# SQL-197: PolicyQueryProvider.GetBusiness

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-197 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `PolicyQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetBusiness` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `policyNumber` | Input | long | N/A | Method argument of `PolicyQueryProvider.GetBusiness` bound into the ORM expression; NHibernate generates the bind variable at runtime |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [BUSINESS](../database-tables.md#business) | SELECT | POLICY_NUM, BUS_SEQ_NUM, BUS_EFF_DATE, BUS_EXP_DATE, FEID_NUM, PRIMARY_BUS_FLAG |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Policies/PolicyQueryProvider.cs:44-45`.

```csharp
public Business GetBusiness(long policyNumber)
{
    return Factory.GetRepository<Business>().Query()
        .SingleOrDefault((x => x.PolicyNumber == policyNumber && x.IsPrimaryBusiness));
}
```

## 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
  B.POLICY_NUM,
  B.BUS_SEQ_NUM,
  B.BUS_EFF_DATE,
  B.BUS_EXP_DATE,
  B.FEID_NUM,
  B.PRIMARY_BUS_FLAG
FROM BUSINESS B
WHERE B.POLICY_NUM = :policyNumber
  AND B.PRIMARY_BUS_FLAG = 'Y'
-- SingleOrDefault: NHibernate expects at most one row
```

Translation notes:
- `IsPrimaryBusiness` → `PRIMARY_BUS_FLAG`, `CustomType<YesNoType>()` (`BusinessMap.cs:20`) → `'Y'`.
