MySQL has the following functions to get the current date and time: SELECT. Now we need to serviceMethod() which is responsible for the getting request for desired result.then after need to load all the drivers as required procedure.Now we need to declare the variables like Connection(this variable does the role of interaction between frontEnd and backEnd in other words it will make connection between database and actual code of java).resultset which will produce table of data from its own object.preparedStatement this variable will use to execute the Query like executeQuery().preparedStatement will execute below query (SELECT name FROM worker WHERE name LIKE ‘R%’).And after that the doGet() will have to use for fetching result on a web Browser. then we need to declared a class named ‘JavaServletLikeQuery’ which is been extends ‘HttpServlet’.
