t1000的错误不存在

Question

我正在尝试从C#运行存储过程，我一直收到错误：

  

名称为t1000的游标不存在

这是我的SQL语法，但它看起来像光标t1000确实存在？

Select emcd 
INTO #UpdateThese
from dailylistedinformation
WHERE CAST(RescheduledDate As Date) = CAST(GETDATE() As Date)

Declare @t1000 int

DECLARE t1000 CURSOR FOR  
SELECT emcd 
FROM #UpdateThese

OPEN t1000   
FETCH NEXT FROM t1000 INTO @t1000   

WHILE @@FETCH_STATUS = 0   
BEGIN       
  DELETE FROM production
  WHERE emcd = @t1000
  INSERT INTO production (name, address, phone, email, zip, city, state)
  SELECT name, address, phone, email, zip, city, state
  from dailylistedinformation
  where CAST(RescheduledDate As Date) = CAST(GETDATE() As Date)
   FETCH NEXT FROM t1000 INTO @t1000   
END   

CLOSE t1000   
DEALLOCATE t1000

这是我的C＃我是如何调用它的，它每次都会遇到catch块并产生上述错误：

private void DoSomethingCrazy()
{
  DoSomethingCrazy();
}

public DataSet DoSomethingCrazy()
{
  _dataSet = new DataSet();  
  SqlQueryBuilder = new StringBuilder();
  SqlQueryBuilder.Append("exec dbo.runstoredprocedure ");
  _dataSet = ExecuteSqlQuery(databaseConnection, SqlQueryBuilder.ToString());
  return _dataSet;  
}

public DataSet ExecuteSqlQuery(string connectionString, string sqlQuery)
{
  try
  {              
    _connectionString = System.Configuration.ConfigurationManager.AppSettings[connectionString].ToString();     
    _sqlDatabaseConnection = new SqlConnection(_connectionString);
    _sqlCommand = new SqlCommand(sqlQuery, _sqlDatabaseConnection);
    _sqlDatabaseConnection.Open();
    _sqlCommand.CommandTimeout = 0;    
    _dataSet = new DataSet();
    _sqlDataAdapter = new SqlDataAdapter(_sqlCommand);            
    _sqlDataAdapter.Fill(_dataSet, "Data");
    return _dataSet;
  }
  catch (Exception exception) { throw exception; }
  finally
  {
    _sqlDatabaseConnection.Close();
    _sqlCommand.Dispose();
    _sqlDataAdapter.Dispose();
  }
}
