# SQL-254: TaskExtensions.FillTaskCategory

This statement is a create operation invoked through ORM (IRepository.Add). Executed by `TaskExtensions.FillTaskCategory`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-254 |
| **Operation type** | Create |
| **Execution method** | ORM (IRepository.Add) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `TaskExtensions` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `FillTaskCategory` |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [TASK_CATEGORY_CODE](../database-tables.md#task_category_code) | INSERT ×6 (hypothetical) | Code, CODE_DESCR, NOTEPAD_REQUIRED_FLAG, DEFAULT_ACTION_CODE, DEFAULT_PRIORITY_CODE, TASK_SOURCE_CODE |

## LINQ statement

Source: `Data/SAIF.Data/TestRepository/RepositoryExtensions/TaskExtensions.cs:47`.

```csharp
// Data/SAIF.Data/TestRepository/RepositoryExtensions/TaskExtensions.cs:45-110
private static void FillTaskCategory(IUnitOfWork uow)
{
    var repo = uow.GetRepository<TaskCategory>();
    var med = uow.GetRepository<TaskPriority>().Query().SingleOrDefault(x => x.Code == "MED");
    var info = uow.GetRepository<TaskPriority>().Query().SingleOrDefault(x => x.Code == "INFO");
    var act = uow.GetRepository<TaskAction>().Query().SingleOrDefault(x => x.Code == "NONE");
    var image = uow.GetRepository<TaskSource>().Query().SingleOrDefault(x => x.Code == "IMAGE");
    var wcis = uow.GetRepository<TaskSource>().Query().SingleOrDefault(x => x.Code == "WCIS");

    repo.Add(new TaskCategory
    // ... 5 further Add/AddCode call(s) through line 110 (elided)
}
```

## 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
INSERT INTO TASK_CATEGORY_CODE (
  Code,
  CODE_DESCR,
  NOTEPAD_REQUIRED_FLAG,
  DEFAULT_ACTION_CODE,
  DEFAULT_PRIORITY_CODE,
  TASK_SOURCE_CODE)
VALUES (
  :Code,
  :Description,
  :IsNotepadRequired,
  :DefaultAction,
  :DefaultPriority,
  :TaskSource)
-- issued 6 time(s), lines 54-110
```

Translation notes:
- Not accessed: `TASK_PRIORITY_CODE`, `TASK_ACTION_CODE`, `TASK_SOURCE_CODE` — the lookups at lines 48-52 are separate statements (SQL-305/306/307); in the INSERT they contribute FK values only.
- `Id(Code)` column is literally `Code`. `NOTEPAD_REQUIRED_FLAG` is `YesNoType`.
