# SQL-286: Retrieve RctPolicyServicePlan via ProcessOneServicePlan

This NHibernate LINQ query reads `LC_POLICY_SERVICE_PLAN` filtered by policy number and finds the currently-active service plan row (one whose expiration date is null or the NHibernate default-date sentinel). `RctServicePlanService.ProcessOneServicePlan` uses the first matching row returned by the Oracle10 row-limit wrapper.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-286 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `RctServicePlanService` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `ProcessOneServicePlan` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:PolicyNumber` | Input | long | N/A | `servicePlanChange.PolicyNumber` |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [LC_POLICY_SERVICE_PLAN](../database-tables.md#lc_policy_service_plan) | SELECT | `POLICY_NUM`, `EFF_DATE`, `EXP_DATE`, `LC_SERVICE_PLAN_CODE`, `CREATE_USER`, `CREATED_DATE`, `UPDATE_USER`, `UPDATE_DATE` |

## LINQ statement

Source: `Services/SAIF.Services/Rct/RctServicePlanService.cs:160-162`

```csharp
// Services/SAIF.Services/Rct/RctServicePlanService.cs:160-162
var servicePlans = _unitOfWork.GetRepository<Model.Rct.RctPolicyServicePlan>().Query();
var activeServicePlan = servicePlans.FirstOrDefault(x => x.PolicyNumber == servicePlanChange.PolicyNumber
    && (x.ExpirationDate == null || x.ExpirationDate == DateTime.MinValue));
```

## 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 *
FROM (
  SELECT
    LPSP.POLICY_NUM,
    LPSP.EFF_DATE,
    LPSP.EXP_DATE,
    LPSP.LC_SERVICE_PLAN_CODE,
    LPSP.CREATE_USER,
    LPSP.CREATED_DATE,
    LPSP.UPDATE_USER,
    LPSP.UPDATE_DATE
  FROM LC_POLICY_SERVICE_PLAN LPSP
  WHERE LPSP.POLICY_NUM = :PolicyNumber
    AND (LPSP.EXP_DATE IS NULL
      OR LPSP.EXP_DATE = TO_DATE('0001-01-01', 'YYYY-MM-DD'))
)
WHERE ROWNUM <= 1
```

Translation notes:
- L160 builds the `IQueryable`; the statement executes at `FirstOrDefault` (L161).
- `DateTime.MinValue` inlined as `0001-01-01`.
- `First`/`FirstOrDefault` → Oracle10 dialect row limit `SELECT * FROM (...) WHERE ROWNUM <= 1` (no `ORDER BY`, so the row returned is not deterministic if more than one matches).
