## 1. Role

### JBSbatKKSvkeiDelTgCst.executeKK_T_ODR_SET_KK_SELECT_011()

This method performs a parameterized database query (SELECT) against the **Order Setup** table (`KK_T_ODR_SET`) to retrieve order setup records matching specific service contract and order criteria. It is part of a batch processing service (`JBSbatKKSvkeiDelTgCst`) responsible for extracting **service contract deletion targets** — i.e., identifying which service contracts should be deleted based on deletion processing type and deletion target type. The method implements the **Data Access Object (DAO) delegation pattern**, acting as a thin wrapper around the `JBSbatSQLAccess.selectBySqlDefine()` framework method. It receives an array of bind variables (service contract number, service contract detail number, order type code, and service order code), packages them into a `JBSbatCommonDBInterface` parameter list, and dispatches the SQL query using the pre-defined SQL key `KK_SELECT_011`. This method serves as a shared internal utility called by the main batch processing flow during deletion target extraction, and is not directly invoked by any screen or external caller.

## 2. Processing Pattern (Detailed Business Logic)

```mermaid
flowchart TD
    START(["executeKK_T_ODR_SET_KK_SELECT_011(param[])"])
    STEP1["Generate bound variable list"]
    STEP2["Create JBSbatCommonDBInterface paramList"]
    STEP3["Set param[0] - Service Contract Number"]
    STEP4["Set param[1] - Service Contract Detail Number"]
    STEP5["Set param[2] - Order Type Code"]
    STEP6["Set param[3] - Service Order Code"]
    STEP7["Execute DB SELECT via selectBySqlDefine(paramList, KK_SELECT_011)"]
    END_NODE(["Return void / Next"])

    START --> STEP1 --> STEP2 --> STEP3 --> STEP4 --> STEP5 --> STEP6 --> STEP7 --> END_NODE
```

**Processing Summary:**

The method follows a straightforward linear flow with no conditional branches:

1. **Bind Variable List Generation** — Create a new `JBSbatCommonDBInterface` object to serve as the parameter list for the SQL query.
2. **Bind Variable Population** — Sequentially append all four bind variables from the `param` array onto the parameter list. The method expects exactly 4 elements in the array, each containing a `String` value representing a search key.
3. **Database Query Execution** — Invoke `selectBySqlDefine()` on the `db_KK_T_ODR_SET` SQL access instance, passing the populated parameter list and the SQL key `KK_SELECT_011`. This triggers the framework's SQL mapping engine to execute the pre-configured SELECT statement against the `KK_T_ODR_SET` table with the provided bind variables.
4. **Return** — The method returns `void` (the query results are consumed by the caller via the result-handling framework, not returned directly).

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | `Object[]` | Array of bind variable values for the SQL SELECT query. Must contain exactly 4 elements in the following order: (1) Service Contract Number, (2) Service Contract Detail Number, (3) Order Type Code, (4) Service Order Code. Each element is converted to a `String` and used as a WHERE clause filter in the database query. |

**External State Read:**

| # | Field | Type | Business Description |
|---|-------|------|---------------------|
| 1 | `db_KK_T_ODR_SET` | `JBSbatSQLAccess` | Database access layer for the `KK_T_ODR_SET` (Order Setup) table. Initialized in `initial()` with the common batch parameters. Used to execute the SELECT query via `selectBySqlDefine()`. |

## 4. CRUD Operations / Called Services

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

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| - | `JBSbatCommonDBInterface.setValue` | JDKStructuredMap | - | Calls `setValue` in `JBSbatCommonDBInterface` to append bind variable values to the parameter list |
| - | `JBSbatSQLAccess.selectBySqlDefine` | JBSbatSQLAccess | KK_T_ODR_SET | Calls `selectBySqlDefine` to execute the pre-configured SQL query identified by key `KK_SELECT_011` |

**CRUD Classification:**

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `db_KK_T_ODR_SET.selectBySqlDefine` | - | `KK_T_ODR_SET` | Read operation — Executes a SELECT query against the Order Setup table (`KK_T_ODR_SET`) using SQL key `KK_SELECT_011`. Retrieves order setup records matching the bind variable filters (service contract number, service contract detail number, order type code, service order code). |

## 5. Dependency Trace

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

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

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: JBSbatKKSvkeiDelTgCst (internal) | `JBSbatKKSvkeiDelTgCst.executeKK_T_ODR_SET_KK_SELECT_011(Object[])` | `selectBySqlDefine [R] KK_T_ODR_SET` |

**Call Chain Detail:**

The method is called internally from within `JBSbatKKSvkeiDelTgCst` during the main batch processing flow. It is invoked in the deletion target extraction section where the batch builds a WHERE clause to filter order setup records matching the current processing parameters. The caller constructs the `param` array from the current iteration's service contract number, service contract detail number, order type code, and service order code.

## 6. Per-Branch Detail Blocks

> This method contains no conditional branches (no if/else, switch/case, loops, or try/catch). It follows a single linear execution path.

**Block 1** — [LINEAR EXECUTION] (L657)

> Generate bind variable list and populate parameter array with all 4 bind variables.

| # | Type | Code |
|---|------|------|
| 1 | SET | `paramList = new JBSbatCommonDBInterface()` // Create bound variable list [-> new JDBC parameter container] |
| 2 | EXEC | `paramList.setValue(param[0].toString())` // Set Service Contract Number [bind variable index 0] |
| 3 | EXEC | `paramList.setValue(param[1].toString())` // Set Service Contract Detail Number [bind variable index 1] |
| 4 | EXEC | `paramList.setValue(param[2].toString())` // Set Order Type Code [bind variable index 2] |
| 5 | EXEC | `paramList.setValue(param[3].toString())` // Set Service Order Code [bind variable index 3] |

**Block 2** — [LINEAR EXECUTION] (L664)
