## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [MEDICARE_BENEFICIARY_QUERY_BAT](../database-tables.md#medicare_beneficiary_query_bat) | SELECT (outer + correlated-free subquery) | SUBMISSION_DATE, UPDATE_NUM, RESPONSE_DATE, SUBMITTED_WORKER_COUNT, MATCHED_WORKER_COUNT, UPDATE_USER, UPDATE_DATE |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Claims/MedicareQueryProvider.cs:24-25`. The repository/queryable is initialised at `Data/SAIF.Data/Queries/Claims/MedicareQueryProvider.cs:17`.

```csharp
// Data/SAIF.Data/Queries/Claims/MedicareQueryProvider.cs:17
medicareBatchRepository = factory.GetRepository<MedicareBeneficiaryQueryBatch>().Query();

// Data/SAIF.Data/Queries/Claims/MedicareQueryProvider.cs:24-25
public MedicareBeneficiaryQueryBatch GetNextMinumumSubmissionBatch()
{
    var medicarehold = medicareBatchRepository.Where(s => s.ResponseDate != null);
    return medicareBatchRepository.SingleOrDefault(x => x.SubmissionDate == medicarehold.Min(d => d.SubmissionDate));
}
```

## 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
  MBQB.SUBMISSION_DATE,
  MBQB.UPDATE_NUM,
  MBQB.RESPONSE_DATE,
  MBQB.SUBMITTED_WORKER_COUNT,
  MBQB.MATCHED_WORKER_COUNT,
  MBQB.UPDATE_USER,
  MBQB.UPDATE_DATE
FROM MEDICARE_BENEFICIARY_QUERY_BAT MBQB
WHERE MBQB.SUBMISSION_DATE = (
  SELECT MIN(MBQB2.SUBMISSION_DATE)
  FROM MEDICARE_BENEFICIARY_QUERY_BAT MBQB2
  WHERE MBQB2.RESPONSE_DATE IS NOT NULL
)
-- SingleOrDefault: NHibernate expects at most one row
```

Translation notes:
- `medicarehold` is an un-materialized `IQueryable`. Using `medicarehold.Min(m => m.BatchNumber)` inside the outer lambda makes NHibernate emit it as a scalar subquery; it is not a separate round trip.
- `SubmissionDate` is the entity Id (`Id(x => x.SubmissionDate).Column("SUBMISSION_DATE")`).
