    Missing IN or OUT parameter at index:: 1

      I don't know if this is a known bug or not.  But, I'll figured I'd post up my test-case to see if it is me or something else.


      I was trying to insert a large text string using the q'[]' notation.  Normally, that works.


      But, with one particular string, I got this error: "Missing IN or OUT parameter at index:: 1".


      I narrowed the problem down to this string format failing:

      select q'[]]:a]'
      from dual;


      The 'a' can be any alpha-numereic.  Although, I haven't tried everything.

      It seems there can be an arbitrary amount of extra characters between every thing except the two closing square brackets

      eg: this still fails

      select q'[ ]] :  a   ]'
      from dual;

      Which causes this regex string to fail

      select q'[[[:digit:]][[:alpha:]]]'
      from dual;



      use q'{}' syntax ( curly brackets) instead. Actually, anything BUT square brackets. even q'z]]:a]z' works.
