## 1. Role

### JBSbatKKSkaLckDteEdit.executeKK_T_IDO_RSV_KK_SELECT_114()

This method performs a database **read (SELECT)** operation against the **工事予約 (Construction Reservation)** table — `KK_T_IDO_RSV` — using a pre-defined SQL key (`KK_SELECT_114`). It serves as a targeted data retrieval bridge within the batch processing layer, converting a raw `Object[]` parameter array into a structured database query parameter object (`JBSbatCommonDBInterface`) and executing the select. The method takes the construction project number (工事案件番号) from the first element of the parameter array and uses it as a bind variable to filter records from the reservation table. Its role in the larger system is a **delegate query method** — it is a private helper invoked by the batch's main `execute()` method to fetch reservation records associated with a specific construction project, enabling downstream batch processing steps that depend on reservation data for scheduling or coordination.

**Processing summary (based on Javadoc — Javadoc: SQLKEY(KK_SELECT_114)でDBアクセスを行います。):**
1. **Bind variable setup** (引数でバイント変数を設定します。): A `JBSbatCommonDBInterface` parameter list is instantiated and the construction project number from `param[0]` is set as the bind variable.
2. **DB access execution** (DBアクセスを実行します。): The `db_KK_T_IDO_RSV` data access object executes a SQL select using the predefined SQL key `KK_SELECT_114` with the populated parameter list.
3. **Return** (メソッドの呼び出し方です): The method returns `void` after the DB call completes. No transformation or routing logic is present — this is a pure delegation.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | `Object[]` | An array of bind variables for the SQL query. The method expects the first element (`param[0]`) to contain the **construction project number** (工事案件番号 — a unique identifier for a construction project) as an `Object` that can be cast to `String` via `toString()`. This number is used to filter construction reservation records from the `KK_T_IDO_RSV` table. |

**Instance fields read:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `db_KK_T_IDO_RSV` | `JBSbatCommonDBInterface` | Database access delegate for the construction reservation table (`KK_T_IDO_RSV`). Provides the `selectBySqlDefine` method that executes parameterized SQL queries. |

## 4. CRUD Operations / Called Services

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

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `selectBySqlDefine` | `-` | `KK_T_IDO_RSV` | Reads construction reservation records from the `KK_T_IDO_RSV` table using the SQL key `KK_T_IDO_RSV_KK_SELECT_114`, filtered by the construction project number bind variable. |

An analysis of the called methods:

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `db_KK_T_IDO_RSV.selectBySqlDefine` | `-` | `KK_T_IDO_RSV` | Execute SQL SELECT defined by `KK_SELECT_114` against the construction reservation table (`KK_T_IDO_RSV`), passing the construction project number as a bind variable. Returns matching reservation rows into the parameter list. |

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: `JBSbatKKSkaLckDteEdit` | `JBSbatKKSkaLckDteEdit.execute()` → `executeKK_T_IDO_RSV_KK_SELECT_114(param)` | `selectBySqlDefine [R] KK_T_IDO_RSV` |

## 6. Per-Branch Detail Blocks

This method has **no conditional branches** — it is a straight-line sequence of exactly three operations.

**Block 1** — [SET] `(L262)`

> Instantiate the database parameter container and set the construction project number bind variable.

| # | Type | Code |
|---|------|------|
| 1 | SET | `JBSbatCommonDBInterface paramList = new JBSbatCommonDBInterface();` // Create bind variable list (バイント変数のリストを生成します) |
| 2 | EXEC | `paramList.setValue(param[0].toString());` // Set the construction project number (工事案件番号) as the first bind variable |

**Block 2** — [CALL] `(L266)`

> Execute the database select query.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `db_KK_T_IDO_RSV.selectBySqlDefine(paramList, KK_T_IDO_RSV_KK_SELECT_114);` // DB accessを実行します — Execute DB access using SQL key KK_SELECT_114 against KK_T_IDO_RSV |
