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.

  • Turning off Auto Increment during append

    I have 2 tables test1 and test2
    Test has a field rule for autoincrement
    When I use a batch append form Test2 to Test1, I do not want the autoincrement field to work.
    I tried using the tbl.enter_begin(.F.). But it still "honors" the filed rules.
    I could manually delete tha rules then add it back, but that's a pain.
    I read many of the posts here as to which rules are honored etc. But none answer my question.
    Any help would be appreciated.

    Re: Turning off Auto Increment during append

    For a table named test with an autoincrement field named id I did this in the interactive editor.

    Code:
    tbl = table.open("test")
    rul = tbl.rules_get()
    
    ? rul.id.data_type
    = "AutoInc"
    ? rul.id.Default.Default
    = "00001"
    ? rul.id.Default.Type
    = "Simple"
    
    tbl.close()
    Which means you could

    Code:
    tbl = table.open("test")
    rul = tbl.rules_get()
    rul.change_begin()
    rul.id.data_type = "User"
    rul.id.Default.Default = ""
    rul.id.Default.Type = "None"
    rul.change_end(.t.)
    tbl.close()
    before the operation and


    Code:
    tbl = table.open("test")
    rul = tbl.rules_get()
    rul.change_begin()
    rul.id.data_type = "AutoInc"
    rul.id.Default.Default = "00001"
    rul.id.Default.Type = "Simple"
    rul.change_end(.t.)
    tbl.close()
    after it.
    There can be only one.

      Re: Turning off Auto Increment during append

      If I understand this.
      This will allow me to append to Test1 with autoincrement turned off.
      Which means that the filed value in test2 would be appended with the original values intact?
      Correct?
      Thanks

        Hi Stan,
        Why change the default type and value at all? Wouldn't it be enough to just change the rul.id.data_type from Auto_Inc to User then back again?

          The indicated code removes the autoincrement field rule and then puts it back in place so you should be able to do what you want.

            I'm not sure what would happen if two parts of the auto increment process are left in place and one is removed. I don't use auto increment so I don't have the experience to rely on.

              When field rules are changed from Auto Incr to User the default doesn't change since it can be used for either setting. So it seemed like it wouldn't necessitate changing it to turn it off and on for an append operation.

                  Easy enough to check out but know you are correct as I have had to do this manually before and all that was necessary was to turn the AutoInc to User and then back again. This is how I figure out how to do a lot of my scripting....do it manually and then mimic this with xBasic. With this approach it so far has made anything I have wanted to do very easy to implement in xbasic / Action Script. Just have to find the right functions to do it with (sounds sooooo easy doesn't it! :) ).

                    Hi Jeff,

                    Looks good on the surface...but I do not think there is a need to close the table "test" until the very end...IOW open the table, leave it open until the end of the script and then close it. Instead of opening it twice and closing it twice.

                        Re: Turning off Auto Increment during append

                        It's amazing what I can learn form this board. I now understand it. And it works.
                        The only thing that doesn't happen is the field rules going back to "AutoInc"
                        The beginning of the script removes the field rule, then appends without the rules. However, it is not putting back the rules. Any suggestions?
                        Thanks again for the help.

                          Hey Stan,
                          You may not need to close the table after the first change_end() but if you open the table again it will be pointing to an alias - which is perhaps why Jeff couldn't get the field rule to change back? Because another instance of the table was left open.

                            rul = tbl.rules_get()
                            rul.change_begin()
                            rul.sysid.data_type = "AutoInc"
                            rul.sysid.Default.Default = "00001" '<-change this to whatever your real default might be
                            rul.sysid.Default.Type = "Simple"
                            rul.change_end(.t.)
                            tbl.close()
                            There can be only one.

                              Thanks for the help.
                              It still does not put back the rules.
                              Any solutions?
                              Thanks.
