# Walkthrough - Fixing PostgreSQL Compatibility
|
||
|
|
|
||
|
|
I have resolved the SQL errors occurring in the Loss Profit History module when running on PostgreSQL.
|
||
|
|
|
||
|
|
## Changes Made
|
||
|
|
|
||
|
|
### Business Module Controllers
|
||
|
|
- **[AcnooLossProfitHistoryController.php](file:///media/itc43/Data/OTHER_PROJECT/kulakpos/kulakpos_15Maret2026_to%20GTEA/public_html/Modules/Business/App/Http/Controllers/AcnooLossProfitHistoryController.php)**:
|
||
|
|
- Quoted `saleDate`, `lossProfit`, `incomeDate`, `expenseDate`, and `date` columns in all `DB::raw` expressions.
|
||
|
|
- Changed double quotes (`"`) to single quotes (`'`) for string literals (`'positive'`, `'negative'`) in `CASE` statements.
|
||
|
|
- **[AcnooLossProfitHistoryReportController.php](file:///media/itc43/Data/OTHER_PROJECT/kulakpos/kulakpos_15Maret2026_to%20GTEA/public_html/Modules/Business/App/Http/Controllers/AcnooLossProfitHistoryReportController.php)**:
|
||
|
|
- Applied identical fixes for PostgreSQL compatibility.
|
||
|
|
- **[AcnooProductLossProfitReportController.php](file:///media/itc43/Data/OTHER_PROJECT/kulakpos/kulakpos_15Maret2026_to%20GTEA/public_html/Modules/Business/App/Http/Controllers/AcnooProductLossProfitReportController.php)**:
|
||
|
|
- Quoted `lossProfit` in `CASE` statements.
|
||
|
|
|
||
|
|
### Export Classes
|
||
|
|
- **[ExportLossProfitHistory.php](file:///media/itc43/Data/OTHER_PROJECT/kulakpos/kulakpos_15Maret2026_to%20GTEA/public_html/Modules/Business/App/Exports/ExportLossProfitHistory.php)**:
|
||
|
|
- Fixed column quoting and string literals for Excel/CSV exports.
|
||
|
|
- **[ExportProductLossProfit.php](file:///media/itc43/Data/OTHER_PROJECT/kulakpos/kulakpos_15Maret2026_to%20GTEA/public_html/Modules/Business/App/Exports/ExportProductLossProfit.php)**:
|
||
|
|
- Fixed column quoting in `CASE` statements for product loss/profit exports.
|
||
|
|
|
||
|
|
## Verification Results
|
||
|
|
- The code changes directly address the `SQLSTATE[42703]` (Undefined column) error by ensuring PostgreSQL recognizes the mixed-case column names.
|
||
|
|
- String literal fixes prevent PostgreSQL from interpreting `'positive'` and `'negative'` as column names.
