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.

    Join Table-Filter Child Table Complex

    I am trying to Join a parent and child table to create One table in order to export to Excel. I realize it will only pick the first child to match - My issue is that I want a specific record and if that doesn't exist then the first record.

    The parent table is A Land database, and the child is all the owners - which could be one or several. They are linked by rec_no, The owners may have a lease associated with them. I have a field in the Owner table called Lease_rec_no - If I do a filter and only pick those childs with Lease_rec_no>0, then if there is no lease, I don't get any of the Child info, although I still get the parent(which I want). What I want to do is pick either the first Owner with a Lease_rec_no>0 or if none of the owners have a lease_rec_no, pick one of owners(doesn't matter to me which one - just need one- could be first or last) After this join is done, I have a set that this table is then matched to (the lease info)Prior to my export so that I only end up with one record, some of which have lease info and some that dont, but all my land and at least one owner record is there. Unless someone can think of a better way to get all this info in my export.

    Example: Table Fields Link
    Property Rec_No Rec_No to one-many Owner
    property Id
    Owner Rec_No Rec_No to Property
    Owner_rec
    Lease_Rec_No Lease_Rec_no to Lease_Info
    Names
    Perc Owned
    Lease_Info Lease_Rec_No Lease_Rec_no to one-Many Owner
    Lease_No
    Lease_Status

    So there is ALWAYS only One Property Record, and One Lease_Info Record, but there could be Many Owners per piece of Property, or Many Owners per Lease(that could possible be different pieces of Property)

    i.e.
    Property Rec_No 1 Property ID 123
    Rec_no 2 Property Id 456
    Owner Rec_No 1 Owner_rec 1 Lease_rec_no Null()
    Rec_no 1 Owner_rec 2 Lease_rec_no 1
    Rec_no 1 Owner_rec 3 Lease_rec_no 2
    Rec_No 2 Owner_rec 4 Lease_rec_no Null()

    Currently my join would give me (As I did filter for Lease_rec_no >0)
    New Table Rec_No 1 Property_ID 123 Owner_rec 2
    Rec_No 2 Property_Id 456 No owner Rec

    I need the info on Rec_No 2 from Owner Rec even though there is no Lease_rec_no.


    This is run on the entire table, not just one Parent record.

    I have looked at first(),last(),tablemax() and none of those seem to work.

    Any suggestions??

    Hi Leah,

    I haven't read your request really close but how about this idea?

    Make a copy of the child table. Then, remove the records that do not meet your criteria. To do that, you could create a query, mark the records and then delete the marked records. This method should simplify the join process.

    Knowing what you can achieve will not become reality until you imagine and explore.

      Hi Leah,
      I worked up an example that covers what I believe you described you needed. There are direction on the menu form that opens when db is opened. I hope this helps, and if you have any questions, please holler back.

        Your sample looks exactly like what I need. I will play with it with my real data and see if I can get it to work.

        Thanks so much
