'v2.6.3 (2026-01-28): COMPILATION FIX - Resolved ORA-00904 error in EXPORT_PARTITION_PARALLEL. SQLERRM and DBMS_UTILITY.FORMAT_ERROR_BACKTRACE cannot be used directly in SQL UPDATE statements. Now properly assigned to vgMsgTmp variable before UPDATE.' || CHR(10) ||
|
||||
'v2.6.2 (2026-01-28): CRITICAL FIX - Race condition when multiple exports run simultaneously. Changed DELETE to filter by age (>24h) instead of deleting all COMPLETED chunks. Prevents concurrent sessions from deleting each other chunks. Session-safe cleanup with TASK_NAME filtering. Enables true parallel execution of multiple export jobs.' || CHR(10) ||
|
||||
'v2.6.1 (2026-01-28): Added DELETE_FAILED_EXPORT_FILE procedure to clean up partial/corrupted files before retry. When partition fails mid-export, partial file is deleted before retry to prevent Oracle from creating _1 suffixed duplicates. Ensures clean retry without orphaned files in OCI bucket.' || CHR(10) ||
|
||||
'v2.6.0 (2026-01-28): CRITICAL FIX - Added STATUS tracking to A_PARALLEL_EXPORT_CHUNKS table to prevent data duplication on retry. System now restarts ONLY failed partitions instead of re-exporting all data. Added ERROR_MESSAGE and EXPORT_TIMESTAMP columns for better error handling and monitoring. Prevents duplicate file creation when parallel tasks fail (e.g., 22 partitions with 16 threads, 3 failures no longer duplicates 19 successful exports).' || CHR(10) ||
|
||||
'v2.5.0 (2026-01-26): Added recorddelimiter parameter with CRLF (CHR(13)||CHR(10)) for CSV exports to ensure Windows-compatible line endings. Improves cross-platform compatibility when CSV files are opened in Windows applications (Notepad, Excel).' || CHR(10) ||
|
||||
'v2.4.0 (2026-01-11): Added pTemplateTableName parameter for per-column date format configuration. Implements dynamic query building with TO_CHAR for each date/timestamp column using FILE_MANAGER.GET_DATE_FORMAT. Supports 3-tier hierarchy: column-specific, template DEFAULT, global fallback. Eliminates single dateformat limitation of DBMS_CLOUD.EXPORT_DATA.' || CHR(10) ||
|
||||
'v2.3.0 (2025-12-20): Added parallel partition processing using DBMS_PARALLEL_EXECUTE. New pParallelDegree parameter (1-16, default 1) for EXPORT_TABLE_DATA_BY_DATE and EXPORT_TABLE_DATA_TO_CSV_BY_DATE procedures. Each year/month partition processed in separate thread for improved performance.' || CHR(10) ||
|
||||
'v2.2.0 (2025-12-19): DRY refactoring - extracted shared helper functions (sanitizeFilename, VALIDATE_TABLE_AND_COLUMNS, GET_PARTITIONS, EXPORT_SINGLE_PARTITION worker procedure). Reduced code duplication by ~400 lines. Prepared architecture for v2.3.0 parallel processing.' || CHR(10) ||
|
||||
'v2.1.1 (2025-12-04): Fixed JOIN column reference A_WORKFLOW_HISTORY_KEY -> A_ETL_LOAD_SET_KEY, added consistent column mapping and dynamic column list to EXPORT_TABLE_DATA procedure, enhanced DEBUG logging for all export operations' || CHR(10) ||

* @desc Exports data to a single CSV file with date filtering.
|

* Unlike EXPORT_TABLE_DATA_BY_DATE, this procedure creates one CSV file
|

* instead of multiple Parquet files partitioned by year/month.
|
||||
* Uses the same date filtering mechanism with CT_ODS.A_LOAD_HISTORY.
|
||||
* Allows specifying custom column list or uses T.* if pColumnList is NULL.
|
||||
* Validates that all columns in pColumnList exist in the target table.
|
||||
* Automatically adds 'T.' prefix to column names in pColumnList.
|
||||
* @example
|
||||
* begin
|
||||
* DATA_EXPORTER.EXPORT_TABLE_DATA_TO_CSV_BY_DATE(
|
||||
* pSchemaName => 'CT_MRDS',
|

* Unlike EXPORT_TABLE_DATA_BY_DATE, this procedure creates one CSV file

* Allows specifying custom column list or uses T.* if pColumnList is NULL.
|
||||
* Validates that all columns in pColumnList exist in the target table.
|
||||
* Automatically adds 'T.' prefix to column names in pColumnList.

* @example
|
