錯誤「令牌UKNOWN」在Borland的

Question

你好，我得到了錯誤：

Token unknown - line 1, char 74

當我試圖讓與SQL注入的查詢時，不帶參數我沒有任何問題，這裏是代碼：

DbProviderFactory factory= DbProviderFactories.GetFactory("Borland.Data.AdoDbxClient"); 

     IDbConnection c = factory.CreateConnection(); 
     c.ConnectionString = "DriverName=Interbase;Database=....;RoleName=RoleName;User_Name=...;Password=......;SQLDialect=1;MetaDataAssemblyLoader=Borland.Data.TDBXInterbaseMetaDataCommandFactory,Borland.Data.DbxReadOnlyMetaData,Version=11.0.5000.0,Culture=neutral,PublicKeyToken=91d62ebb5b0d1b1b;GetDriverFunc=getSQLDriverINTERBASE;LibraryName=dbxint30.dll;VendorLib=GDS32.DLL"; 
     c.Open(); 

     IDbCommand cmd = c.CreateCommand(); 
     cmd.CommandText = @"SELECT ID,NAME FROM USERS WHERE UPPER(NAME) = @NAME ORDER BY ID"; 
     cmd.Connection = c; 

     IDbDataParameter p = cmd.CreateParameter(); 
     p.ParameterName = "@NAME"; 
     p.DbType = DbType.String; 
     p.Size = 15; 
     p.Value = "test_spring"; 
     cmd.Parameters.Add(p); 

     IDataReader myreader = cmd.ExecuteReader(); 

     DataTable dt = new DataTable(); 

     int fieldCount = myreader.FieldCount; 
     for (int i = 0; i < fieldCount; i++) 
     { 
      dt.Columns.Add(myreader.GetName(i), myreader.GetFieldType(i)); 
     } 
     while (myreader.Read()) 
     { 
      object[] values = new object[fieldCount]; 
      myreader.GetValues(values); 
      DataRow dataRow = dt.Rows.Add(values); 
      // We should not AcceptChangesDuringFill to avoid multiple data row versions 
     } 

     dt.EndLoadData(); 

堆棧跟蹤：

PLZ我要完成一個項目！任何想法？？

您忘記爲IDbCommand cmd設置CommandType，並且還更改了參數化變量的名稱。

using (DbCommand cmd = c.CreateCommand()) 
    { 
     cmd.CommandText = @"SELECT ID, NAME FROM USERS WHERE UPPER(NAME) = @name ORDER BY ID"; 
     cmd.Connection = c; 
     cmd.CommandType = CommandType.Text 

     IDbDataParameter p = cmd.CreateParameter(); 
     p.ParameterName = "@name"; 
     p.DbType = DbType.String; 
     p.Size = 15; 
     p.Value = "test_spring"; 
     cmd.Parameters.Add(p); 
    }
