Ran the new tvc snippet on a simple table with a Birth Date [Date] column and got the following output in the @tmp:

Birth Date date NULL,

Maybe there need to be a QUOTENAME() somewhere?

    Yep, this seems to fix it for me:


  • Thanks for your feedback, I have spoken with Phil Factor, the creator of that Snippet who confirms that this can be an issue in columns with illegal characters and that your workaround is a good solution. I am going to escalate this to the development team to see if we can change this.

  • This should do it. Sorry about the quotename stuff. I hardly ever  seem to use columns with illegal characters in them. I meant to add something clever that added the quotes only when necessary but never got around to it.
    This should work nicely
