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.

  • Linked Content to Grid using SQL Join

    Has anyone experienced errors when linking to a grid that uses a SQL join?

    I successfully used the Linked Grids/Content property when the linking grids have a Query(AlphaDAO) based on "Table or View". But I am having problems using the Linked Grids/Content property to link grids that Query(AlphaDAO) based on "SQL Select Statement". The linked child information is not showing when I bring up the parent row. Also when I insert a new record on the child grid I get the error: Could not refresh Detail View after inserting record. No records were found when executing the 'Refresh row' query.

    The child row does get inserted into the sql table but the grids are not finding it.

    Re: Linked Content to Grid using SQL Join

    I can say that I do have linked content using MySQL joins and am not having an issue with inserts or updates. An example of the SQL SELECT statement is:
    SELECT px_info.PK_Int AS PK_Patient_info,  dayname(DATE_OF_APT)  AS Day_of_Week, appointments.fk_px_info, appointments.DATE_OF_APT, appointments.TIME_OF_APT,
     appointments.TYPE_OF_APT,  Concat_ws(' ', px_info.LAST_NAME, px_info.FIRST_NAME, px_info.MIDDLE_INI)  AS Name, appointments.NEW_PATIENT, appointments.REFERRED,
     ( DATE_FORMAT( FROM_DAYS(( TO_DAYS( NOW() )  -  TO_DAYS(px_info.DT_OF_BIRTH) )) , '%Y')  + 0) AS age, appointments.PK_INT AS PK_Appointments, appointments.CREATE_DTF, appointments.CHANGE_DTF 
    FROM appointments appointments
    	 INNER JOIN px_info px_info
    		 ON  px_info.PK_INT = appointments.FK_Px_Info    
    ORDER BY appointments.DATE_OF_APT DESC, appointments.TIME_OF_APT
    As you can see I'm also doing an age calculation and concatenating some fields as well. No problems at all on this linked grid.
