```csharp
// Data/SAIF.Data/Queries/Claims/Ebilling/EbillQueryProvider.cs:33
billAssignmentRepository = Factory.GetRepository<EbillAssignmentRule>().Query();

// Data/SAIF.Data/Queries/Claims/Ebilling/EbillQueryProvider.cs:269
return billAssignmentRepository.SingleOrDefault(x => x.RuleCode == ruleCode);
```

## Sample SQL

> **Inferred SQL:** This SQL was inferred from the LINQ statement above and the NHibernate mappings. It is not concrete SQL from source code; NHibernate generates the executed statement at runtime, so aliases, column order, join syntax, and bind-parameter names may differ.

```sql
-- Inferred from LINQ (NHibernate mapping translation); not concrete SQL
SELECT
  EAR.EBILL_ASSIGNMENT_RULE_SEQ_NUM,
  EAR.UPDATE_NUM,
  EAR.EBILL_ASSIGNMENT_RULE_CODE,
  EAR.RESPONSIBLE_PARTY_ID,
  EAR.UPDATE_USER,
  EAR.UPDATE_DATE,
  EAR.CBP_BILL_STATUS_CODE
FROM EBILL_ASSIGNMENT_RULE EAR
WHERE EAR.EBILL_ASSIGNMENT_RULE_CODE = :ruleCode
-- NHibernate expects at most one row
```

Translation notes:

- Direct translation: an equality predicate on mapped columns. No navigation, joins or in-memory operators.
