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.

    Inserting data

    Hi there, I having trying many ways to insert new data into my customer table. The customerid was the key and it uses the First character of the Last name follow by running number. How do I append new customer to the next record. Below is the before and after results. Please highlight me how to do it.

    Thanks

    Re: Inserting data

    It's extremely helpful to see the code you are using.
    It would also be helpful to know if you are using dbfs or sql, and if sql, which "flavor".

      Re: Inserting data

      You can add a Quick Sort to the onsave event of the browse to resort the data in order of the Customer ID.

      Use Action Scripting to help generate the code needed.

      So the data will appear in the order you requested after a save of the data.

      The underlying data in the table is still in chronological order, but is displayed in Customer ID order.

      Not sure how you are generating the Customer ID, so the timing can be an issue.

      (and what Gregg asked for is helpful too..)

        Al,
        From the looks of the images supplied, each letter of the alphabet has it's own running total (ie: there are potentially 26 customer ids ending with 0001).
        This requires more than just a simple sort (at least in my opinion).

        Leong : On a practical side, I won't tell you this is wrong, but I will ask you what happens when a female client changes her last name
        due to marriage or divorce ?

          No given the data shown, a simple sort works. It does have a limit of 99,999 per prefix letter.
          Remember Y2K? Back in the 1960's no one thought by 2000 we'd still be using the data collected earlier. YEAH!

          What is interesting to me is how the ID is generated. Haven't heard back.
          I know how to do it.
          Have a control table that has entries for all prefixes need and a counter field to increment.
          Just curious how this one works.

          Yes the always changing names usually suggests an actual ID field that doesn't change and a reference field that does change as data changes. (ie the ID field shown)

            For my thinking, this is far easier to do with sql than dbfs, even though it is very doable with either.

              I have no idea how to start, the table is link to MSSQL database. The biggest issue was how to get the last record of that particular character of the Last Name.

                Hi Gregg, the Customer ID will not change even a female client changes her last name.

                  Re: Inserting data

                  This code will easily get the highest customerID.
                  More help can be provided if we see what you have going.

                  Code:
                  select max(customerID) from customerTable
                  where left(customerID,1)=left(lastName,1)

                    Hi Al, I have thought of using a control table with all the 26 Alphabets and the last running number. This was from an old VB6 program. Upon saving the data, the program will look at the existing table and generate the new customer ID.

                      Leong,

                      I am stabbing at the solution here because I have no real sample data to work with.
                      The code below "should" work, but obviously needs to be tested with actual tables and columns.
                      Code:
                      set customerID = concat(left(m.lastName,1),right((select max(q.customerID) from customerTable q where left(q.lastName,1)=left(m.lastName,1)),4)+1)

                            It is a sql script. If you were using MySQL I would say put it in a before Insert trigger, but mssql doesn't have those.
                            It could fit nicely in an after insert trigger.

                              Sometimes something kicks in after I submit a response.
                              This code could work if you really want to do it with xbasic.
                              To me, it makes more sense than keeping 26 separate tables or maintaining
                              26 different state variables.
                              Code:
                              dim ciCN as sql::connection
                              dim ciArgs as sql::arguments
                              dim idnum as c
                              ciArgs.set("cid",left(lastname,1))
                              ciCN.open(<sql connection>)
                              idnum = sql_lookup(ciCN,"<customerTable>","left(max(customerID),1)=:cid","format(right(max(customerID),5)+1),'0000#')",ciArgs)
                              customerID = left(lastName,1)+idnum
