データベース内のいくつかのテーブルから一連の値を取得しようとしています。

現在、このコードが機能しています：

SqlDataReader reader = null;
SqlCommand myCommand = new SqlCommand("select * from ods_LN_Master", xavierConnection);

reader = myCommand.ExecuteReader();
while (reader.Read())
{
   Console.WriteLine(reader["LMBKNO"].ToString());
}

ただし、私が本当にやりたい SQL クエリは次のようになります。

select "T1"."C0" AS "Collateral Type", "T1"."C1" AS "Owner Occuppied", "T1"."C2" AS "County Name", "T1"."C3" AS "Region Description", "T1"."C4" AS "City", "T1"."C5" AS "Orig Appraisal Date", "T1"."C6" AS "Curr Appraisal Date", "T1"."C7" AS "Mortgage 1 Bank", "T1"."C8" AS "Mortgage 2 Bank", "T1"."C9" AS "Bank Owned Mortgage 1", "T1"."C10" AS "Bank Owned Mortgage 2", "T1"."C11" AS "Call Report Code", "T1"."C12" AS "Original Note Date", "T1"."C13" AS "Account Key", "T1"."C14" AS "Account Number", "T1"."C15" AS "Credit Risk Code", "T1"."C16" AS "Current FICO Score", "T1"."C17" AS "Original FICO Score", "T0"."C18" AS "Bank Owned Principal Assets", "T0"."C19" AS "Orig Appraisal Amount", "T0"."C20" AS "Curr Appraisal Amount", "T0"."C21" AS "Mortgage Amount 1", "T0"."C22" AS "Mortgage Amount 2", "T1"."C18" AS "Available Balance", "T1"."C19" AS "Past Due Counter 1", "T1"."C20" AS "Past Due Counter 2", "T1"."C21" AS "Past Due Counter 3", "T1"."C22" AS "Past Due Counter 4", "T1"."C23" AS "Past Due Counter 5", "T1"."C24" AS "Past Due Counter 6"

私の会社がデータベース内のものを見るために使用する別のプログラムから自動生成されました。探している正確なデータが返されることを知っています。データベース スキーマについてはまだ理解していないので、とりあえずこの SQL を使用したいと思います (そして、かなり長い間使用していません。その巨大な....")

見苦しい SQL クエリを C# コードに取り込み、単純なステートメントと同じように動作させるにはどうすればよいでしょうか?

私の現在の問題は、二重引用符にあります。それを機能させるためにできる検索/置換はありますか?

それをコピーしてストアド プロシージャに貼り付け、 ADO.NETを使用してストアド プロシージャを呼び出します。

編集：

using (var conn = new SqlConnection("<connection string>")) {
    using (var cmd = new SqlCommand("MyStoredProcedureName")) {
        cmd.CommandType = CommandType.StoredProcedure;
        SqlDataReader reader = cmd.ExecuteReader();
        while (reader.Read())
        {
            // Use the reader to read data
        }
    }
}

参考までに、ストアド プロシージャを使用せずにこれを行う別の方法は、プロジェクトに新しいテキスト ファイルを作成し、そのテキスト ファイルに SQL をコピー アンド ペーストすることです。テキスト ファイルのビルド アクションを Embedded Resource に変更し、GetManifestResourceStreamを使用してリソースから SQL をプルします。

このように：

string sql = "";
using (StreamReader reader = new StreamReader(Assembly.GetExecutingAssembly().
       GetManifestResourceStream("<AssemblyName>.<NameOfTextFile>")) {
    sql = reader.ReadToEnd();
}

if (!string.IsNullOrEmpty(sql))
{
    using (var conn = new SqlConnection("<connection string>")) {
        using (var cmd = new SqlCommand(sql)) {
            cmd.CommandType = CommandType.Text;
            SqlDataReader reader = cmd.ExecuteReader();
            while (reader.Read())
            {
                // Use the reader to read data
            }
        }
    }
}
