このドキュメントでは、次の表で示すサンプルのプログラムとデータエリアについて説明します。 ソースコードはインストール中に提供され、SYSSPT ライブラリに配置されます。
ストアドプロシージャのリンクルーチン STPLNK01、STPLNK02、および STPLNK03 については、「例」を参照してください。
| 名前 | 説明 |
|---|---|
| SAMPINT1 | このプログラムは、トリガを起動するコマンドを発行し、特定のファイルに対するレコードの更新または格納が書き込まれると、追加処理を実行します。 |
| SAMPPRC1 | SAMPINT1 のストアドプロシージャバージョンです。 データはパラメータとして渡され、このパラメータから抽出された情報が返されます。 |
| SAMPP001 | SAMPPRC1 から呼び出されるストアドプロシージャです。 入力パラメータからの情報を使用して、コール元に返す追加情報を抽出して作成します。 |
| STPLCB | STPLNK02 や STPLNK03 などのサンプルルーチンで、ローカルデータエリア（LDA）として使用される Adabas ACB コントロールブロックレイアウトです。 |
| STPLCBE | ローカルデータエリア（LDA）として使用される Adabas ACBX コントロールブロックレイアウトです。 |
| STPLRBE | レコードバッファ抽出ルーチン（STPRBE）が呼び出されるときに使用する必要のあるパラメータデータエリア（PDA）のサンプルレイアウトです。 |
| STPUTPRM | サブプログラム STPUTRAK に渡されるパラメータデータエリアの例です。 |
| STPUTRAK | プロシージャを実行する要求を受け取ったときに、Natural トリガドライバが呼び出すルーチンです。 このルーチンは、トリガメンテナンスプロファイルでトリガアクティビティの記録オプションが active に設定されている場合のみ呼び出されます。 このルーチンの名前は変更しないでください。 |
| STPAPARM | プロシージャが呼び出されるときに、Natural トリガドライバから渡されるパラメータデータエリア（PDA）のサンプルレイアウトです。 |
| STPAPRM1 | プロシージャが呼び出されていて、STPUTRAK が拡張情報も渡すことを要求したときに、Natural トリガドライバから渡されるパラメータデータエリア（PDA）のサンプルレイアウトです。 拡張エリアの長さは、250 バイトです。 トリガドライバのグローバルデータエリア（GDA）の一部として保守され、トリガドライバによるプロシージャの呼び出し間で変更されません。 |
| SAMP0001 | SAMPINT1 から発行されるコマンドで起動するトリガの結果として呼び出されるプロシージャです。 |
| SAMP0002 | CONTACTS ファイルに対して発行されるすべてのコマンドで呼び出されるプロシージャです。CONTACTS ファイルは、SAMPINT1 プログラムのサンプルファイルとして使用されます。 このプロシージャは、すべてのコマンドを監査するために、メッセージを CMPRINT に書き込み、監査ファイルにログレコードを作成します。 |
| SAMP0003 | SAMP0002 と同様に、このプロシージャは、CONTACTS ファイルに対して発行されるコマンドを監査します。ただし監査対象は、関係のあるコマンドのみです。 |
| SAMP0004 | VEHICLES ファイルに対して行われるあらゆる削除で、SAMPREF1 ルーチンが実行されるときに呼び出されるプロシージャです。 参照ロジックタイプが Restrict であるサンプルアプリケーションです。 |
| SAMP0005 | EMPLOYEES ファイルに対する更新で、SAMPREF2 ルーチンが実行されるときに呼び出されるプロシージャです。 これは、参照保全タイプが Cascade の場合の例です。 |
| SAMPREF1 | このルーチンは、VEHICLES ファイルの参照保全性の検証を実行するトリガを呼び出すコマンドを発行します。 関連するプロシージャは SAMP0004 です。このプロシージャは、削除されるレコードで制限チェックを実行します。 |
| SAMPREF2 | このルーチンは、EMPLOYEES ファイルでプライマリキーに対する更新の参照保全検証を実行するトリガを呼び出すコマンドを発行します。 関連するプロシージャは SAMP0005 です。このプロシージャは、VEHICLES と MISCELLANEOUS ファイルの外部キーのプライマリキーに対するあらゆる更新をカスケードします。 |
