id UUID PRIMARY KEY,
|
|
ensemble_action TEXT, -- ❌ "BUY", "SELL", "HOLD" (string)
|
|
-- ...
|
|
);
|
|
|
|
-- String validation at runtime
|
|
SELECT * FROM ensemble_predictions
|
|
WHERE ensemble_action = 'BUY'; -- ❌ Typo-prone ("buy" vs "BUY")
|
|
```
|
|
|
|
### AFTER: Enum-based (Type-Safe)
|
|
|
|
```sql
|
|
-- Migration: Add 'hold' to order_side enum
|
|
ALTER TYPE order_side ADD VALUE 'hold';
|
|
|
|
CREATE TABLE ensemble_predictions (
|
|
id UUID PRIMARY KEY,
|
|
ensemble_action order_side, -- ✅ Enum: {buy, sell, hold}
|
|
-- ...
|
|
);
|
|
|
|
-- Type-safe enum validation at database level
|
|
SELECT * FROM ensemble_predictions
|
|
WHERE ensemble_action = 'hold'; -- ✅ Database validates enum value

|
└─ Update SQLX offline data
|
|
|
|
Phase 6: Tests (2h)
