You can insert time values in SQL using the time datatype, The java.sql.Time class maps to the SQL Time type.The PreparedStatement interface provides a method named setTime(). Using this you can insert time into a table. This method accepts two parameters −An integer representing the parameter index of the place holder (?) to which we need to set date value.A Time object representing the time value to be passed. The constructor of java.sql.Time class accepts a variable of long type representing the number of milliseconds from the epoch (standard base time I.e. January 1, 1970, 00:00:00 GMT).ExampleAssume we have created ... Read More

The ResultSet interface provides a method named getDate() this method accepts an integer parameter representing the index of the column, (or, a String parameter representing the name of the column) from which you need to retrieve the date value. To retrieve date value from a table −Register the driver class using the registerDriver() method of the DriverManager class. Pass the driver class name to it, as parameter.Connect to the database using the getConnection() method of the DriverManager class. Passing URL (String), username (String), password (String) as parameters to it.Create a Statement object using the createStatement() method of the Connection interface.Execute ... Read More
