## 1. Role

### JBSbatKKAdChgFmtcelSodUpd.executeKK_T_PRG_KK_SELECT_025()

This method performs a **database SELECT query against the progress management table `KK_T_PRG`** to retrieve records associated with a service contract change formatting cell order update process. Specifically, it searches the progress table using four bind variables — service contract number, status change classification (idoun kibun), progress status, and progress year/month/day/hour/minute/second — to locate the current processing state of a cel (format) change order.

The method is a **private data access helper** that encapsulates a single SQL query invocation using the SQL define key `KK_SELECT_025`. It follows a consistent pattern across the batch service class: accept an `Object[]` parameter array, populate a `JBSbatCommonDBInterface` bind variable list, and delegate to the `JBSbatSQLAccess` abstraction for the actual database call. This method does not contain conditional branches or business logic routing; it is a pure read operation that returns results through the `paramList` object (passed by reference), which will be populated with query result rows for the caller to process.

In the larger system, this method supports the **Address Change Format Cell Order Update** batch process. The progress table (`KK_T_PRG`) tracks the execution state of batch jobs, and this query allows the batch to check or update its own processing progress markers. It is called from the main `execute()` method of the same class, as part of the batch processing workflow.

    START(["executeKK_T_PRG_KK_SELECT_025(Object[] param)"])

    START --> STEP1["Step 1: Generate bind variable list"]
    STEP1 --> NEW["paramList = new JBSbatCommonDBInterface()"]
    NEW --> SET0["paramList.setValue(param[0].toString())"]
    SET0 --> SET1["paramList.setValue(param[1].toString())"]

    SET3 --> EXEC["db_KK_T_PRG.selectBySqlDefine(paramList, KK_T_PRG_KK_SELECT_025)"]

    SET0 -.-> KEY["KK_SELECT_025 (SQL Key)"]
    EXEC -.-> TABLE["KK_T_PRG (Progress Table)"]
```

**Processing Description:**

1. **Bind Variable List Generation** — A new `JBSbatCommonDBInterface` object (`paramList`) is instantiated to hold the SQL bind variables for the query.
2. **Bind Variable Assignment** — Four values from the `param` array are extracted via `toString()` and set as sequential bind variables on `paramList`:
   - `param[0]`: Service contract number (サービス契約番号)
   - `param[1]`: Status change classification (異動区分)
   - `param[2]`: Progress status (進捗ステータス)
   - `param[3]`: Progress date/time (進捗年月日時分秒)
3. **Database Access Execution** — The `selectBySqlDefine` method is invoked on the `db_KK_T_PRG` SQL access instance, passing the populated bind variable list and the SQL define key `KK_T_PRG_KK_SELECT_025` (value: `"KK_SELECT_025"`). The query results are populated back into `paramList` for the caller to consume.

**Constant Resolution:**

| Constant | Value | Business Meaning |
|----------|-------|-----------------|
| `KK_T_PRG_KK_SELECT_025` | `"KK_SELECT_025"` | SQL define key for selecting records from the progress table `KK_T_PRG` |
| `D_TBL_NAME_KK_T_PRG` | `"KK_T_PRG"` | Database table name for progress management (進捗) |

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | `Object[]` | An array of 4 bind variable values for the SQL query. Elements are: (0) Service contract number — the unique identifier for a service contract line item; (1) Status change classification (idoun kibun) — the type of status transition being tracked (e.g., initiation, completion, error); (2) Progress status — the current processing state code; (3) Progress date/time — a timestamp representing when the current progress state was recorded, formatted as year/month/day/hour/minute/second. |

**Instance fields read by this method:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `db_KK_T_PRG` | `JBSbatSQLAccess` | SQL access abstraction layer for the `KK_T_PRG` (progress) table. Initialized elsewhere in the class lifecycle and provides the `selectBySqlDefine` database query method. |

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `db_KK_T_PRG.selectBySqlDefine` | — | `KK_T_PRG` | Selects records from the progress management table (`KK_T_PRG`) using SQL define key `KK_SELECT_025` with 4 bind variables (service contract number, status change classification, progress status, progress date/time). |

**CRUD Classification:** The method performs exactly one database operation — a **Read (R)** — via `selectBySqlDefine`. There are no Create, Update, or Delete operations. The `KK_T_PRG` table is the progress tracking table used by the batch process to record and query the execution state of address change formatting cell order updates.
