# SQL-026: GroupRepository.GroupFound

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-026 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `GroupRepository` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GroupFound` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:groupId` | Input | string | N/A | Method argument bound into the LINQ expression |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [group_association](../database-tables.md#group_association) | SELECT | `code`, `code_descr`, `phone`, `code_acronym`, `association_exp_date`, `group_representative`, `group_type_code`, `parent_group` |

## LINQ statement

Source: `Data/SAIF.Data.NHibernate/Repositories/Groups/GroupRepository.cs:21`.

```csharp
public bool GroupFound(string groupId)
{
    var group = GetGroupOrDefault(groupId);
    return group != null;
}

public GroupAssociation GetGroupOrDefault(string groupId)
{
    return Query().SingleOrDefault(g => g.Id == groupId);
}
```

## 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
  GA.code,
  GA.code_descr,
  GA.phone,
  GA.code_acronym,
  GA.association_exp_date,
  GA.group_representative,
  GA.group_type_code,
  GA.parent_group
FROM group_association GA
WHERE GA.code = :groupId
-- NHibernate expects at most one row
```

Translation notes:
- Same database statement as SQL-027 (`GroupFound` delegates to `GetGroupOrDefault`). `group != null` is evaluated in memory. `Query()` is `RepositoryBase<TEntity>.Query()` → `Session.Query<TEntity>()` (`SAIF.Framework.Data.NHibernate` `RepositoryBase<T>`, package decompile).
- `GroupAssociation.Type`, `.SAIFRepresentative`, and `.ParentGroup` are lazy `References`; only their FK columns (`group_type_code`, `group_representative`, `parent_group`) are selected. `ChildGroups` is a lazy `HasMany` and is not selected.
