# SQL-133: Retrieve CbpServiceCode via ValidCptCode

This ORM statement performs a read operation on `CbpServiceCode` via `IUnitOfWork.GetRepository<T>()`, executed from `Services/SAIF.Services/Claims/Bills/AuthorizationService.cs (L75)`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-133 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `CbpServiceCode` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `ValidCptCode` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `code` | Input | ** | N/A | `x.Code == code` → column ** |
| `"M"` | Input | ** | N/A | `x.ServiceType.Code == "M"` → column ** |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [CBP_SERVICE_CODE](../database-tables.md#cbp_service_code) | SELECT | `CODE`, `BILL_SERVICE_TYPE_CODE`, `UPDATE_NUM`, `EFF_DATE`, `EXP_DATE`, `RP_1099_REQ_FLAG`, `UPDATE_USER`, `UPDATE_DATE`, `NURSE_REVIEW_REQUIRED_FLAG`, `DCBS_REPORT_SERVICE_CODE` |

## LINQ statement

Source: `Services/SAIF.Services/Claims/Bills/AuthorizationService.cs:75`

```csharp
// Services/SAIF.Services/Claims/Bills/AuthorizationService.cs:75
                unitOfWork.GetRepository<CbpServiceCode>().Query().Single(x => x.Code == code && x.ServiceType.Code == "M");
```

## 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
-- Services/SAIF.Services/Claims/Bills/AuthorizationService.cs:75
SELECT
  CSC.CODE,
  CSC.BILL_SERVICE_TYPE_CODE,
  CSC.UPDATE_NUM,
  CSC.EFF_DATE,
  CSC.EXP_DATE,
  CSC.RP_1099_REQ_FLAG,
  CSC.UPDATE_USER,
  CSC.UPDATE_DATE,
  CSC.NURSE_REVIEW_REQUIRED_FLAG,
  CSC.DCBS_REPORT_SERVICE_CODE
FROM CBP_SERVICE_CODE CSC
WHERE CSC.CODE = :code
  AND CSC.BILL_SERVICE_TYPE_CODE = 'M'
-- NHibernate expects at most one row
```
