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!

Update a date field to NULL

Asked by grunners80 in Access Coding/Macros, Microsoft Access Database, SQL Query Syntax

Hi
I'm not sure if I'm going about this the right way.  I'm trying to update a table with values from a form.  The problem I am having is that sometimes these values are empty, and sometimes they have data.  I've got round this by using IIF functions in my update statement, however this isn't quite working on a date field.  Basically the date may be blank, in which case it should update the datetime field in the table to null, or it may have a date value (running the update in this instance works).  I'm getting type conversion errors when I try to update to null.  Code attached, many thanksStart Free Trial

         "dbo_tbl_Weekly_Expenses_Temp.[LaundryLetters1Date] = IIf(IsNull('" & LaundryLetters1Date & "'),'', '" & LaundryLetters1Date & "') " & _ 'This line errors, updating datetime field
