## LINQ statement

Source: `Data/SAIF.Data/Queries/Claims/Ebilling/EbillDocumentQueryProvider.cs:22`. The repository is obtained at `Data/SAIF.Data/Queries/Claims/Ebilling/EbillDocumentQueryProvider.cs:16`.

```csharp
// Data/SAIF.Data/Queries/Claims/Ebilling/EbillDocumentQueryProvider.cs:16
_repository = Factory.GetRepository<EbillDocument>().Query();

// Data/SAIF.Data/Queries/Claims/Ebilling/EbillDocumentQueryProvider.cs:22
return _repository.Single(doc => doc.Id == documentId);
```

## 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
  ED.EBILL_DOCUMENT_SEQ_NUM,
  ED.UPDATE_NUM,
  ED.EBILL_DOCUMENT_SUB_NUM,
  ED.EBILL_DOCUMENT_CONTROL_NUM,
  ED.IMAGE_SEQ_NUM,
  ED.UPDATE_USER,
  ED.UPDATE_DATE,
  ED.EBILL_SEQ_NUM,
  ED.EBILL_DOCUMENT_TYPE_CODE
FROM EBILL_DOCUMENT ED
WHERE ED.EBILL_DOCUMENT_SEQ_NUM = :documentId
-- NHibernate expects at most one row
```

Translation notes:

- `Single()` throws when no row, or more than one row, is returned.
