Add ability to add comment to mapping ('COMMENT ON MAPPING ... IS ...')

[pavel-zotov]

Ticket was created after discussion with Alex.
Currently following script:

create or alter mapping lmap using plugin srp from user foo to user ltost;
comment on mapping lmap is 'test mapping,  do not delete';

-- issues:

Invalid token.
Dynamic SQL Error.
SQL error code = -104.
Token unknown - line 1, column 12.
mapping.

No backporting supposed for this issue - it requires new ODS, at least minor (i.e. 13.1 in FB5).

It seems that comment to MAPPING is not shown when we extract metadata as script vis 'isql -x'.

set bail on;
shell del c:\temp\tmp4test.fdb 2>nul;
create database 'localhost:c:\temp\tmp4test.fdb' user SYSDBA password 'masterkey';
commit;
show version;

recreate table test_tab(id int);
comment on table test_tab is 'Cu sea invenire appellantur.';

create or alter mapping test_map using plugin Srp from any user to user;
commit;
comment on mapping test_map is 'Lorem ipsum dolor sit amet.';
commit;

ISQL -X for database that is used in this script will show (at least on 5.0.0.958):

SET SQL DIALECT 3; 

/* CREATE DATABASE 'localhost:c:\temp\tmp4test.fdb' PAGE_SIZE 8192 DEFAULT CHARACTER SET NONE; */


COMMIT WORK;

/* Table: TEST_TAB, Owner: SYSDBA */
CREATE TABLE TEST_TAB (ID INTEGER);

/* Mapping security objects for this database */
CREATE MAPPING TEST_MAP USING PLUGIN SRP FROM ANY "USER" TO USER ;

/* Comments for database objects. */
COMMENT ON TABLE        TEST_TAB IS 'Cu sea invenire appellantur.';

(where is 'Lorem ipsum' here ?)

QA: test will be adjusted after issue about visibility of comments to mapping in 'isql -x' result will be fixed.

Shouldn't this be reopened while this finding is pending?
