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.

    Re: Excel Sql connection

    Ted,
    The answer to 1) is yes. 2) Yes for "c" data, for Numbers data type is made to "E" 20,0.

    In may app ,the user downloads an excel table from "overstock.com" which is the inventory listed on the site.
    My app imports the excel inventory ,updates it and then make an CSV file to upload to the site.
    Every thing works fine but "overstock.com" changes the field names and position from time to time.
    So to cope with this the user has to change the format and the top row of the downloaded excel table before my app can import the table.
    I like to give the user a way to be able to choose the correct column of the excel table to import to the correct corresponding field.
    I know this probably can be down by coding a append operation ,but it would so much easier with the Sql connection ,If worked.
    How would you do this?
    Thanks,
    Nick

          Re: Excel Sql connection

          Ok, had a think about this now.
          Couple of issues,
          Data Formatting. The Numerics are in Scientific Format in Excel? Cannot see how this would be required unless you are building something to very tight tolerances.
          The Import routines. I had presumed that you had looked at the text in the Import Panel explaining what to use. Obviously an incorrect assumption on may part - sorry.
          In the scenario you describe I don't think that you will be able to do much for the user automatically - even if you parse the field content and try to select the fields based on the actual content.
          It depends on the number of fields in the Excel table. If there are only 3 for example - like those in post #1 it could be easy.
          You mention that the field names change but the data remains the same? If so, then Field 1/2/3 no matter what their title will contain the data you anticipate.
          However you say later that the field positions sometimes change, and that is the killer.

          If there are 100 fields and all need analysing, it's a chore.
          I wouldn't use SQL, I'd create a template Excel sheet(1) which is in the correct format, and insert the data sheet (2) which is downloaded, then copy the data from (2) to the relevant column in (1).

          At some point, one side of the process has to be consistent and if you have no control over the incoming data, it needs to be on your side.
          If you go the SQL ADO route, then depending on the number of fields to be imported and computer savvy users, it may work but requires a great attention to detail.

          Have you looked here?

            Re: Excel Sql connection

            Thanks Ted , I am going to use the "a5_AlphaDAO_Import" operation ( the xbasic code) .I can get a list of the excel column names via excel sql connection then I use the list as choices for combobaxs controls in a xdialog window .Each of this controls (variables) corresponds to a field-name in my dbf table .After the user selects the corresponding fields then it's easy to code the query and the field mapping parameters required by "a5_AlphaDAO_Import.
            Thank you, Ted and Stan for your help.
