# title:        execute statement ignores the text of the SQL-query after a comment of the form "-"
# decription:   
#                  We concatenate query from several elements and use '
#               ' delimiter only to split this query into lines.
#                  Also, we put single-line comment in SEPARATE line between 'select' and column/value that is obtained from DB.
#                  Final query will lokk like this (lines are separated only by SINGLE delimiter, ascii_char(13), NO '
#               ' here!):
#                  ===
#                      select
#                      -- comment N1
#                      'foo' as msg'
#                      from
#                      -- comment N2
#                      rdb$database
#                  ===
#                  This query should NOT raise any exception and must produce normal output (string 'foo').
#                  Thanks to hvlad for suggestions.
