# SQL-201: Retrieve HearingLocation via SetSubpoenaData

This statement loads a single `HearingLocation` record by its identifier so that `SubpoenaSaveService.SetSubpoenaData` can assign the hearing location on a subpoena. It is issued through NHibernate LINQ against the `HearingLocation` entity from `Services/SAIF.Services/Legal/Subpoenas/SubpoenaSaveService.cs:151`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-201 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `SubpoenaSaveService` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `SetSubpoenaData` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:hearingLocationId` | Input | long | N/A | `subpoena.HearingLocation.Id`, captured contract value |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [HEARING_LOCATION](../database-tables.md#hearing_location) | SELECT | HEARING_LOCATION_SEQ_NUM, LOCATION_NAME, ADDR1, ADDR2, ADDR3, CITY, STATE, ZIP, ZIP4, EFF_DATE, EXP_DATE, CREATE_USER, CREATE_DATE, UPDATE_USER, UPDATE_DATE, HEARING_LOCATION_CODE |

## LINQ statement

Source: `Services/SAIF.Services/Legal/Subpoenas/SubpoenaSaveService.cs:151`

```csharp
dataSubpoena.HearingLocation =
    _unitOfWork.GetRepository<LegalData.HearingLocation>()
        .Query().SingleOrDefault(x => x.Id == subpoena.HearingLocation.Id);
```

## 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 HL.HEARING_LOCATION_SEQ_NUM,
       HL.LOCATION_NAME,
       HL.ADDR1,
       HL.ADDR2,
       HL.ADDR3,
       HL.CITY,
       HL.STATE,
       HL.ZIP,
       HL.ZIP4,
       HL.EFF_DATE,
       HL.EXP_DATE,
       HL.CREATE_USER,
       HL.CREATE_DATE,
       HL.UPDATE_USER,
       HL.UPDATE_DATE,
       HL.HEARING_LOCATION_CODE
FROM   HEARING_LOCATION HL
WHERE  HL.HEARING_LOCATION_SEQ_NUM = :hearingLocationId;
-- NHibernate expects at most one row
```

Translation notes:
- `SingleOrDefault`/`Single` add no row limit; NHibernate throws if more than one row is returned.
