使用c＃odbc插入記錄在oracle數據庫中

Question

我在C＃中搞亂了解如何將記錄插入到使用C＃ODBC的數據庫中。我已經學會了如何將記錄讀入DGV，但是現在我陷入了插入。 我的代碼正在做什麼的快速概覽，它從表中讀取20行到DGV，然後它應該將相同的行插入到不同的表中。

我使用VS 2012和SQL Developer（Oracle）。

這裏是我的表單代碼：

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace WindowsFormsApplication13 
{ 
public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     for (int rows = 0; rows < 20; rows++) 
     { 
      dataGridView1.Rows.Add(); // adding needed amount of rows 

      for (int cols = 0; cols < 13; cols++) 
      { 
       this.dataGridView1[cols, rows].Value = getNumberOfThreads(rows, cols); 
      } 
     } 
     StringBuilder sql = new StringBuilder(); 

     sql.AppendLine("insert into chsarp_test_table"); 
     sql.AppendLine("SELECT *"); 
     sql.AppendLine("FROM legal_transactions"); 
     sql.AppendLine("WHERE rownum between 1 and 25"); 

     //using (DataTable dt = Database.GetData(sql.ToString())) 
     // if (dt.Rows.Count > 0) 
     // Database dt = new Database.SetData(sql.ToString()); 
     Database.SetData(sql.ToString()); 
    } 

    public static string getNumberOfThreads(int i, int j) 
    { 

     StringBuilder sql = new StringBuilder(); 
     sql.AppendLine("SELECT *"); 
     sql.AppendLine("FROM legal_transactions"); 
     sql.AppendLine("WHERE rownum between 1 and 25"); 

     using (DataTable dt = Database.GetData(sql.ToString())) 
      if (dt.Rows.Count > 0) 
       return dt.Rows[i][j].Equals(DBNull.Value) ? "null" : dt.Rows[i][j].ToString(); 

     return "null"; 
    } 
} 

} 

這裏是我的類代碼：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Data.Odbc; //used for the ODBC stuff 
using System.Data; // Used for public static datatable 
using System.Windows.Forms; 

namespace WindowsFormsApplication13 
{ 
class Database 
{ 

    private const string connOdbc = "dsn=atlas32;uid=NAME;pwd=XXXX"; 
    private const string cnnOLE = "provider =XXXX;User ID = NAME;password = XXXX; Data Source = XXX Properties=;Persist Security Info=False"; 

    public static DataTable GetData(string Sql) 
    { 
     DataTable dt = new DataTable(); 
     try 
     { 
      OdbcConnection cnn = GetConnection(); 
      using (OdbcDataAdapter da = new OdbcDataAdapter(Sql, cnn)) 
      { 
       da.SelectCommand.CommandTimeout = 0; 
       da.Fill(dt); 
      } 
      CloseConnection(cnn); 
     } 
     catch (Exception ex) 
     { 
      //Queries.LogErrors(ex.Message, Sql); 
      MessageBox.Show("Error 1"); 

     } 
     return dt; 
    } 

    public static void SetData(string sql) 
    { 

     try 
     { 
      OdbcConnection cnn = GetConnection(); 
      using (OdbcCommand cmd = new OdbcCommand(sql, cnn)) 
       cmd.ExecuteNonQuery(); 

      CloseConnection(cnn); 
     } 
     catch (Exception ex) 
     { 
      //Queries.LogErrors(ex.Message, sql); 
      MessageBox.Show("Error 2"); 
     } 

    } 

    private static OdbcConnection GetConnection() 
    { 
     try 
     { 
      OdbcConnection cnn = new OdbcConnection() { ConnectionString = connOdbc }; 
      cnn.Open(); 
      return cnn; 
     } 
     catch (Exception ex) 
     { 
      //throw ex; 
     } 
     return null; 
    } 

    private static void CloseConnection(OdbcConnection Connection) 
    { 
     try 
     { 
      if (Connection.State == ConnectionState.Open) 
       Connection.Close(); 
       Connection.Dispose(); 
     } 
     catch (Exception ex) 
     { 
      //throw ex; 
     } 
     Connection = null; 
    } 

} 

} 

我試圖單步執行代碼和它的股價下跌在SetDataMethod上ExecuteNonQuery。我試圖研究這一點，但不介意任何幫助我的信息，任何推向正確的方向將不勝感激。

我錯過了插入的表上的Schema。在問題的評論部分@stuartd的幫助下發現了這一點。
