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.

    Error in SQL Select statement with argument (querying effective dated row)

    Hi. I am having a problem using the argument in my sql select statement. I have document templates with different versions. Defending on the Budget Begin Date, I would like to use the latest version of the template where its effective date is <= vBudgetBeginDt.

    SELECT * FROM dbo.DocTemplates WHERE TemplateID = 1 AND Effectivedt = (SELECT Max(dbo_DocTemplates.Effectivedt) AS MaxofEffectivedt FROM dbo.DocTemplates dbo_DocTemplates WHERE TemplateID = '1' AND EffectiveDt <= convert(datetime, :vBudgetBeginDt, 101))

    On the Edit Ad Hoc DataSource window, it works fine when I click the Preview Data and enter the budget begin date; I get the correct effective dated row. However, when I click Finish button, it gives me the error:
    Conversion failed when converting date and/or time from character string. SQL State is: 22007.

    Screenshot attached.

    How come A5 understands this sql statement when previewing data (Preview Data button) and yet it will not allow me to save or click the Finish button? Please help. How should I use the argument here?

    Thanks.
    Hector

    Don't your argument have to be of type Date, I assume that Alpha is doing the conversion in the preview, but on the actual execution, you have to make sure the types are correct

      Thanks for you input, Jim.
      My argument was a date when I tried it the first time but I was getting an error "Function requested is not supported" (see attached screenshot).

        Re: Error in SQL Select statement with argument (querying effective dated row)

        The function requested not supported error occurs because you are using what appears to be a SQL Server native functions (max() and convert()), but have specified Portable syntax in the builder. Change the syntax to "Native" and the builder should allow the function, and the select statement should parse.

          Hi Jerry. I followed your advice (see screenshots below one with arg with Character and one with Date type). However, I am still getting the errors.

          Is there any other way I could make this thing work? I just want to get the last valid effective dated row so that my report can use the correct template depending on the Budget Begin Date value.

          Thanks. I appreciate your help.

          EDITED POST 08/27/2013 5:35pm:

          I would like to add that when I hardcode the date like the one below works fine using both Portable or Native syntax.
          SELECT * FROM dbo.DocTemplates WHERE TemplateID = 1 AND Effectivedt = (SELECT Max(dbo_DocTemplates.Effectivedt) AS MaxofEffectivedt FROM dbo.DocTemplates dbo_DocTemplates WHERE TemplateID = '1' AND EffectiveDt <= convert(datetime, '01/01/2013', 101) )

          I've tried many different things including enclosing the arg inside curly brackets but I got an error "One or more argument values were referenced in the SQL query, but were not found in the argument list" even if it is defined in the argument list... so not sure what the curly brackets do in this case but at least A5 recognized that there is an arg in the statement.

          I changed vBudgetBeginDt to Type=Date and I tried this sql:
          SELECT * FROM dbo.DocTemplates WHERE TemplateID = 1 AND Effectivedt = :vBudgetBeginDt

          and got this weird error message when clicked the "Preview Data":
          Could not execute query against Database. Error reported was: Success

          and when I clicked Finish, got this error:
          Function requested is not supported

          ...which makes me wonder and leads me to ask a simple question. How do I filter a date field in an ms-sql table using an argument?

          EffectiveDt field in sql table had data type of smalldatetime at first, but also tried data type of date; both have same issue.

          I'm taking so much time solving this one. I appreciate any help on this.

          Thanks.

            Re: Error in SQL Select statement with argument (querying effective dated row)

            After long hours of trial and error trying to make this rather simple Select statement to work, I thought of changing the name of my argument so I went to Add Argument dialog box to create a new one. Right before I click the OK button I noticed the 'Tips'... and read/comprehend this time. The tip says:

            'Date' type is only for 'Date' fields in Alpha Five .dbf tables.
            For 'Date/time' or 'Time' fields in SQL tables, select the 'Time' type.

            I wouldn't think about that the first time I set up my arg. IMO, I think instead of a "Tips" label, it should have a label of "IMPORTANT" since this is really important to be noticed (perhaps in bold, red, blinking... kiddin').

            I changed my arg to Time and it worked with both Portable and Native sql syntax.

            Thanks all for helping. I'm posting my solution/experience here hoping to benefit others and A5 newcomers like me. Read the Tips!
