## 1. Role

### JBSbatKKKDDIAnkenChsht.executeKK_T_KDDI_TJGWR_KJKS_KK_SELECT_002()

This method serves as the **database access layer** for querying the **KDDI third-party provider contract status inquiry table** (`KK_T_KDDI_TJGWR_KJKS`) in the batch processing pipeline that extracts KDDI next-case (次案件) data. The batch job `JBSbatKKKDDIAnkenChsht` is a batch-level business service responsible for extracting cases related to KDDI third-party provider discounts and contract statuses — specifically handling contract management correspondence as per change request ANK-1373-00-00.

This method does **not** perform any conditional branching or business-rule routing; it is a pure data-fetching operation that wraps a single SQL SELECT statement defined by the SQL key `KK_SELECT_002`. Its role in the larger system is to retrieve contract status records from the KDDI inquiry table within specified date ranges for multiple service categories (eo Light Net, eo Light Phone, eo Light TV), filtering by application-effective periods and activity result flags. The caller method (`execute()`) constructs a 12-element parameter array with date range values and invokes this method to populate the result set, which is then written to an output file (`insertKDDIRslt()`).

The method implements the **delegation pattern** — it delegates all SQL execution to the `JBSbatSQLAccess.selectBySqlDefine()` framework method, which maps to a pre-configured SQL definition in the batch framework's SQL management layer. It acts as an internal utility method (private visibility), called exclusively from the batch's `execute()` entry point during the main processing loop.

```

**Processing flow description:**

1. **Generate parameter list** — A `JBSbatCommonDBInterface` object (`paramList`) is instantiated to serve as a bind-variable container for the SQL query. This is the standard batch framework mechanism for passing parameters to SQL definitions.

2. **Set bind variables (indices 0–11)** — Each element of the input `param` array (cast to `String` via `toString()`) is sequentially added to `paramList` via `setValue()`. The 12 bind variables represent date-range filter pairs covering:
   - Contract status inquiry status application period (start/end)
   - eo Light Net contract status application period (start/end)
   - eo Light Phone contract status application period (start/end)
   - eo Light TV contract status application period (start/end)
   - Activity result application period (start/end)
   - NG reason application period (start/end)

3. **Execute SQL SELECT** — The method invokes `db_KK_T_KDDI_TJGWR_KJKS.selectBySqlDefine()` with the populated parameter list and the SQL key `KK_SELECT_002`. This executes the pre-defined SELECT query against the `KK_T_KDDI_TJGWR_KJKS` table, using all 12 date-range filters to narrow down the result set.

4. **Return** — No value is returned. Results are stored in the framework's result context (managed by `JBSbatSQLAccess`) for subsequent retrieval by the caller (`insertKDDIRslt()` in `execute()`).

| `db_KK_T_KDDI_TJGWR_KJKS` | `JBSbatSQLAccess` | Database access clause for the KDDI third-party provider discount contract status inquiry table (`KK_T_KDDI_TJGWR_KJKS`). Initialized in `initial()` with the table name constant `D_TBL_NAME_KK_T_KDDI_TJGWR_KJKS`. |

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `db_KK_T_KDDI_TJGWR_KJKS.selectBySqlDefine` | - | `KK_T_KDDI_TJGWR_KJKS` | Reads records from the KDDI third-party provider discount contract status inquiry table using the pre-defined SQL query `KK_SELECT_002`, filtered by 12 date-range bind variables covering contract status inquiry, eo Light Net/Phone/TV service statuses, activity results, and NG reasons. |

**CRUD Classification:** This method performs a **Read (R)** operation only. It queries the `KK_T_KDDI_TJGWR_KJKS` table to retrieve contract status inquiry records matching the specified date-range criteria. No insert, update, or delete operations are performed.

## 5. Dependency Trace

### Pre-computed evidence from code analysis graph:

No screen/batch entry points found within 8 hops. Direct callers found: 1 methods.
Terminal operations from this method: `selectBySqlDefine` [R] `KK_T_KDDI_TJGWR_KJKS`

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: `JBSbatKKKDDIAnkenChsht.execute()` | `JBSbatKKKDDIAnkenChsht.execute()` -> `executeKK_T_KDDI_TJGWR_KJKS_KK_SELECT_002()` | `selectBySqlDefine [R] KK_T_KDDI_TJGWR_KJKS` |

**Caller details:**

The only direct caller is `JBSbatKKKDDIAnkenChsht.execute()`, the batch's main processing entry point. Within `execute()`, a 12-element `Object[]` array (`whereParamKDDITjgwrKjks`) is constructed with date-range values (indices 0-7 receive the same date values as `commonItem.getOpeDate()`, indices 8-11 also receive `commonItem.getOpeDate()` for activity result and NG reason application periods). The array is passed to `executeKK_T_KDDI_TJGWR_KJKS_KK_SELECT_002()`, and the resulting data is subsequently processed by `insertKDDIRslt()` to write KDDI case results to an output file.
