## LINQ statement

Source: `Data/SAIF.Data/Queries/Claims/MedicareQueryProvider.cs:59`. The repository/queryable is initialised at `Data/SAIF.Data/Queries/Claims/MedicareQueryProvider.cs:18`.

```csharp
// Data/SAIF.Data/Queries/Claims/MedicareQueryProvider.cs:18
medicareBeneficiaryRepository = factory.GetRepository<MedicareBeneficiaryQuery>().Query();

// Data/SAIF.Data/Queries/Claims/MedicareQueryProvider.cs:59
public IEnumerable<MedicareBeneficiaryQuery> GetBeneficiaries(DateTime submissionDateTime)
{
    return medicareBeneficiaryRepository.Where(x => x.SubmissionDate == submissionDateTime);
}
```

## 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
  MBQ.MEDICARE_QUERY_SEQ_NUM,
  MBQ.UPDATE_NUM,
  MBQ.PERSON_ID,
  MBQ.SUBMISSION_DATE,
  MBQ.MEDICARE_CLAIM_NUMBER,
  MBQ.TAX_ID,
  MBQ.LAST_NAME,
  MBQ.FIRST_INITIAL,
  MBQ.GENDER_CODE,
  MBQ.BIRTH_DATE,
  MBQ.MEDICARE_BENEFICIARY_FLAG,
  MBQ.RESPONSE_MEDICARE_CLAIM_NUMBER,
  MBQ.RESPONSE_TAX_ID,
  MBQ.RESPONSE_LAST_NAME,
  MBQ.RESPONSE_FIRST_INITIAL,
  MBQ.RESPONSE_GENDER_CODE,
  MBQ.RESPONSE_BIRTH_DATE,
  MBQ.UPDATE_USER,
  MBQ.UPDATE_DATE,
  MBQ.PRIMARY_TAX_ID_FLAG
FROM MEDICARE_BENEFICIARY_QUERY MBQ
WHERE MBQ.SUBMISSION_DATE = :submissionDateTime
```

Translation notes:
- The query is deferred; it runs when the caller enumerates it.
