## LINQ statement

Source: `Services/SAIF.Services/Legal/Bills/BillSaveService.cs:349`

```csharp
// Services/SAIF.Services/Legal/Bills/BillSaveService.cs:349-352
                legalBill.BillStatus =
                       _unitOfWork.GetRepository<BillData.BillStatus>()
                           .Query()
                           .SingleOrDefault(x => x.Code == bill.BillStatus.Code);

// Services/SAIF.Services/Legal/Bills/BillSaveService.cs:367-370
                    legalBill.BillStatus =
                              _unitOfWork.GetRepository<BillData.BillStatus>()
                             .Query()
                              .SingleOrDefault(x => x.Code == bill.BillStatus.Code);
```

## 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
-- Services/SAIF.Services/Legal/Bills/BillSaveService.cs:350
SELECT
  BSC.CODE,
  BSC.CODE_DESCR,
  BSC.FILTER_GROUPING_TEXT
FROM BILL_STATUS_CODE BSC
WHERE BSC.CODE = :Code
-- NHibernate expects at most one row

-- Services/SAIF.Services/Legal/Bills/BillSaveService.cs:368
SELECT
  BSC.CODE,
  BSC.CODE_DESCR,
  BSC.FILTER_GROUPING_TEXT
FROM BILL_STATUS_CODE BSC
WHERE BSC.CODE = :Code
-- NHibernate expects at most one row
```

Translation notes:
- `bill.BillStatus.Code` is a member of the in-memory contract object -> bind `:Code` (evaluated client-side).
