Please give me a URL of a page where I can find a formal criterion that helps me determine if the string can or cannot be used instead of <<NAME>> placeholders in here:
SELECT <<NAME>> as <<NAME>> FROM <<NAME>> as <<NAME>>

I am talking about MS JET SQL.

Thanks,
--Igor

Igor,

It really does not have to be hard: use only letters, numbers, and underscores.  Some Experts even eschew
underscores.  Further, avoid reserved words: SELECT, UPDATE, Date, Format, any of the key commands
in SQL or names of functions.

OK, I know that the following strings CAN be used as object names:
[Select], [My table], [Include?]
I am not sure about a name with the length, say, 500 characters; or about
__table_name__
and so on.
My program has to determine if a string will be later accepted by JET engine. It (the program) just wants to follow a set of "formal" rules to be able to point user to a right direction to meet these rules.
Please try to help me one more time. (The list of key words looks irrelevant to the issue).

Looks closer to what I need. It's at least a document to refer to. But it's not exactly what I am looking for:
Please see the title of my question. It implies more than just max length.

capricorn1, specifications you are referring to instruct me that max length of the name is 64.
It does not say whether the following sequences of character are valid sql names:
SELECT
      ["How are you doing?" - John asked]
FROM [I am all right. Thanks.]  
ORDER BY [order by]
And I am looking for a document that explicitly states what... see the title of my question.

Have a look at http://msdn.microsoft.com/en-us/library/ms189822.aspx for reserved words.  There is such a wide variety of naming conventions it is probably best to Google - MS SQL naming conventions.

Yes, thanks, it is the best answer although it's not exactly what the rules should be. This however is a usual blunder of MS, not of yours, capricorn1.
