MARS-1056: Master Installation Script for VARCHAR2 Definition Fixes
|
|
Author: Grzegorz Michalski
|
|
Date: November 25, 2025
|
|
Purpose: Main installation script for VARCHAR2 definition fixes in external tables
|
|
|
|
PROBLEM:
|
|
FILE_MANAGER.GENERATE_EXTERNAL_TABLE_PARAMS uses data_length instead of char_length
|
|
for VARCHAR2 columns, causing incorrect definitions in external tables.
|
|
|
|
SOLUTION:
|
|
Modify column definition generation logic to preserve CHAR/BYTE semantics
|
|
from template tables.
|
|
|
|
USAGE:
|
|
sql 'CT_MRDS/Cloudpass#34@ggmichalski_high' '@install_mars1056.sql'
|
|

PROMPT Installation will:

PROMPT 2. Track package version
|
|
PROMPT 3. Verify all tracked packages

PROMPT

PROMPT VARCHAR2 definition fixes have been implemented:
|
|
PROMPT - GENERATE_EXTERNAL_TABLE_PARAMS now preserves CHAR/BYTE semantics
|
|
PROMPT - External tables will match template table definitions
|
|
PROMPT - Test results shown above should indicate SUCCESS
|
|
PROMPT
|
|
PROMPT Next steps:
|
|
PROMPT 1. Verify test results above show all SUCCESS indicators
|
|
PROMPT 2. Test external table creation with various templates
|
|
PROMPT 3. Monitor for any issues with existing processes
|
|
PROMPT 4. If problems occur, use rollback_mars1056.sql
