    Hi Expert,

    I use the code to fetch the oracle sample data as below:

    using (OracleConnection _connection = new OracleConnection(_oradbConnectionString))
                {
                    _connection.Open();
                    OracleCommand _cmd = new OracleCommand();
                    _cmd.Connection = _connection;
                    _cmd.CommandText = _oradbSelectStatement +
                        " where OUT_JOB between TO_DATE('" + _beginDate + "', 'MM/DD/YYYY') and TO_DATE('" + _endDate + "', 'MM/DD/YYYY')";
                    _cmd.CommandType = System.Data.CommandType.Text;

                    using (OracleDataReader _reader = _cmd.ExecuteReader())
                    {
                        if (_reader.HasRows)
                        {
                            while (_reader.Read())
                            {
                                ListItemCollection _sPListItemCollection = GetItemsCol(args[0], _reader.GetString(0).ToString());

    But I perform the code again and again every time I got the same value of the date ... even I change the value from oracle ... 

    I don't know why??

    Perhaps there is an issue in the WHERE condition, you should never use string concatenation but instead use parameters. See the second code block in this code sample.

    Hello will,

    Your description is related third party products, I am afraid that the issue is out of support of C# General Question forum which mainly discusses C# programming language, IDE, libraries, samples and tools.

    I suggest that you can consult your issue directly on Oracle forum for better solution and support.

    If I have misunderstood anything, please feel free to let me know.

    Best regards,

    Neil Hu
