# SQL-078: EbillBatchQueryProvider.GetBatch

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-078 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `EbillBatchQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetBatch` |

## Parameters

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

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [EBILL_BATCH](../database-tables.md#ebill_batch) | SELECT | `EBILL_BATCH_SEQ_NUM`, `UPDATE_NUM`, `CREATE_DATE`, `SUBMISSION_DATE`, `UPDATE_DATE`, `UPDATE_USER`, `CLEARINGHOUSE_FILE_NAME`, `EBILL_BATCH_TYPE_CODE`, `RESPONSE_BATCH_SEQ_NUM`, `EBILL_BATCH_STATUS_CODE`, `PAYMENT_TRANS_STAT_SEQ_NUM`, `EBILL_CLEARINGHOUSE_SEQ_NUM` |

```csharp
// Data/SAIF.Data/Queries/Claims/Ebilling/EbillBatchQueryProvider.cs:19
batchRepository = Factory.GetRepository<EbillBatch>().Query();

// Data/SAIF.Data/Queries/Claims/Ebilling/EbillBatchQueryProvider.cs:26
return batchRepository.SingleOrDefault(b => b.Id == batchId);
```

## 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
  EB.EBILL_BATCH_SEQ_NUM,
  EB.UPDATE_NUM,
  EB.CREATE_DATE,
  EB.SUBMISSION_DATE,
  EB.UPDATE_DATE,
  EB.UPDATE_USER,
  EB.CLEARINGHOUSE_FILE_NAME,
  EB.EBILL_BATCH_TYPE_CODE,
  EB.RESPONSE_BATCH_SEQ_NUM,
  EB.EBILL_BATCH_STATUS_CODE,
  EB.PAYMENT_TRANS_STAT_SEQ_NUM,
  EB.EBILL_CLEARINGHOUSE_SEQ_NUM
FROM EBILL_BATCH EB
WHERE EB.EBILL_BATCH_SEQ_NUM = :batchId
-- NHibernate expects at most one row
```

Translation notes:

- Direct translation: an equality predicate on mapped columns. No navigation, joins or in-memory operators.
