    I have mentioned code below, there is connection for ms access to get date & need to assign in array for insertion in oracle, but after its successful compilation then i will make connection to insert data in oracle database by the array.

    I have added parameter for EMPNO but i need to add date parameter, actually I have to get data on the base of date parameter.

    So kindly please if it possible to add data parameter in query as well.

    Tanks for helping me
