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.

  • Calculated Field in Browse Table Showing Field Counts

    I am using A5 V10.5. I know that is old, but I have a good reason for using it. However, I have not done any real serious DB creating for a while and am out of practice.
    I have created a browse table for a table I created and am trying to create a calculated field showing the number of duplicates in a field in that table.
    The table looks like this:

    Part Number Serial Number PO Number
    5A/250VP 123456 207544
    5A/250VP 654321 207544
    CON-6310 456789 207669
    CON-6310 987654 207669
    CON-6310 123654 207669

    It is a very small table of part numbers with associated serial numbers. Each part/serial number combo is unique. When part/serial number is used (referenced from another table) that unique combo is pulled from this table then posted to a history table and deleted from this table. As you can see from the example above, part numbers can be listed several times. I know this table structure does not follow First Normal Form, but there is a reason for that. There are actually only 14 part numbers currently in the database, but each part number has several serial numbers, so each is listed as a separate record. There are currently 81 records in the table. It is not likely the number of part numbers will increase, but the number of part/serial number combos could increase as new parts are purchased and added to the inventory.
    What I want to do, as mentioned previously, is create a calculated field in the custom browse table to count the number of each duplicate field value in the table. That should give me a total quantity of each part.
    I have searched through the forum and cannot find anything that will help me with this. I know this should be pretty easy but, as I said, I am way out of practice and am just spinning my wheels. Can anyone get me going in the right direction?

    For a small table,

    dup = tablecount("your_table_name","field_name_to_count = "+s_quote(field_name_to_count))
    There can be only one.

      Thanks Stan. Hmmm. When I enter the expression you gave me in the browse table's calculated field Expression Builder, tablecount("sfpart_serial_inv","partnum = "+s_quote(partnum)), it equates to a valid expression with a result of "4." That could be that the first four records in the table have the same part number (partnum) of "5A/250VP." If I use the > key to tab through the rest of the records, the result remains at "4." Is there a way I can count the records based on the field value of partnum?

        The expression does that. I don't know what you are seeing in the expression builder but it should work correctly in the browse.

        tablecount("sfpart_serial_inv","partnum = "+s_quote(partnum))

        reads as

        count the partnum field in the sfpart_serial_inv table where the value in the partnum field is equal to the current value of the partnum field. Thus it changes for each partnum.

          Thank you so much Stan. It does indeed work. I could not understand, at first, why I could only see the count for parts that were less than ten. Then in the Column Properties>Format Tab I found the Display Format width was set to 1. Du-u-uh! LOL
          Thanks again.
