| **Database** | SQL Server* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `OnlineSupportExtensions` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `SeedForOnlineSupport` |

## LINQ statement

Source: `Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:56`.

```csharp
// Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:56-58
var groupRepo = unitOfWork.GetRepository<ErrorGroupCode>();
CreateEnvironmentGroups(groupRepo);
var groups = groupRepo.Query().ToList();

// Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:152-165
private static void CreateEnvironmentGroups(IRepository<ErrorGroupCode> repo)
{
    repo.Add(new ErrorGroupCode { Code = "D", Description = "Dev" });
    repo.Add(new ErrorGroupCode { Code = "T", Description = "Test" });
    // ... 8 further Add/AddCode call(s) through line 165 (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 ERROR_GROUP_CODE (
  CODE,
  DESCRIPTION)
VALUES (
  @Code,
  @Description)
-- issued 10 time(s), CreateEnvironmentGroups lines 152-165

-- line 58: groupRepo.Query().ToList()
SELECT
  EGC.CODE,
  EGC.DESCRIPTION
FROM ERROR_GROUP_CODE EGC
```

Translation notes:
- The subsequent `groups.SingleOrDefault(...)` calls (lines 63-71) run on the in-memory list, not the database.
