```csharp
// Data/SAIF.Data/TestRepository/RepositoryExtensions/EbillingExtensions.cs:20
uow.GetRepository<EbillBatchTypeCode>().Seed();

// Data/SAIF.Data/TestRepository/RepositoryExtensions/EbillingExtensions.cs:39-55
public static void Seed(this IRepository<EbillBatchTypeCode> repository)
{

    //select * from ebill_batch_type_code;

    //select 'repository.Add(new EbillBatchTypeCode { Code = "' || code || 
    //    '", Description = "' || code_descr || '", ManualVersion = "' || manual_version_num || 
    //    '", FunctionalGroupCode = "' || functional_group_code || '"});' as code
    //    from ebill_batch_type_code;

    repository.Add(new EbillBatchTypeCode { Code = "837", Description = "Ebill", ManualVersion = "", FunctionalGroupCode = "HC" });
    repository.Add(new EbillBatchTypeCode { Code = "835", Description = "Ebill payment advice", ManualVersion = "005010X221A1", FunctionalGroupCode = "HP" });
    repository.Add(new EbillBatchTypeCode { Code = "277CA", Description = "Ebill status response", ManualVersion = "005010X214", FunctionalGroupCode = "HN" });
    // ... 2 further Add/AddCode call(s) through line 55 (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 EBILL_BATCH_TYPE_CODE (
  CODE,
  UPDATE_NUM,
  CODE_DESCR,
  UPDATE_USER,
  UPDATE_DATE,
  FUNCTIONAL_GROUP_CODE,
  MANUAL_VERSION_NUM,
  EBILL_BATCH_SOURCE_CODE)
VALUES (
  :Code,
  :UpdateNumber,
  :Description,
  :UpdateUser,
  :UpdateDate,
  :FunctionalGroupCode,
  :ManualVersion,
  :SourceCode)
-- issued 5 time(s) (one per repository.Add, lines 39-55)
```

Translation notes:
- Rows are added directly with `repository.Add(new T {...})` (no existence probe).
