Issue: like-wildcard-adjacent

Hi,

regarding the grammar for DAV:like ([1]):

a) This seems to imply that "__" (to match any two-character sequence) is
not allowed. Does anybody remember why one would want that?

b) Another thing I'd like to see clarified: Is it allowed to use "\" to
escape characters other than "\", "%" and "_"? What does ANSI SQL say about
this?


Could please somebody with access to the ANSI SQL spec check this for me?

Regards, Julian
