# SQL-004: Create BillOverride via Add

This ORM statement performs a create operation on `BillOverride` via `Add`, executed from `Services/SAIF.Services/Edi/BillOverrideService.cs` (L134).

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-004 |
| **Operation type** | Create |
| **Execution method** | ORM (IRepository.Add) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `BillOverride` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `Add` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:Id` | Input | `long?` | N/A | Identifier supplied by the caller |
| `:IsBypassed` | Input | `bool` | N/A | Bound as `'Y'`/`'N'` (`YesNoType`) |
| `:BillTypeCode` | Input | `string` | N/A |  |
| `:ClaimsBillsProcessingAdmissionTypeCode` | Input | `string` | N/A |  |
| `:DrugCode` | Input | `string` | N/A |  |
| `:OverrideText` | Input | `string` | N/A |  |
| `:StatementThruDate` | Input | `DateTime?` | N/A |  |
| `:UniformBillingBillTypeCode` | Input | `string` | N/A |  |
| `:UpdateDate` | Input | `DateTime?` | N/A |  |
| `:UpdateNumber` | Input | `long` | N/A |  |
| `:UpdateUser` | Input | `string` | N/A |  |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [EDI_BILL_OVERRIDE](../database-tables.md#edi_bill_override) | INSERT | BILL_ID, BYPASS_FLAG, BILL_TYPE_CODE, CBP_ADMISSION_TYPE_CODE, DRG_CODE, OVERRIDE_TEXT, STATEMENT_THRU_DATE, UB_BILL_TYPE_CODE, UPDATE_DATE, UPDATE_NUM, UPDATE_USER |

## LINQ statement

Source: `Services/SAIF.Services/Edi/BillOverrideService.cs:134`.

```csharp
// Services/SAIF.Services/Edi/BillOverrideService.cs:134
unitOfWork.GetRepository<DataModel.BillOverride>().Add(newBillOverride);
```

## 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
INSERT INTO EDI_BILL_OVERRIDE (
  BILL_ID,
  BYPASS_FLAG,
  BILL_TYPE_CODE,
  CBP_ADMISSION_TYPE_CODE,
  DRG_CODE,
  OVERRIDE_TEXT,
  STATEMENT_THRU_DATE,
  UB_BILL_TYPE_CODE,
  UPDATE_DATE,
  UPDATE_NUM,
  UPDATE_USER)
VALUES (
  :Id,
  :IsBypassed,
  :BillTypeCode,
  :ClaimsBillsProcessingAdmissionTypeCode,
  :DrugCode,
  :OverrideText,
  :StatementThruDate,
  :UniformBillingBillTypeCode,
  :UpdateDate,
  :UpdateNumber,
  :UpdateUser)
```

Translation notes:
- `GeneratedBy.Assigned()`: `:Id` is supplied by the caller. Because the identifier is assigned, a stateful `SaveOrUpdate` cannot tell a new instance from a detached one by identifier alone; NHibernate may first issue a `SELECT` by `BILL_ID` (or rely on the version unsaved-value, if mapped) to decide between INSERT and UPDATE.
- `:IsBypassed` are bound as `'Y'` / `'N'` (`YesNoType`).
