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.

    Report Based on a Set

    I have a simple set based on three tables. The two child tables appear on a report as sub-reports.

    The report prints fine as long as there are records in either of those child tables which are linked to the parent record
    using a single linking key field, but if both of the child tables (sub-reports) are blank, the overall report won't print.

    The response is "Report does not contain any records."

    I can't recall ever having this problem before with sub-reports so I'm sure I have something set wrong, but so far
    I haven't been able to see anything that looks unusual.

      Make sure you're doing a left outer join when joining the two child tables.

        Re: Report Based on a Set

        Hi Al,
        The majority of the data in the report all comes from the parent table, and when the user clicks on an action button on a web grid, it filters the report to the linking key of that particular record in that parent table. The two child tables also use that same linking key to display additional data.

        Hi Josh,
        I don't think I understand what "left outer join" means for linking to child tables. Can you elaborate?

          When you join the child tables to the parent you specify the type of join. By default it's an inner join. Try changing it to left outer join.

                    Okay. Al here are the files. You'll see that the first sample entry, which has data in both child tables prints correctly, but the second sample entry (which has no child data) says "No records found" when trying to print.

                    Thanks for taking a look at this.

                      You have a good one.

                      It's acting unexpectedly for me.

                      Still looking for a way to make it work with out extra records in the child tables.

                        Well I'm glad to know I'm not the only one!

                        Thanks Al. The weird thing is that I have many other sets such as this one with printed reports using sub-reports for the child tables, and have never run into a problem when the child table had no linked records.

                        I appreciate any assistance you can give me, as I have no hair left on my head to pull out. (LOL)

                          Rich

                          A couple of things to do to make this work.

                          Looks like the problem is where the filter for the child tables is placed.

                          Instead of putting them in the subreport properties, they work if put into the set filter.

                          Then the subreport properties can default to filter on the appropriate table.

                          Also in the report, since you are using subreports, you need to group on the linkingkey (or some unique number in the table) and use a header at that group.

                          Attached is a new set that you can add to your database and have a working report.

                          Be aware of an issue with the filter of the report keeping the filter passed to it when you modify the report.

                          Your report had a filter of linkingkey = "000000" which didn't help, but wasn't the primary problem.

                          Unzip this file and place the files in the workspace directory. Then add the set to the workspace.

                          caset1tomany.zip

                          and now my hair is gone too.

                            Thank you ever so much Al.

                            I followed your advice and copied your set and now it works perfectly!

                            And oh yeah, sorry about the hard-coded filter of "Linkingkey = "000000." I had put that in there so I could test the report right from the design mode without having to go back and open it from the web grid, and I forgot to remove it before zipping up the file to send to you.

                            I'm sure there was some cussing of my name when you found that during your troubleshooting. LOL

                              NO cussing. It looked like something I'd do, so I found it early in the process.

                              Hope that works for you.

                              It's OK if the set only contains the report.

                              There have been a few times that I have a single purpose set.

                              And now I try to do most everything in a set, even if it's a single table set.
