## LINQ statement

Source: `Services/SAIF.Services/Legal/Bills/BillPaymentService.cs:382`

```csharp
// Services/SAIF.Services/Legal/Bills/BillPaymentService.cs:382-384
            bill.BillStatus = _unitOfWork.GetRepository<BillData.BillStatus>()
                .Query()
                .SingleOrDefault(x => x.Code == toCode);
```

## 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/BillPaymentService.cs:382
SELECT
  BSC.CODE,
  BSC.CODE_DESCR,
  BSC.FILTER_GROUPING_TEXT
FROM BILL_STATUS_CODE BSC
WHERE BSC.CODE = :toCode
-- NHibernate expects at most one row
```
