## 1. Role

### JBSbatKKAdChgSodUpd.executeKK_T_ADCHG_DTL_KK_SELECT_014()

This method is a **data retrieval gateway** for the Address Change (住所変更) service order processing pipeline. Its sole business purpose is to query the **Address Change Detail** table (`KK_T_ADCHG_DTL`) using the SQL key `KK_SELECT_014`, binding up to 112 parameters that collectively form a set of eight search-condition tuples. Each tuple represents a distinct address change record lookup, combining fields such as the order dispatch trigger classification, reservation effective date, parent contract identification code, address change detail type code, address change number, and pre/post change identification numbers.

The method implements the **data-binding-then-execute** pattern common to this enterprise batch framework: it accepts a flat `Object[]` array of raw bind variables, wraps each in a `JBSbatCommonDBInterface` parameter list, and delegates to `db_KK_T_ADCHG_DTL.selectBySqlDefine()` for the actual SQL execution. No conditional branching, transformation, or business logic enrichment occurs within this method — it is a pure, sequential data-binding and query dispatch mechanism.

Its role in the larger system is that of an **internal helper** called by the parent `execute()` method of `JBSbatKKAdChgSodUpd`, which orchestrates the broader address change service order update workflow. The caller (at line 560) constructs the 112-element String array with specific values reflecting the current address change context — order dispatch trigger classifications (`ODR_EXEC_DIV_DSL_FIN`, `ODR_EXEC_DIV_NEW_FIN`), parent contract codes (`KKTK_OYA_KEI_SKBT_CD_SVC_KEI`, `KKTK_OYA_KEI_SKBT_CD_SVC_KEI_UCWK`, `OP_OYA_KEI_SKBT_CD_SVC_KEI`, `OP_OYA_KEI_SKBT_CD_SVC_KEI_UCWK`), address change detail type codes (`ADCHG_DTL_SBT_CD_KKTK`, `ADCHG_DTL_SBT_CD_SVC_KEI`, `ADCHG_DTL_SBT_CD_OP`), and service key numbers — to retrieve matching detail records for subsequent processing.

## 2. Processing Pattern (Detailed Business Logic)

```mermaid
flowchart TD
    START(["executeKK_T_ADCHG_DTL_KK_SELECT_014(params)"])
    START --> BIND_PARAM["Generate bind variable list<br/>JBSbatCommonDBInterface paramList = new JBSbatCommonDBInterface()"]
    BIND_PARAM --> BIND_LOOP["Bind param[0]..param[111] to paramList<br/>112 setValue() calls<br/>param[i].toString()"]
    BIND_LOOP --> EXEC_SQL["Execute DB access<br/>db_KK_T_ADCHG_DTL.selectBySqlDefine(paramList, KK_SELECT_014)"]
    EXEC_SQL --> END_NODE(["Return (void)"])
```

**Processing steps:**

1. **Bind Variable List Generation**: Creates a new `JBSbatCommonDBInterface` object to hold the bound parameters. This object acts as the PreparedStatement parameter container for the JDBC layer.
2. **Sequential Parameter Binding (L1454–L1557)**: Iteratively binds all 112 elements of the `param` array by calling `paramList.setValue(param[i].toString())` for indices 0 through 111. Each `toString()` conversion ensures the raw Object value is converted to a String suitable for SQL bind variable population. Some elements are added via change-order patches (identified by comments `OT-2013-000311`, `ANK-1578-00-00`, `IT2-2014-0000180`).
3. **DB Access Execution (L1573)**: Executes the SQL query defined by the SQL key `KK_SELECT_014` against the `KK_T_ADCHG_DTL` table, passing the fully populated `paramList`. The query returns matched address change detail records, the result of which is consumed by the caller.
4. **Return**: Returns void. No data transformation or result extraction is performed within this method.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | `Object[]` | An array of 112 bind variable values passed in order. Each element corresponds to a SQL placeholder in the `KK_SELECT_014` query. The caller constructs this array with specific address change detail search criteria including: order dispatch trigger classification (e.g., `ODR_EXEC_DIV_DSL_FIN`, `ODR_EXEC_DIV_NEW_FIN`), reservation effective date (`opeDate`), parent contract identification codes for different service types (DSL, SVC, KKTK, OP), address change detail type codes (KKTK, SVC_KEI, OP), address change number (`inAdchgNo`), and conditional service key numbers for pre-change (`cndDslSvcKeiNo`) and post-change (`cndNewSvcKeiNo`) lookups. |

**Instance fields read by this method:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `db_KK_T_ADCHG_DTL` | `JBSbatSQLAccess` | Database access object for the `KK_T_ADCHG_DTL` table, initialized in the parent class constructor to handle SQL operations against the Address Change Detail table |

## 4. CRUD Operations / Called Services

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

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `db_KK_T_ADCHG_DTL.selectBySqlDefine` | — | `KK_T_ADCHG_DTL` | Selects address change detail records from the database using the SQL key `KK_SELECT_014` and the 112-element bind parameter list |

**Analysis:**
- This method performs a **Read (R)** operation exclusively. It calls `selectBySqlDefine()` on the `JBSbatSQLAccess` instance `db_KK_T_ADCHG_DTL`, which is configured to access the `KK_T_ADCHG_DTL` (Address Change Detail) table.
- The SQL key `KK_SELECT_014` is a predefined SQL definition that selects address change detail records matching the 112 bind parameters. The query searches across multiple address change detail type combinations (KKTK, SVC_KEI, OP) and both pre-change and post-change service key identifiers.
- No Create, 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_ADCHG_DTL).

Trace who calls this method and what this method ultimately calls.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: JBSbatKKAdChgSodUpd.execute() | `JBSbatKKAdChgSodUpd.execute()` -> `executeKK_T_ADCHG_DTL_KK_SELECT_014` | `selectBySqlDefine [R] KK_T_ADCHG_DTL` |

**Instructions:**
- The single direct caller is `JBSbatKKAdChgSodUpd.execute()` at line 560, which constructs the 112-element String array with specific search criteria and passes it to this method.
- This method is an internal helper within the batch service component; no external screen or batch entry point is directly connected.
- The terminal operation is a database read (`selectBySqlDefine`) against the `KK_T_ADCHG_DTL` table.
