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.

Is there a limit on the number of arguments for an SQL INSERT ?

  • Is there a limit on the number of arguments for an SQL INSERT ?

    I am trying to insert a single record into a MariaDB table using the INSERT command. Each record has 25 columns, the first being auto-increment. I follow the general format of:

    dim cn as SQL::Connection
    dim args as SQL::Arguments
    dim qry as c
    dim cl as l
    dim flag as l

    dim a_1 as C = "2020-10-27"
    dim a_2 as C = "2020-10-27"
    dim a_3 as C = "V3"
    dim a_23 as C = "V23"
    dim a_24 as C = "V24"

    cl = args.Clear()
    args.add("a_1", a_1)
    args.add("a_2", a_2)
    args.add("a_3", a_3)
    args.add("a_23", a_23)
    args.add("a_24", a_24)

    INSERT into table_data

    'open connection"{A5API=MariaDB,Server='',Port='3306',UserName='xxxx',Password='xxxx',database='main'}")
    'Execute insert
    flag = cn.Execute(qry,args)

    "flag" returns false and I get the following error message: = "One or more argument values were referenced in the SQL query, but were not found in the argument list"

    I have verified all arguments are being correctly assigned. The "qry" value is correct. The number of columns matches the query. The original query used the field names but for brevity I didn't show them here. Not specifying them is an option in MariaDB but the error is the same in both.

    I'm using Alpha V12 Build 7086 - the most recent.

    Any thoughts ?

    Never mind. Stupid mistake from working too late at night.

      One way to help spot this kind of (common) problem is to use debug, save_to_file() or some other method to see how the string looks.

      Use replace_arguments_in_string(qry, args) to help locate a problem like this pretty quickly.

      Also note the moderator edit to remove credentials from your connection string.
