# SQL-024 Retrieve case status codes by prior status

Retrieves `CASE_STATUS_CODE` rows matching one or two prior status codes taken from the case's status history, for the `clsUpdateCaseManager.CaseStatusList` property used by the update-case status maintenance UI. The executable SQL is assembled at runtime from two constants — `CASESTATUSCODESQL` (opening clause, ending at `WHERE code in ('`) and `ORDERSQL` (closing clause, `') `) — with one or two status codes concatenated between them.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-024 |
| **Operation type** | Read |
| **Execution method** | Inline SQL, runtime string concatenation (`clsCodeCollection.GetCodeCollection`) |
| **Database** | Oracle |
| **Command type** | Text |
| **Business object** | N/A (Application layer) |
| **Criteria property** | N/A (Application layer) |
| **Lifecycle method** | N/A (Application layer) |
| **Application class** | `clsUpdateCaseManager` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `CurrentCase.StatusHistory(0).StatusCode`, `CurrentCase.StatusHistory(1).StatusCode` | N/A — concatenated literals, not bind parameters* | String | N/A | One or two prior case-status codes concatenated directly into the `IN` list text of `CASESTATUSCODESQL` (see Sample SQL below) rather than bound as Oracle parameters*. |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [CASE_STATUS_CODE](../database-tables.md#case_status_code) | SELECT | `CODE`, `CODE_DESCR` |

## Sample SQL

```sql
SELECT code, code_descr
FROM CASE_STATUS_CODE
WHERE code in ('<StatusCode0>', '<StatusCode1>')
```

The constant `CASESTATUSCODESQL` ends at `WHERE code in ('`, and the constant `ORDERSQL` supplies the closing `') `. At runtime, `clsUpdateCaseManager.CaseStatusList` concatenates one or two `CurrentCase.StatusHistory(n).StatusCode` values between them (`CASESTATUSCODESQL + StatusCode0 + "', '" + StatusCode1 + ORDERSQL`, or `CASESTATUSCODESQL + StatusCode0 + ORDERSQL` when only one prior status exists) — the reconstructed executable text above reflects the two-status case; values are concatenated directly into the SQL text, not bound as Oracle parameters*.
