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.

    <<%sq %sql% xBasic continuation

    Could some one, please, tell how this command works? How I can find it in the xBasic documentation.

    I can't search for it.

    What if I wanted to embedded a value from a variable.

    For example.

    If I want
    sqlStatement = "select * from customer where name = '"+variable+"'"

    can I do this?

    sqlStatement =<<%sql%
    select * from customer where name = '<<variable>>'

    If there are any VFP programmers here, is the << like text/endtext?

    Also, is this correct...
    sqlStatement = "select * from customer where name = '"+ \

    I'm new to xBasic and don't know the basics. And searching google or the wiki for these characters (<< % \) is pointless.

    Re: &lt;&lt;%sq %sql% xBasic continuation

    You need construct as you have done and then replace the <<variable>> with its current equivalent.

    Illustrating in the interactive.

    variable = "Test_value"
    sqlStatement =<<%sql% 
    select * from customer where name = '<<variable>>'
    ? sqlStatement 'this isn't working
    = select * from customer where name = '<<variable>>'
    sqlStatement = strtran(sqlStatement,"<<variable>>",variable)
    ? sqlStatement 'now it does
    = select * from customer where name = 'Test_value'
    See the documentation for the word backslash.
    There can be only one.


      Re: &lt;&lt;%sq %sql% xBasic continuation

      Thank you.


        Re: &lt;&lt;%sq %sql% xBasic continuation

        Thank you.


          Re: &lt;&lt;%sq %sql% xBasic continuation


          You cannot include a backslash in an sql statement (someone else asked that a week ago), so your last example on the first post will not work.

          Here are the three ways I use vars in an sql statement. Where they exist, I put the single quotes in red so they stand out. If the variable is a numeric, omit the single quotes.

          var1 = "steve"
          dim cn as sql::connection
"::name::conn") ' where conn is the connection string name

          1) simple substitution
          vsql = "SELECT * FROM customer where firstname = '" + var1 + "'"

          2) arguments
          dim args as sql::arguments
          vsql = "SELECT * FROM customer where firstname = :firstname"

          3) evaluate - replace vars in curly brackets with their value
          vsql = "SELECT * FROM customer where firstname = '{var1}'"
          vsql = evaluate_string(vsql)

          4) string replace, Stan's suggestion, using my syntax
          vsql = "SELECT * FROM customer where firstname = '<<var1>>'"
          vsql = stritran(vsql,"<<var1>>",var")

          All but the first one works if you use delimiters, like:

          vsql = <<%txt%
          SELECT * FROM customer where firstname = '{var1}'
          vsql = evaluate_string(vsql)

            A complex system that does not work is invariably found to have evolved from a simpler system that worked just fine.
