SQLステートメントとパラメータを組み合わせて実行可能なSQLを整形する
私は、サーバの開発で iBatis を利用することが多いのですが、
log4j を利用することで、SQLのステートメントとパラメータの両方が、
出力されるようになっています。

■出力例
yyyy-mm-dd hh:mmConfuseds,mmm DEBUG [java.sql.Connection] [http-8080-2] [********************] - {conn-NNNNNNN} Preparing Statement: SELECT * FROM EMP_MST WHERE EMP_CD = '?'
yyyy-mm-dd hh:mmConfuseds,mmm DEBUG [java.sql.PreparedStatement] [http-8080-2] [*******************] - {pstm-NNNNNN} Parameters: [A0001]

テストの際などに、サーバ処理の中で利用されたSQLを、
改めて、DBに対して直接投げてみたい、ということがよくあります。
そのためには、このステートメントとパラメータを組み合わせてSQLを作り直す必要があるのですが、
パラメータ数が多いといちいち「?」を置換して整形するのが面倒なので、
下記のようなサンプルで組み立てるようにしています。


Code:
{curl 8.0 applet}
{curl-file-attributes character-encoding = "utf8"}
{import * from CURL.DESKTOP.CLIPBOARD}
{def sql-ta:TextArea =
    {TextArea
        ||width = {make-elastic preferred-size = 1in},
        height = {make-elastic preferred-size = 1in}
    }
}


{def param-ta:TextArea =
    {TextArea
        ||width = 7in,
        height = {make-elastic preferred-size = 0.5in}
    }
}

{def comp-ta:TextArea =
    {TextArea
        ||width = 7in,
        height = {make-elastic preferred-size = 0.5in}
    }
}


{define-proc {get-type-list
                 index:int,
                 val:String,
                 params:StringArray
             }:DropdownList

    || ■CHAR
    || ■NUMBER
    || ■VARCHAR2
    || ■TIMESTAMP
    || ■DATE

    def dl =  {DropdownList
                  name = val,
                  user-data = index,
                  "文字列",
                  "数値",
                  {on ValueChanged at dl:DropdownList do
                      {switch dl.value
                       case  "文字列" do
                          set params[dl.user-data asa int] = "\'" & {dl.name.trim-clone} &  "\'"
                       else
                          set params[dl.user-data asa int] = {dl.name.trim-clone} asa String
                      }
                  }
              }

    {if {String {val.to-int}} == val then
        {dl.set-value-with-events "数値"}
    elseif  {String {val.to-double}} == val then
        {dl.set-value-with-events "数値"}
    else
        {dl.set-value-with-events "文字列"}

    {Frame
        hstretch? = true,

            margin = 5pt, spacing = 3pt,
            {GroupBox
                label = "■SQL Templete",
                height = null,
                sql-ta
            },
            {HBox
                {GroupBox

                comp-ta
            }
        }
    },
    visibility = "normal",
    {on WindowClose do
        {exit}
    }
}


■使い方
①「SQL Templete」のテキストエリアにステートメントを張り付ける
②「Parameter」のテキストエリアにパラメータを張り付ける
③「解析」ボタンを押す
④必要に応じて「Type Select」に表示される型と値の組み合わせを修正する
⑤「置換」ボタンを押して、ステートメントとパラメータを整形します
⑥「Executable SQL」に出力されたSQLを利用する
 (「クリップボードへコピー」ボタンでコピー可能)


もしかすると、SQL Developer などのツールであれば、
もっとうまくやってくれる機能がありそうな気もしますが・・・。
