Created attachment 75342
  --> https://bugs.freedesktop.org/attachment.cgi?id=75342&action=edit
typescript with warnings

The referenced warning message has been mentioned in 

    bug 60504 "EDITING: Sort removes brackets in Queries - Sorting
      doesn't work in correlated Subqueries"

    bug 60539 "FILESAVE: Column-width of a Query couldn't be saved"

    bug 61203 "SQL syntax error inserting new record into empty table"

I am creating this report to deal with the possibility that it is
independent of those other problems.


steps to reproduce ...

(1) Download the .odb file attached to bug 61193
    <https://bugs.freedesktop.org/attachment.cgi?id=75216>.

(2) At command line, open the file.

    Program displays window "New Database1.odb"

(3) In the left pane, click <Tables>.

    Program displays table name OneColumn in the lower right pane.

(4) In the lower right pane right-click OneColumn and on the pop-up
    menu select Open.

    Program displays Table Data View window.  In the terminal window,
    observe numerous warnings like the following, but with an
    assortment of _nRule's ...

       
warn:connectivity.parse:1104:1:workdir/unxlngi6/YaccTarget/connectivity/source/parse/sqlbison.cxx:9223:
connectivity::OSQLParser::RuleIDToRule cannot reverse-lookup rule. Reverse
mapping incomplete? _nRule='383' yytname[_nRule]='opt_fetch_first_clause'


The attached typescript has 77 instances of the warning.  Doing some
counting gives us ...

    _nRule  times  yytname[_nRule]
    ------  -----  ------------------------
       367     15  opt_all_distinct
       378     10  opt_result_offset_clause
       383     10  opt_fetch_first_clause
       387     10  opt_limit_offset_clause
       398     10  opt_group_by_clause
       400     10  opt_having_clause
       418      2  null_predicate_part_2
       489     10  opt_window_clause


I observed this with master commit 2e367c0, pulled around 2013-02-17,
built and running on ubuntu-natty (11.04) 32-bit.  My configuration
options are ...

    --enable-dbgutil
    --enable-crashdump
    --disable-build-mozilla
    --without-system-postgresql
    --without-myspell-dicts
    --without-help
    --with-extra-buildid
