-- MARS-1005-PREHOOK INSTALL SCRIPT: Fix DATA_EXPORTER RFC 4180 Compliance
|
|
-- ===================================================================
|
|
-- Purpose: Pre-hook for MARS-1005 - Deploy updated DATA_EXPORTER (v2.15.0)
|
|
-- that exports CSV files in RFC 4180 compliant format.
|
|
-- Background: DATA_EXPORTER v2.14.0 uses escape=true in DBMS_CLOUD.EXPORT_DATA,
|
|
-- which produces backslash-escaped embedded quotes (\")
|
|
-- instead of RFC 4180 doubling ("").
|
|
-- ODS external tables (FIELDS CSV WITHOUT EMBEDDED) expect RFC 4180.
|
|
-- Fix: remove escape=true so Oracle uses RFC 4180 doubling.
|
|
-- Author: Grzegorz Michalski
|
|
-- Date: 2026-03-10
|
|
|
|
-- Dynamic spool file generation (using SYS_CONTEXT - no DBA privileges required)
|
|
-- Log files are automatically created in log/ subdirectory
|
|
-- IMPORTANT: Ensure log/ directory exists before SPOOL (use host mkdir)
|
|
host mkdir log 2>nul

PROMPT Problem: DATA_EXPORTER v2.14.0 uses escape=true in DBMS_CLOUD.EXPORT_DATA
|
|
PROMPT which causes backslash-escaped embedded quotes (\")
|
|
PROMPT instead of RFC 4180 doubling (""). ODS external tables with
|
|
PROMPT FIELDS CSV WITHOUT EMBEDDED reject rows with backslash-escape.

PROMPT This script will:
|
|
PROMPT - Deploy CT_MRDS.DATA_EXPORTER v2.15.0 (removes escape=true parameter)
|
|
PROMPT - Exported CSV files will use RFC 4180 doubling ("") for embedded quotes
|
|
PROMPT - ODS external tables (FIELDS CSV WITHOUT EMBEDDED) are NOT modified
