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!

MYSQL query syntax, subquery joins alias

Asked by techport13 in SQL Query Syntax

The following query returns an error saying that I have invalid syntax near ' ' at line 1.  The basics of this is:

I have a stock_history table that stores historical stock prices, a stock company table that stores the company name and symbol, and a stock transaction table that stores each buy/sell transaction.

I'm writing the query to display someones portfolio - so it will show the company names, the number of shares the person owns and the most recent price of each company's shares, ie: google - 200 - $12.54

If i remove the subquery in the where clause, the query executes just fine.

I will also have to eventually modify this query so that it will only use use qty rows from the stock_transaction table when the date of the transaction is greater than the date the company was activated.Start Free Trial
