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.

Removing a space from a field concatenation

  • Removing a space from a field concatenation

    I have a "full name" field which is a concatenation using a calculated field. The calculated field is as follows:
    iif(Company_Name = "", First_name + " " + Last_name, Company_Name + " " + First_name + " " + Last_name)
    The problem is if you enter lets say "John " for the first name (note the extra space after his name there!) and "Smith" for the last name you will get "John Smith" with an extra space in between the joined field - however the first name field does NOT include it when submitting so if you resave it you get "John Smith" without the extra space in it now.
    This is causing an issue later on when trying to find duplicates and or matching by name because the first time it is saved it includes that extra space, subsequent saves remove it since the single field FIRST NAME doesn't include the extra space at the end.

    So does anyone have any ideas on how I could best approach this problem? Ideally I would like to remove the trailing space, also I notice if you have a space prior to the data entry THAT does save in the database but trailing spaces do not. Again this is an issue because the concatenation saves the trailing space (and leading spaces) but the submittal to the database does not save the trailing space - but it does save leading space entry.

    I never thought about this as an issue but now it is...when I am creating a view in my DB the extra space in the name makes finding the match to group by and or sort impossible

    Hi Charles,
    how about an extra line
    of code
    Company_Name=strtran(Company_Name,”  “,” “)

      If I understand your question and if you're creating a calculated field in, say, a report:

      iif(alltrim(Company_Name) = "", alltrim(First_name) + " " + Last_name, Company_Name + " " + alltrim(First_name) + " " + Last_name)
      If you're doing this as a SQL database view, it'll be a little different but I don't know what database you're using.

        Hi Charles,

        How about this?

        iif(alltrim(Company_Name)<>"",alltrim(Company_Name)+" ","") + alltrim(iif(alltrim(First_name)<>"",alltrim(First_name) + " ","") + alltrim(Last_name)+" ")
        I put an alltrim around the first/last name concatenation, to handle a blank last name.

          Thanks guys - I actually implemented the alltrim function shortly after posting and that is what worked for me. Glad to see I was on the right (suggested) track here - I am concerned though about the fact that all trim will take ALL spaces rather than just trailing or preceding spaces as I noted a preceding space gets inserted while a trailing space does not when submitting data to the table. Still not sure how to properly handle that other than trim em all. So far it's been the habit of users (me included) to enter a space trailing the first name data entry and seems to be the current source of the issue solved by the alltrim function.

            ltrim() and rtrim() remove spaces from the left or right of the string.
            alltrim() removes spaces from the left and right of the string.
            remspecial() removes all non-alphanumeric characters from the string.

              So this script helps show the effects of each expression given the variations of the variables in the first 3 lines.

              The "|" and "|eon" (end of name) are included to help delineate the exact beginning and ending of the string.
              Change the spaces before and after in the variables to see the differences.

              The subtract sign used in a concatenation is similar to a rtrim()

              Company_Name = " Company_Name "
              First_name = " First_name "
              Last_name = " Last_name "
              myname1="|"+iif(alltrim(Company_Name)<>"",alltrim(Company_Name)+" ","") + alltrim(iif(alltrim(First_name)<>"",alltrim(First_name) + " ","") + alltrim(Last_name)+" ")+"|eon"
              myname2="|"+alltrim(alltrim(alltrim(Company_Name)+" "+alltrim(First_name)) + " "+ alltrim(Last_name)+" ")+"|eon"
              myname3="|"+Company_Name-" "+First_name - " "+ Last_name-" "-"|eon"

                Why bother with if statements?
                alltrim(alltrim(company_name)+" "+alltrim(first_name)+" "+alltrim(lastname))
                removes all leading, trailing & double spaces.

                  Hi Jon,
                  In this case, the final value changes depending on the value of Company.

                    On further review, I see I missed one of the alltrims.
