# SQL-190: Retrieve EmployerLiabilityLimit via GetSpecificLimit

This statement retrieves a single `EmployerLiabilityLimit` record by its code, called from `CertificateInformationDataHelper.GetSpecificLimit`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-190 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `CertificateInformationDataHelper` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetSpecificLimit` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:limitCode` | Input | String | N/A | `limitCode` — filters `EMP_LIAB_STAT_CODE` |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [EMPLOYERS_LIABILITY_LIMITS](../database-tables.md#employers_liability_limits) | SELECT | `EMP_LIAB_STAT_CODE`, `EMP_LIAB_LIMIT1`, `EMP_LIAB_LIMIT2`, `EMP_LIAB_LIMIT3`, `STANDARD_LIMITS_FLAG`; filter `EMP_LIAB_STAT_CODE` |

## LINQ statement

Source: `Services/SAIF.Services/Policies/Certificates/Information/CertificateInformationDataHelper.cs:26`

```csharp
return unitOfWork.GetRepository<EmployerLiabilityLimit>()
    .Query().SingleOrDefault(lim => lim.Code == limitCode);
```

## 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 ELL.EMP_LIAB_STAT_CODE,
       ELL.EMP_LIAB_LIMIT1,
       ELL.EMP_LIAB_LIMIT2,
       ELL.EMP_LIAB_LIMIT3,
       ELL.STANDARD_LIMITS_FLAG
FROM   Employers_Liability_Limits ELL
WHERE  ELL.EMP_LIAB_STAT_CODE = :limitCode
-- NHibernate expects at most one row
```

Translation notes:
- `SingleOrDefault`/`Single` add no row limit; NHibernate throws if more than one row is returned.
