# SQL-285: PolicyExtensions.GenerateRelationshipPolicies

This statement is a read operation invoked through ORM (NHibernate LINQ). Executed by `PolicyExtensions.GenerateRelationshipPolicies`.

## 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** | `PolicyExtensions` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GenerateRelationshipPolicies` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `relationship` | Input | string | N/A | Method argument of `PolicyExtensions.GenerateRelationshipPolicies` bound into the ORM expression; NHibernate generates the bind variable at runtime |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [POLICY_RELATIONSHIP_CODE](../database-tables.md#policy_relationship_code) | SELECT ×1 (hypothetical) | CODE, CODE_DESCR |

## LINQ statement

Source: `Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:133`.

```csharp
// Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:133
var rel = uow.GetRepository<PolicyRelationshipCode>().Query().SingleOrDefault(x => x.Code == relationship.ToUpper());
```

## Sample SQL

> **Test double — no runtime SQL.** This statement executes against `TestUnitOfWork`/`TestRepository<T>` (in-memory, `List<TEntity>`-backed test doubles in `SAIF.Framework.Core`); no NHibernate session is opened and no SQL is issued at runtime. The SQL below is the hypothetical statement the same expression would produce against a real NHibernate `IUnitOfWork` using the in-repo mappings, shown to document the mapping shape only — **no database table is accessed when this code runs.**

> **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
-- line 133
SELECT
  PRC.CODE,
  PRC.CODE_DESCR
FROM POLICY_RELATIONSHIP_CODE PRC
WHERE PRC.CODE = :p0
-- SingleOrDefault
```

Translation notes:
- String constants (and captured values) are bound as parameters by NHibernate (`:p0`); the literal is shown in the trailing comment.
- `relationship.ToUpper()` does not depend on the lambda parameter; it is evaluated in memory and bound as `:p0`.
