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!

Editing IBQuery in Delphi 5

Asked by sburck in Delphi Programming

Tags: ibquery

We have an IB database with a table, which we'll call table TableA.  There is also a TableB that is linked to TableA by a foreign key.  We have two IBQuery components with two IBUpdateQuery components for editing and updating.  There are also two IBTransaction components, one for each of the tables.

When we try to delete from TableB, and then delete from TableA, we get an IB error which claims "Deadlock violation on Foreign Key".

Now, this is probably true deadlock.  However, the docs tell us that when using Midas (which for now we are trying), each IBQuery should have its own IBtransaction component.

What can we do to get around this?
