values in the table from the select has more than one value. For example: The glaccount field in inventory is either, 1234, 5678, 9101, 3214.

I need to update the fields in invcost to the same values in inventory.
