Oracleクエリーを実行するパラメータを使用してWebサービスを作成します。

Question

.NETテクノロジはまったく新しいです。私は自分の要求をどのように進めるのか混乱しています。私は、サービスが呼び出されたときに実行する必要がある複雑なOracleクエリーを持っています。私はちょうど以下の質問のサンプルを与えています。

STPR_STUDY.STD_REF IN（？）のWebサービスでパラメータにする必要があるクエリインチ私が試みてきたのは、WEB APIを使用してMVC ASP.NETアプリケーションを作成することです。私が正しく物事をやっている場合、私は解決策にしてDapplerネットistalledいる

using System.Net; 
using System.Net.Http; 
using System.Web.Http; 
namespace ProConn.Controllers 
{ 
public class ProQueryController : ApiController 
{ 
    public string Get() 
    { 
     var strQuery = @"The above query"; 
     OracleConnection dbConn = new OracleConnection("DATA SOURCE=ABC;PASSWORD=ABCD;PERSIST SECURITY INFO=True;USER ID=ABCDE"); 

     dbConn.Open(); 

     dbConn.Close(); 

     return strQuery; 
    } 
} 
} 

とコントローラを作成しようとすると、現在のモデルクラス

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 

namespace ProConn.Models 
{ 
public class ProStudyData 
{ 
    public string CATEGORY; 
    public int SESSION_NUMBER; 
    public DateTime SESSION_START_DATE; 
    public DateTime SESSION_START_TIME; 
    public DateTime SESSION_END_DATE; 
    public DateTime SESSION_END_TIME; 
    ....... 

を作成し、私は私が持っている、わかりませんフォーラムや記事を見て一緒にしようとしています。また、私はJSON形式でデータを返す必要がありますが、他の質問ではDTOを使用するように提案されました。誰も私にどのように進むことができますか教えてください

Answer 1

あなたは実際にクエリを実行していません。私はあなたが返すようにしようとしているが、DataTableのに選択からデータを取得すると、あなたが操作してみましょうか、.NET

using Oracle.ManagedDataAccess.Client; 
using System.Data; 
using Newtonsoft.Json; 
    public string Get() 
    { 
     var strQuery = @"The above query"; 

     OracleConnection dbConn = new OracleConnection("DATA SOURCE=ABC;PASSWORD=ABCD;PERSIST SECURITY INFO=True;USER ID=ABCDE"); 

     dbConn.Open(); 

     OracleCommand selectCommand = new OracleCommand(strQuery, dbConn); 
     OracleDataAdapter adapter = new OracleDataAdapter(selectCommand); 
     DataTable selectResults = new DataTable(); 
     adapter.Fill(selectResults); 

     dbConn.Close(); 
     return JsonConvert.SerializeObject(selectResults); 
    }
