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.

  • Running an append using an array

    Hi

    I am struggling to get this to work!

    I have three tables.

    Table A (Owners) contains details of individuals entered into a competition. The [ownerkey] field is the unique id field.

    Table B (fixtures) contains details of games taking place. The [gamekey] field is the unique id field.

    Table C (predict) is the recipient table for the new records. The structure is the same as fixtures except for three extra fields (Ownerkey, fname, lname) all of which are present in the owners table.

    For each owner in the owners table I need to append 1 copy of each record in the fixtures table so say there are 20 owners and 30 fixtures there would be 600 records in the predict table. If another 2 owners are added then an additional 60 records would need to be appended.

    So I figure that I should create an array for the owners table records (which works in the interactive window) and then work through each entry using a for each loop.

    The script below attempts to do this but falls over when it reaches the first field needed from the array. (see attached image)

    DIM Append as P
    DIM UserFname as C
    DIM UserLname as C
    DIM UserKey as C
    dim AppUserkey as C
    dim tbl as p
    dim arr_count as N

    tbl = table.open("owners")
    arr_count = tbl.records_get()
    tbl.close()

    dim raw[arr_count] as P
    dim ownerkey as P
    raw.initialize_from_table("owners")
    dim i as N
    for i = 1 to arr_count
    userkey = raw[i].ownerkey
    AppUserkey = ""
    AppUserkey = "str(GM_KEY_F,3,0)-"
    AppUSerkey = AppUserkey+userkey
    UserFname = raw[i].fname
    UserLname = raw[i].lname

    a_tbl = table.open("predict")
    append.t_db = "fixtures"
    ON ERROR GOTO ERROR24052010161937986

    append.m_key = "str(GAMEKEY,3,0)-OWNERKEY"
    append.t_key = AppUserkey
    append.m_filter = ""
    append.t_filter = "Cmp_Rd_F=1"
    append.type = "Unique only"
    append.m_count = 7
    append.m_field1 = "Gamekey"
    append.m_exp1 = "@Fixtures->Gm_Key_F"
    append.m_field2 = "Comprnd"
    append.m_exp2 = "@Fixtures->Cmp_Rd_F"
    append.m_field3 = "Hmtmkey"
    append.m_exp3 = "@Fixtures->Hm_Tm_F"
    append.m_field4 = "Awtmkey"
    append.m_exp4 = "@Fixtures->Aw_Tm_F"
    append.m_field5 = "OWNERKEY"
    append.m_exp5 = UserKey
    append.m_field6 = "FNAME"
    append.m_exp6 = UserLname
    append.m_field7 = "LNAME"
    append.m_exp7 = UserLname
    append.t_count = 0

    a_tbl.append()
    NEXT


    GOTO CONTINUE24052010161937986
    ERROR24052010161937986:
    ON ERROR GOTO 0
    ui_msg_box("Error","Error running Append Operation"+crlf()+error_text_get())
    END
    CONTINUE24052010161937986:
    a_tbl.close()
    'If the Operation is run from within a Form or Browse, then refresh the window
    if is_object(topparent.this) then
    if topparent.Class() = "form" .or. topparent.class() = "browse" then
    topparent.Refresh_layout()
    end if
    end if
    Any thoughts gratefully received.

    Kind regards

    Re: Running an append using an array

    A key expression is a field or combination of fields that Alpha Five uses to determine which table records are considered unique.
    I don't see how you can make an array value fit that requirement.

    You should be able to do this with an xbasic loop instead of the append operation.
    There can be only one.

      I agree. A pair of nested loops. Loop through the owners, and for each owner loop through the fixtures.

        Thanks, guess I was trying to make things too difficult for myself again!
