Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • lookup() or conditional lookup

    I need to do lookups from two different tables. In the first table is the member id which will serve as the lookup link to be used in the second lookup table. Five numeric values has to be lookuped up in the second lookup table with member id in the first lookup table as the filter. Can't get it right. Please help!

    A few details like

    fieldnames and types
    what criteria to use for the member id lookup

    would go a long way to getting help.

    If you want to return five values from one table you should probably use table.external_record_content_get() instead of lookup().
    There can be only one.

      Table 1:Member_Number Character 50 0
      Payment_Date Time 17 0
      Total_Contribution Numeric 19 2
      Invest_Amount Numeric 19 2
      Unit_Rate Numeric 19 2
      Unit Numeric 19 2
      Admin Numeric 19 2
      Consulting Numeric 19 2
      Reserve Numeric 19 2
      Risk Numeric 19 2
      Option_Id Numeric 19

      Lookup table one:Member_Id Numeric 11
      Member_Number Character 50
      Surname Character 50
      Name Character 50
      Option_Id Numeric 19

      Second lookup table:Option_Id Numeric 11 2
      Option Character 50
      Employee_Contribution Numeric 19 2
      Employer_Contribution Numeric 19 2
      Total_Contribution Numeric 19 2
      Employer Invest Contribution Numeric 19 2
      Total Investment Numeric 19 2
      Risk Numeric 19 2
      Admin Numeric 19 2
      Consulting Numeric 19 2
      Reserve Numeric 19 2

      The fields to be filled from the first lookup table is member_number & option_id. The product_id then will be the filter for the lookups in second lookup table to write in the different amounts e.g. employee_contribution, employer_contribution etc. This values can change from time to time in this lookup table.
      Hope you have an idea now

        I was getting along pretty well, even without the table names until I came to

        The product_id then will be the filter for the lookups in second lookup table to write in the different amounts e.g. employee_contribution, employer_contribution etc.
        There is no product_id field in any of the three tables?

        Is there any way you can attach a sample database with instructions like

        I want to use the aaa form
        While viewing a member I want to lookup his/her member_id based on the member_number and option_id
        I want to use that member_id (product_id?) to .....
        There can be only one.
