# SQL-239: Retrieve OtherStatesPolicy via GetOscPolicyById

This ORM statement retrieves a single `OtherStatesPolicy` (an other-states-coverage policy) by its primary key, via `IUnitOfWork.GetRepository<T>()`, executed from `Services/SAIF.Services/Policies/Certificates/Information/CertificateInformationDataHelper.cs (L39)`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-239 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `CertificateInformationDataHelper` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetOscPolicyById` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:oscPolicyId` | Input | long | N/A | Primary key of the `OtherStatesPolicy` to retrieve |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [OSC_POLICY_VIEW](../database-tables.md#osc_policy_view) | SELECT | `OSC_POLICY_SEQ_NUM`, `OSC_LEGAL_NAME`, `OSC_POLICY_NUM`, `cancel_date`, `POLICY_STATUS_CODE`, `POLICY_NUM`, `AGENT_NUM` |

## LINQ statement

Source: `Services/SAIF.Services/Policies/Certificates/Information/CertificateInformationDataHelper.cs:39`

```csharp
// Services/SAIF.Services/Policies/Certificates/Information/CertificateInformationDataHelper.cs:39-40
return unitOfWork.GetRepository<OtherStatesPolicy>()
    .Query().Single(p => p.Id == oscPolicyId);
```

## 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
  OPV.OSC_POLICY_SEQ_NUM,
  OPV.OSC_LEGAL_NAME,
  OPV.OSC_POLICY_NUM,
  OPV.cancel_date,
  OPV.POLICY_STATUS_CODE,
  OPV.POLICY_NUM,
  OPV.AGENT_NUM
FROM OSC_POLICY_VIEW OPV
WHERE OPV.OSC_POLICY_SEQ_NUM = :oscPolicyId
-- NHibernate expects at most one row
```

Translation notes:
- `Single(...)` throws when no row or more than one row is returned; no row limit is applied.
- `HasMany(Periods)` is lazy and not selected.
