# SQL-072: Retrieve AdjustmentReason via SaveBillServices

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |

## LINQ statement

Source: `Services/SAIF.Services/Legal/Bills/BillSaveService.cs:444-448`.

```csharp
// Services/SAIF.Services/Legal/Bills/BillSaveService.cs:444
billService.AdjustmentReason = legalBillService.AdjustmentReason == null
    ? null
    : _unitOfWork.GetRepository<BillData.AdjustmentReason>()
      .Query()
      .SingleOrDefault(x => x.Code == legalBillService.AdjustmentReason.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
SELECT
  ARC.CODE,
  ARC.CODE_DESCR,
  ARC.CODE_LONG_DESCR,
  ARC.MAIL_MERGE_TEXT
FROM ADJUSTMENT_REASON_CODE ARC
WHERE ARC.CODE = :Code
-- NHibernate expects at most one row
```

Translation notes:
- The query executes only when `legalBillService.AdjustmentReason != null` (C# conditional at line 444); otherwise no SQL is issued.
- `Code` / `Description` are inherited from `CodeTableEntity<AdjustmentReason>`; the map declares `Id(x => x.Code).Column("CODE")`.
- The neighbouring `BillService` and `BillServiceRateType` lookups (lines 438-443) are separate statements, not part of this SQL ID.

## Operations and processes
