Then I want to retrieve data by PR. Here is my interface to insert search detailsenter image description here

Date choose from date JDateChooser. I used LIKE clause to get data from the db, but it does not work. Here is the MYSQL query statement.

        String prlQuery = "SELECT * FROM final_report WHERE used_PR LIKE '?%' OR create_PR LIKE '?%'";

        try {
            Date chooseDate = new Date(dateChooser.getDate().getTime());
            String parameter = "PR-L-" + selectMachine.getSelectedItem() + "-" + chooseDate;

            pst = connect.dbConnection().prepareStatement(prlQuery);
            pst.setString(1, parameter);
            pst.setString(2, parameter);

But seems it is not working. Can somebody help me with this code structure.

Solution

  • You must pass the % in the parameters your query must look like 

     String prlQuery = "SELECT * FROM final_report WHERE used_PR LIKE ? OR create_PR LIKE ?";

    try {
        Date chooseDate = new Date(dateChooser.getDate().getTime());
        String parameter = "PR-L-" + selectMachine.getSelectedItem() + "-" + chooseDate;

        pst = connect.dbConnection().prepareStatement(prlQuery);
        pst.setString(1, parameter+"%");
        pst.setString(2, parameter+"%");
