# SQL-235: TaskQueryProvider.GetTask

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-235 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `TaskQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetTask` |

## Parameters

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

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [TASK](../database-tables.md#task) | SELECT | TASK_SEQ_NUM, UPDATE_SEQ_NUM, TASK_DATE, TASK_TEXT, TASK_USER, NOTEPAD_FLAG, DELETE_FLAG, IMAGE_SEQ_NUM, CONTEXT_CODE, CONTEXT_KEY, CONTEXT_CATEGORY, CONTEXT_TEXT, CONTEXT_DATE, CONTEXT_NUM, CREATE_DATE, CREATE_USER, UPDATE_DATE, UPDATE_USER, TASK_SECURITY, CLAIM_ID, POLICY_NUM, TASK_ACTION_CODE, TASK_CATEGORY_CODE, TASK_PRIORITY_CODE, TASK_SOURCE_CODE, CLAIM_TASK_GROUP_CODE, LEGAL_NOTE_CATEGORY_CODE |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Tasks/TaskQueryProvider.cs:53`.

```csharp
// Data/SAIF.Data/Queries/Tasks/TaskQueryProvider.cs:22
tasks = factory.GetRepository<Task>();

// Data/SAIF.Data/Queries/Tasks/TaskQueryProvider.cs:53
return tasks.Query().SingleOrDefault(x => x.Id == taskId);
```

## 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
  T.TASK_SEQ_NUM,
  T.UPDATE_SEQ_NUM,
  T.TASK_DATE,
  T.TASK_TEXT,
  T.TASK_USER,
  T.NOTEPAD_FLAG,
  T.DELETE_FLAG,
  T.IMAGE_SEQ_NUM,
  T.CONTEXT_CODE,
  T.CONTEXT_KEY,
  T.CONTEXT_CATEGORY,
  T.CONTEXT_TEXT,
  T.CONTEXT_DATE,
  T.CONTEXT_NUM,
  T.CREATE_DATE,
  T.CREATE_USER,
  T.UPDATE_DATE,
  T.UPDATE_USER,
  T.TASK_SECURITY,
  T.CLAIM_ID,
  T.POLICY_NUM,
  T.TASK_ACTION_CODE,
  T.TASK_CATEGORY_CODE,
  T.TASK_PRIORITY_CODE,
  T.TASK_SOURCE_CODE,
  T.CLAIM_TASK_GROUP_CODE,
  T.LEGAL_NOTE_CATEGORY_CODE
FROM TASK T
WHERE T.TASK_SEQ_NUM = :taskId
-- SingleOrDefault
```

Translation notes:
- Not accessed: None. The seven `References(...)` on `TaskMap` (policy, action, category, priority, source, claim task group, legal note category) contribute FK columns only; no join is emitted.
- The repository is the class field `tasks` initialised at line 22 from `Factory.GetRepository<Task>()`.
