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!

Deleting Multiple Rows Using CFquery

Asked by verge02 in ColdFusion Application Server

Tags: using

I need to delete multiple rows of datas that has the same attribute...

<!--- Check if data exists with conditions ---->
<cfquery name="checkPurchase" datasource="masterhub" dbtype="odbc">
     SELECT *
     FROM wsPurchase
     WHERE PURCHASE_MAS_NO='#form.MAS_NO#'
</cfquery>

<!--- If there are at least one row of data, perform delete --->
<cfif checkPurchase.recordcount gt 0>
<cfquery name="deletePurchaseInfo" datasource="masterhub" dbtype="odbc">
     DELETE FROM wsPurchaseInfo
     WHERE wsPurchase.PURCHASE_MAS_NO='#form.MAS_NO#'
     AND wsPurchase.PURCHASE_ID=wsPurchaseInfo.PURINFO_PURCHASE_ID
</cfquery>

The coding I use is pasted above which obviously is not correct... but the idea is there.

I want to delete rows from table wsPurchaseInfo in which are the column wsPurchaseInfo.PURINFO_PURCHASE_ID (FK) is related to column wsPurchase.PURCHASE_ID (PK). The condition is that if the value in wsPurchase.PURCHASE_MAS_NO is the same as #form.MAS_NO#, then perform delete for rows in wsPurchaseInfo that is related to that data.

Ermm... confusing? I hope you understand what I want to achieve! :)

Thanks.
