      Adds the phoenix.query.applyTimeZoneDisplacement attribute, which enables applying timezone displacement when setting or retriteving java.sql. time types via PreparedSatetement and ResultSet objects.

      Setting the attribute will result in interpreting the epoch-based java.sql time types in the local timezone.

      This attribute is off by default for backwards compatibility reasons, and needs to be enabled explicitly. This is a client side attribute, and can be set on a per connection basis.

    Description

      We have two methods to write data when uses JDBC API.
      #1. Uses the exceuteUpdate method to execute a string that is an upsert SQL.
      #2. Uses the prepareStatement method to set some objects and execute.

      The string data needs to convert to a new object by the schema information of tables. we'll use some date formatters to convert string data to object for Date/Time/Timestamp types when writes data and the formatters are used when reads data as well.

       

      Uses default timezone test

       Writing 3 records by the different ways.

      UPSERT INTO date_test VALUES (1,'2018-12-10 15:40:47','2018-12-10 15:40:47','2018-12-10 15:40:47') 
      UPSERT INTO date_test VALUES (2,to_date('2018-12-10 15:40:47'),to_time('2018-12-10 15:40:47'),to_timestamp('2018-12-10 15:40:47'))
      stmt.setInt(1, 3);stmt.setDate(2, date);stmt.setTime(3, time);stmt.setTimestamp(4, ts);

      We have a historical problem,  we'll parse the string to Date/Time/Timestamp objects with timezone in #1, which means the actual data is going to be changed when stored in HBase table。
