# 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.
#
# Confirmed bug on:
# 3.0.4.32924
# 4.0.0.918
# -- got:
# Error while preparing SQL statement:
# - SQLCODE: -104
# - Dynamic SQL Error
# - SQL error code = -104
# - Unexpected end of command - line 1, column 1
