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.

    2 Questions

    1. Can alpha handle files in the 8 gig range?
    Tried it - system gagged on the read.

    2. Bigger problem

    I'm trying to join two files. The master and transaction criteria work fine and are dumped into a result file.

    HOWEVER, I need the non matching records in the result file as well and the join is omitting them.

    How do I go about doing this?

    You must want something other than a join. By definition a join contains all the records from the master file and matches from the transaction. Asking it to include non-matches is contradictory.

    I am guessing you probably want to create a new table, probably just a copy of the master, and append all records from the transaction table.

      Bob, in answer to question 1, Alpha Five dbf format is limited to 2 billion records. Check the Index entry for "Specifications for Alpha Five" in the help file.

          Copying

          Stan

          If I copy the source file into a new file and then append, will this work even though the two files will now have different field counts?

          If source has 31 fields and the joined file has 53 will the 31 field be modified to match the 53 or am I going to throw a consistancy error?

            I really don't know what you are trying to do. I was guessing. A join made no sense to me when you said you wanted non-matches.

            What is your desired end result?

              I handle court records. Example

              field names
              1. name
              2. date of birth
              3. penal code #
              4. charge
              5. court
              6. disposition.

              Some of the data I receive is fragmented into tables and needs to be joined into a single flat file (comma delimited format)

              penal code is in one file and the charge in a different file - they need to be joined or intersected.

              However, not all the records will have the penal code # in them. Regardless, I have to keep that record with the joined records. Otherwise i have gaps in the database.

              After joining 2 files - I am short 150,000 records in the result file. This isn't tolerable.

              I tried to append the two files - but they have different fielding after the join. - So that isn't going to work

                You've lost me. Let's hope someone else jumps into the discussion. (I would have said "joined in" but I hate puns.)

                  Bob,

                  I think what is confusing the matter is the fact that a join or intersect is usually on 2 files that have the same record types. ie) the fields are the same in each.

                  Let me guess, but are you trying to say that there is one part of information in one file and you want to have fields in the other APPENDED to the SAME record?

                  eg) File 1
                  Name
                  Date of Birth
                  Penal Code #

                  File 2
                  Name
                  Charge
                  Court
                  Disposition

                  What you want:
                  Name
                  Date of Birth
                  Penal Code #
                  Charge
                  Court
                  Disposition

                  That's what I am seeing in your example above.

                  If not maybe you can elaborate a little more on your structure so that we can tune in to your problem.

                    Essentially you are correct.

                    These files are table'd that is, broken into portions that have a common field which can be used to link the two pieces together into one new record.

                      Then you probably just want to link them as a set and then create an operation to output all records to a new file of your specification.
