feat: Implement MARS-1409 post-hook for backfilling A_WORKFLOW_HISTORY_KEY
- Added .gitignore to exclude temporary folders. - Created SQL script to update existing A_WORKFLOW_HISTORY_KEY in A_SOURCE_FILE_RECEIVED. - Implemented rollback script to clear backfilled A_WORKFLOW_HISTORY_KEY values. - Added README.md for installation and usage instructions. - Developed master installation and rollback scripts for MARS-1409 post-hook. - Verified installation and rollback processes with detailed checks. - Updated trigger logic to manage workflow history updates. - Ensured proper version tracking and verification for related packages.

# MARS-1409-POSTHOOK: Backfill A_WORKFLOW_HISTORY_KEY for existing records
|
||||
|
||||
## Overview
|
||||
|
||||
Post-hook for MARS-1409. Backfills `A_WORKFLOW_HISTORY_KEY` in
|
||||
`CT_MRDS.A_SOURCE_FILE_RECEIVED` for historical records that existed before
|
||||
MARS-1409 was installed.
|
||||
|
||||
Matches records by `SOURCE_FILE_NAME` against `file$name` in the corresponding
|
||||
ODS table (`ODS.<TABLE_ID>_ODS`) for each `INPUT` source configuration.
|
||||
|
||||
## Contents
|
||||
|
||||
| File | Description |
|
||||
|------|-------------|
|
||||
| `install_mars1409_posthook.sql` | Master installation script (SPOOL, ACCEPT, quit) |
|
||||
| `rollback_mars1409_posthook.sql` | Master rollback script (SPOOL, ACCEPT, quit) |
|
||||
| `01_MARS_1409_POSTHOOK_update_existing_workflow_keys.sql` | Backfill UPDATE script |
|
||||
| `91_MARS_1409_POSTHOOK_rollback_workflow_keys.sql` | Clear backfilled values |
|
||||
| `track_package_versions.sql` | Universal version tracking (no packages changed) |
|
||||
| `verify_packages_version.sql` | Universal package verification |
|
||||
| `README.md` | This file |
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- MARS-1409 installed (`A_WORKFLOW_HISTORY_KEY` column must exist in `CT_MRDS.A_SOURCE_FILE_RECEIVED`)
|
||||
- ODS tables populated with ingested data
|
||||
- ADMIN user with access to CT_MRDS and ODS schemas
|
||||
|
||||
## Installation
|
||||
|
||||
```powershell
|
||||
# Execute as ADMIN user
|
||||
Get-Content "MARS_Packages/REL02_POST/MARS-1409-POSTHOOK/install_mars1409_posthook.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
|
||||
```
|
||||
|
||||
Log file created automatically: `log/INSTALL_MARS_1409_POSTHOOK_<PDB>_<timestamp>.log`
|
||||
|
||||
## What it does
|
||||
|
||||
- Iterates all `INPUT` source configurations from `CT_MRDS.A_SOURCE_FILE_CONFIG`
|
||||
- For each config, joins `A_SOURCE_FILE_RECEIVED` with `ODS.<TABLE_ID>_ODS` on `SOURCE_FILE_NAME = file$name`
|
||||
- Updates `A_WORKFLOW_HISTORY_KEY` for records with statuses:
|
||||
`VALIDATED`, `READY_FOR_INGESTION`, `INGESTED`, `ARCHIVED`, `ARCHIVED_AND_TRASHED`, `ARCHIVED_AND_PURGED`
|
||||
- Skips configs with no NULL records or missing ODS tables
|
||||
- Prints summary with counts per config and overall totals
|
||||
|
||||
## Rollback
|
||||
|
||||
```powershell
|
||||
# Execute as ADMIN user
|
||||
Get-Content "MARS_Packages/REL02_POST/MARS-1409-POSTHOOK/rollback_mars1409_posthook.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
|
||||
```
|
||||
|
||||
Rollback clears all non-NULL `A_WORKFLOW_HISTORY_KEY` values from `A_SOURCE_FILE_RECEIVED`.
|
||||
The trigger installed by MARS-1409 will repopulate new records automatically.
