## LINQ statement

Source: `Data/SAIF.Data/Queries/Claims/EbillingQueryProvider.cs:141`. The repository is obtained at `Data/SAIF.Data/Queries/Claims/EbillingQueryProvider.cs:39`.

```csharp
// Data/SAIF.Data/Queries/Claims/EbillingQueryProvider.cs:39
clearinghouses = factory.GetRepository<EbillClearinghouse>().Query();

// Data/SAIF.Data/Queries/Claims/EbillingQueryProvider.cs:141
return clearinghouses.FirstOrDefault(x => x.EndDate == null);
```

## 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 *
FROM (
  SELECT
    EC.EBILL_CLEARINGHOUSE_SEQ_NUM,
    EC.UPDATE_NUM,
    EC.CLEARINGHOUSE_NAME,
    EC.CLEARINGHOUSE_TAX_ID,
    EC.BEGIN_DATE,
    EC.END_DATE,
    EC.PAYER_USER_ID,
    EC.PAYER_NAME,
    EC.PAYER_TAX_ID,
    EC.REPETITION_SEPARATOR,
    EC.ELEMENT_DELIMITER,
    EC.VERSION_CONTROL_NUM,
    EC.BUSINESS_PHONE_NUM,
    EC.TECH_SUPPORT_PHONE_NUM,
    EC.SAIF_EOB_RULE_URL_ADDR,
    EC.UPDATE_USER,
    EC.UPDATE_DATE,
    EC.MCO_ADJUSTMENT_REASON_CODE,
    EC.MCO_ADJUSTMENT_GROUP_CODE,
    EC.MCO_REMITTANCE_ADVICE_CODE,
    EC.TRANSACTION_FEE_AMT,
    EC.CLEARINGHOUSE_CODE,
    EC.SAIF_LOC_SEQ_NUM
  FROM EBILL_CLEARINGHOUSE EC
  WHERE EC.END_DATE IS NULL
)
WHERE ROWNUM <= 1
```

Translation notes:
- Oracle10 row limit for `FirstOrDefault()`: the query (including any `ORDER BY`) is wrapped in `ROWNUM <= 1` (limit written inline; NHibernate binds it as a parameter at runtime).
- `x.EndDate == null` becomes `IS NULL`. There is no `OrderBy`, so the row returned when several are active is not deterministic.
