# SQL-148: ImageQueryProvider.GetAffilliatedImages

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-148 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | Unknown** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `ImageQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetAffilliatedImages` |


## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:imageIds` | Input | List<long> | N/A | Built in memory: `imageId` plus each `AffiliationImageId` from the loaded affiliations. `Contains` becomes `IN`, and NHibernate expands the list into one bind per element |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| `image**` | SELECT | unresolved (see Unresolved mapping) |
| [IMAGE_AFFILIATION](../database-tables.md#image_affiliation)** | SELECT (lazy collection load, step 2; separate statement) | unresolved (see Unresolved mapping) |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:27`. The repository is obtained at `Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:15`.

```csharp
// Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:15
repository = Factory.GetRepository<Image>().Query();

// Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:25
var imageIds = new List<long> { imageId };
imageIds.AddRange(GetImage(imageId).ImageAffiliations.Select(item => item.AffiliationImageId));
return repository.Where(x => imageIds.Contains(x.Id)).ToList();
```

## 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
-- Step 1 (L26): GetImage(imageId) runs SQL-147.
-- Step 2 (L26): lazy load of Image.ImageAffiliations (HasMany IMAGE_AFFILIATION); columns unresolved, so not written.
-- Step 3 (L27): the statement documented here
SELECT
  <all mapped columns of Image> -- unresolved mapping: Image column list not documented
FROM image I
WHERE I.<Id column> IN (:imageIds) -- unresolved mapping: Image.Id
```

Translation notes:
- There are three round trips in total: SQL-147, the lazy collection initialization, then the `IN` query.
- With a large affiliation list, Oracle's 1000-element `IN` limit could be reached. NHibernate does not split the list automatically.
