Now all datatype use same method ` stmt.setString(index,value);` even DATE and TIMESTAMP.
So i had improved it. If datatype is DATE use `stmt.setDate(index, java.sql.Date.valueOf(value));` , if datatype is TIMESTAMP use `stmt.setTimestamp(index, java.sql.Timestamp.valueOf(value));`.i
When use DATE the param format must use $[yyyy-MM-dd] , When use TIMESTAMP the param format must use $[yyyy-MM-dd hh:mm:ss].
