# SQL-285: Retrieve RctPolicySelected

This NHibernate LINQ query reads `RCT_POLICY_SELECTED` and returns `RctPolicySelected` entities. `RctPolicySelectedService` uses an unfiltered query to retrieve all selected policies and a single-row lookup filtered by `PolicyNumber` to fetch or modify one policy.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-285 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `RctPolicySelectedService` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetRctPolicySelected()`, `GetRctPolicySelected(long)`, `ModifyRctPolicySelected` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:PolicyNumber` | Input | long | N/A | `policyNumber` (L43) / `policySelected.PolicyNumber` (L58) |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [RCT_POLICY_SELECTED](../database-tables.md#rct_policy_selected) | SELECT | `POLICY_NUM`, `POLICY_PERIOD_EFF_DATE`, `POLICY_STATUS_CODE`, `TRANSMITTED_DATE`, `CLIENT_UNIQUE_ID`, `CREATE_DATE`, `CREATE_USER`, `UPDATE_DATE`, `UPDATE_USER` |

## LINQ statement

Source: `Services/SAIF.Services/Rct/RctPolicySelectedService.cs:35-36`

```csharp
// Services/SAIF.Services/Rct/RctPolicySelectedService.cs:35-36
var dataPolicies = _unitOfWork.GetRepository<DataRct.RctPolicySelected>().Query();
var contractPolicies = Mapper.Map<RctPolicySelected[]>(dataPolicies);

// Services/SAIF.Services/Rct/RctPolicySelectedService.cs:43
var dataPolicy = _unitOfWork.GetRepository<DataRct.RctPolicySelected>().Query().SingleOrDefault(x => x.PolicyNumber == policyNumber);

// Services/SAIF.Services/Rct/RctPolicySelectedService.cs:58
var rctPolicySelected = _unitOfWork.GetRepository<DataRct.RctPolicySelected>().Query().SingleOrDefault(x => x.PolicyNumber == policySelected.PolicyNumber);
```

## 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
-- GetRctPolicySelected() (L35): enumerated by Mapper.Map at L36
SELECT
  RPS.POLICY_NUM,
  RPS.POLICY_PERIOD_EFF_DATE,
  RPS.POLICY_STATUS_CODE,
  RPS.TRANSMITTED_DATE,
  RPS.CLIENT_UNIQUE_ID,
  RPS.CREATE_DATE,
  RPS.CREATE_USER,
  RPS.UPDATE_DATE,
  RPS.UPDATE_USER
FROM RCT_POLICY_SELECTED RPS

-- GetRctPolicySelected(long) (L43) and ModifyRctPolicySelected (L58)
SELECT
  RPS.POLICY_NUM,
  RPS.POLICY_PERIOD_EFF_DATE,
  RPS.POLICY_STATUS_CODE,
  RPS.TRANSMITTED_DATE,
  RPS.CLIENT_UNIQUE_ID,
  RPS.CREATE_DATE,
  RPS.CREATE_USER,
  RPS.UPDATE_DATE,
  RPS.UPDATE_USER
FROM RCT_POLICY_SELECTED RPS
WHERE RPS.POLICY_NUM = :PolicyNumber
-- NHibernate expects at most one row
```

Translation notes:
- L35 builds an unexecuted `IQueryable`; `Mapper.Map<RctPolicySelected[]>` enumerates it (full-table read).
- `Single`/`SingleOrDefault` → no row limit; NHibernate throws if more than one row is returned.
