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.

  • ADO vs Alpha DAO

    I am stumped -

    I have been sucesfull building a web app using ADO that displays SQL data from a Pervasive database. To date I have not been able to update the table. I receive an error message that the table was not updated.

    I have been unsuccesful using Alpha DAO. I connect to the same sql server. When I attempt to run a live preview I receive the following error mesage displayed across the top of the header

    [Pervasive][ODBC Client Interface][LNA][Pervasive][ODBC Engine Interface]Invalid column name: 'BKCM_ACCT_REM 1'. SQL State is: 42S22 [Pervasive][ODBC Client Interface][LNA][Pervasive][ODBC Engine Interface]Error in expression: BKCM_ACCT_REM 1 SQL State is: HY000

    I use the same DSN for each.

    1. Should I just use ADO and try to correct the update issue?
    2. What recommendations are there for getting Alpha DAO to run?

    Thanks in advance

    I doubt you will be successful with either ADO. The problem is the space in the column name. Generic SQL does not like that.

    BKCM_ACCT_REM 1

      Thanks for the reply - That is interesting, I have been using this same driver and DSN with Paradox, (BDE) for years and not had a problem.

      Is it the "space" creating the update error when I hit submit from the ADO form?

      Thanks again

        Re: ADO vs Alpha DAO

        Funny you should ask, as I thought that is what I said. I will be more specific.
        You cannot use a space in an Identifier/Column Name. So YES, the space is the problem. It does not follow the SQL standard.

        Here are a couple of reference pages:

        http://www.dbcenter.cise.ufl.edu/tri...fm.html#144132

        http://www.postgresql.org/docs/8.0/s...AX-IDENTIFIERS
        (click on Identifiers and keywords in above)

        The problem with Paradox is that it allows deviation from the SQL standard with regard to identifiers.

        You might, however, try a quoted column name:
        EG:
        Instead of
        SELECT BKCM_ACCT_REM 1 FROM some_table;

        try
        SELECT "BKCM_ACCT_REM 1" FROM some_table;


        No guarantee it will work though.

          I had another thought regards your problem.

          Is the column name really "BKCM_ACCT_REM 1"

          Or did you really mean to do
          SELECT BKCM_ACCT_REM, 1 FROM some_table;

          IOW, did you leave out the comma separator?

            I need to caution that I am not a programer - Only a hack. I developed the grid using the wsiwyg editor. I had a look at the actual DB using a pervasive editor. The field is: BKCM.ACCT.REM

            The field constructed by the editor is:
            tmpl.ADO.SQL = "SELECT BKCM_ACCT_CODE, BKCM_ACCT_OLDCD, BKCM_ACCT_ALPHA, BKCM_ACCT_NAME, BKCM_ACCT_ADD1, BKCM_ACCT_ADD2, BKCM_ACCT_ADD3, BKCM_ACCT_CITY, BKCM_ACCT_STATE, BKCM_ACCT_ZIP, BKCM_ACCT_CNTRY, BKCM_ACCT_CONT1, BKCM_ACCT_TITLE, BKCM_ACCT_PHONE, BKCM_ACCT_FAX, BKCM_ACCT_REP, BKCM_ACCT_DLOAD, BKCM_ACCT_SICCD, BKCM_ACCT_CUST, BKCM_ACCT_LEAD, BKCM_ACCT_START, BKCM_ACCT_TERR, \"BKCM_ACCT_REM[ 1]\", \"BKCM_ACCT_REM[ 2]\", \"BKCM_ACCT_FONE[ 1]\", \"BKCM_ACCT_FONE[ 2]\", \"BKCM_ACCT_FONE[ 3]\", \"BKCM_ACCT_FTWO[ 1]\", \"BKCM_ACCT_FTWO[ 2]\", \"BKCM_ACCT_FTWO[ 3]\", \"BKCM_ACCT_FTHRE[ 1]\", \"BKCM_ACCT_FTHRE[ 2]\", BKCM_ACCT_FTIME, BKCM_ACCT_CCARD, BKCM_ACCT_CNUM, BKCM_ACCT_CEXP, BKCM_ACCT_CMPNM, BKCM_ACCT_PNAME, BKCM_ACCT_EXTRA, BKCM_ACCT_EMAIL, BKCM_ACCT_EMPS FROM BKCMACCT_B ORDER BY BKCM_ACCT_CODE"

            I assume these fields BKCM.ACCT.REM and BKCM.ACCT.FONE etc are arrays.

            Can I manually edit the SQL statement to remove these fields?
            If yes how do I enter the editor?

            Thank you very much

                Yes, they are arrays and I don't believe the ADO handles them very well.
                I would not play with the query. Just recreate the grid and do not include those fields.

                  Thanks again - I will need a bit more help. How do I filter out the fields?. They are already set to not display.

                    I think I have it. I was building the grid based upon a table. I will rebuild using an sql querry and only include the fields I require.

                    Thanks again - your help is much appreciated.
