# SQL-275: OnlineSupportExtensions.SeedForOnlineSupport

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-275 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | SQL Server* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `OnlineSupportExtensions` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `SeedForOnlineSupport` |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [ERROR_ENVIRONMENT](../database-tables.md#error_environment) | INSERT ×27, SELECT (hypothetical) | ID, ENVIRONMENT_NAME, DESCRIPTION |

## LINQ statement

Source: `Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:60`.

```csharp
// Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:60-61
var environments = unitOfWork.GetRepository<ErrorEnvironment>();
CreateEnvironments(environments);

// Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:116-150
private static void CreateEnvironments(IRepository<ErrorEnvironment> repo)
{
    repo.Add(new ErrorEnvironment { Id = 1, EnvironmentName = "entdev01", Description = "entdev01" });
    repo.Add(new ErrorEnvironment { Id = 2, EnvironmentName = "entdev03", Description = "entdev03" });
    // ... 25 further Add/AddCode call(s) through line 150 (elided)
}

// Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:79
var envs = environments.Query().ToList();
```

## 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_ENVIRONMENT (
  ID,
  ENVIRONMENT_NAME,
  DESCRIPTION)
VALUES (
  @Id,
  @EnvironmentName,
  @Description)
-- issued 27 time(s), CreateEnvironments lines 116-150

-- line 79: environments.Query().ToList()
SELECT
  EE.ID,
  EE.ENVIRONMENT_NAME,
  EE.DESCRIPTION
FROM ERROR_ENVIRONMENT EE
```

Translation notes:
- Several rows reuse the same assigned `Id` (e.g. 14 ×4, 1-9 twice); against a real database these INSERTs would violate the primary key — only the in-memory double tolerates them.
