    Incorrect syntax near '?'.

    Msg 156, Level 15, State 1, Line 26

    Incorrect syntax near the keyword 'as'.

    Something weird is happening with hidden characters in the site's text box control. I copy-pasted the script and had to delete a bunch of white space to get it to work (even though it looks the same).

    Try this version:

    /*

    This query gets all queries, their query plans, and all indexes included in those plans.

    isn't there a way to edit submitted queries? I'm a little confused by my start to using this addin, as not sure if there are "updates". Gist's are version controlled, and not sure if anyway to see this with sql scripts using this tool?
