Hi Sir, I'm try to use Parameter but got this error :

Failed to convert parameter value from a String to a DateTime.

My coding like this :

 oracmd.CommandText = " INSERT INTO ASIS.TIMECLOCK\_DATE(TD\_CARDHOLDER\_ID,TD\_EVENT\_DATE,TD\_FIRST\_IN,TD\_IN\_READER,TD\_IP\_CONTROLLER,TD\_TYPE) " & \_
                                " VALUES (@CARDHOLDERID,(@EVENTDATE),(@FIRSTIN),@READER,@IP,@TYPE)"



            oracmd.Parameters.Add("@CARDHOLDERID", OracleType.VarChar).Value = "" & IBSSDR.Item("ID") & ""
            oracmd.Parameters.Add("@EVENTDATE", OracleType.DateTime).Value = "TO\_DATE('06/10/2020 09:30:00','dd/mm/yyyy hh:mi:ss am')"
            oracmd.Parameters.Add("@FIRSTIN", OracleType.DateTime).Value = "TO\_DATE('06/10/2020 09:30:00','dd/mm/yyyy hh:mi:ss am')"
            oracmd.Parameters.Add("@READER", OracleType.VarChar).Value = "" & IBSSDR.Item("DEVICE\_ID") & ""
            oracmd.Parameters.Add("@TYPE", OracleType.VarChar).Value = "CHECKIN"

      

            oracmd.CommandType = CommandType.Text

My oracle using format like this : dd/mm/yyyy hh:mi:ss am'

anyone got idea to hlep me?..Plzz

Why are you converting all of your parameter values to strings? Use the appropriate .NET type instead:

oracmd.CommandText = " INSERT INTO ASIS.TIMECLOCK_DATE(TD_CARDHOLDER_ID,TD_EVENT_DATE,TD_FIRST_IN,TD_IN_READER,TD_IP_CONTROLLER,TD_TYPE) " & _
" VALUES (@CARDHOLDERID, @EVENTDATE, @FIRSTIN, @READER, @IP, @TYPE)"

oracmd.Parameters.Add("@CARDHOLDERID", OracleType.VarChar).Value = IBSSDR.Item("ID")
oracmd.Parameters.Add("@EVENTDATE", OracleType.DateTime).Value = New DateTime(2020, 10, 6, 9, 30, 0)
oracmd.Parameters.Add("@FIRSTIN", OracleType.DateTime).Value = New DateTime(2020, 10, 6, 9, 30, 0)
oracmd.Parameters.Add("@READER", OracleType.VarChar).Value = IBSSDR.Item("DEVICE_ID")
oracmd.Parameters.Add("@TYPE", OracleType.VarChar).Value = "CHECKIN"

DateTime values do not have a format while stored in the database. The format is only applied when the value is displayed, either by the query tool you're using to test the query or by your own application. There is no format when stored by the database and that's what's tripping you up.

Sir, The datetime value is taking form another database (Firebird) using Datareader(IBSDDR.item("")), so i don't need to convert to_date when insert into ORacle sir?...Plz guide me, thanks in advanced :)

Hi Sir When i'm using Parameter got this error :-

ORA-01008: not all variables bound

Can u advise me what wrong..

oracmd.CommandText = " INSERT INTO ASIS.TIMECLOCK_DATE(TD_CARDHOLDER_ID,TD_EVENT_DATE,TD_FIRST_IN,TD_IN_READER,TD_IP_CONTROLLER,TD_TYPE) " & _
" VALUES (:CARDHOLDERID,to_date(:EVENTDATE,'dd/mm/yyyy hh:mi:ss am'),to_date(:FIRSTIN,'dd/mm/yyyy hh:mi:ss am'),:READER,:IP,:TYPE)"

oracmd.Parameters.Add(":CARDHOLDERID", OracleType.VarChar).Value = "" & IBSSDR.Item("ID") & ""
oracmd.Parameters.Add(":EVENTDATE", OracleType.DateTime).Value = ("" & IBSSDR.Item("EVENT_DATE").ToString & "")
oracmd.Parameters.Add(":FIRSTIN", OracleType.DateTime).Value = ("" & IBSSDR.Item("EVENT_DATE").ToString & "")

            oracmd.Parameters.Add(":READER", OracleType.VarChar).Value = "" & IBSSDR.Item("DEVICE\_ID") & ""
            oracmd.Parameters.Add(":TYPE", OracleType.VarChar).Value = "CHECKIN"

      

            oracmd.CommandType = CommandType.Text

...thank you

You're trying to convert date strings being passed to the parameters to date values in the SQL VALUES clause. Don't do that because all you have to do is pass in DateTime values WITHOUT using "to_date" in the SQL. And what's with the "" & garbage? Get rid of stuff. It's useless, unless you want to make the code harder to read and debug.

oracmd.CommandText = " INSERT INTO ASIS.TIMECLOCK_DATE(TD_CARDHOLDER_ID,TD_EVENT_DATE,TD_FIRST_IN,TD_IN_READER,TD_IP_CONTROLLER,TD_TYPE) " & _
" VALUES (:CARDHOLDERID, :EVENTDATE, :FIRSTIN, :READER, :IP, :TYPE)"

oracmd.Parameters.Add(":CARDHOLDERID", OracleType.VarChar).Value = IBSSDR.Item("ID") oracmd.Parameters.Add(":EVENTDATE", OracleType.DateTime).Value = IBSSDR.Item("EVENT_DATE")
oracmd.Parameters.Add(":FIRSTIN", OracleType.DateTime).Value = IBSSDR.Item("EVENT_DATE")
oracmd.Parameters.Add(":READER", OracleType.VarChar).Value = IBSSDR.Item("DEVICE_ID")
oracmd.Parameters.Add(":TYPE", OracleType.VarChar).Value = "CHECKIN"

Where is the

oracmd.Parameters.Add(":IP", ...)

:confused:

OK, one last time. THERE IS NO SUCH THING AS A FORMAT FOR A DATETIME VALUE IN A DATABASE. ALWAYS use parameters to pass values into a query string. NEVER use string concatenation to build SQL queries.
