数据截断：错误的日期时间值

Question

I work in a spring project which uses mysql db. When every insert and update sql command runs in backend side of the project while the app is running in my local, i got these type exceptions for "datetime" variables;

Caused by: java.sql.BatchUpdateException: Data truncation: Incorrect datetime value: '' for column 'CREATION_DATE' at row 1 at com.mysql.jdbc.ServerPreparedStatement.executeBatch(ServerPreparedStatement.java:665) at org.hibernate.jdbc.BatchingBatcher.doExecuteBatch(BatchingBatcher.java:70) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:268) ... 54 more

Mysql version: 5.7.18, mysql-connector-java version: -5.1.38, user-timezone is"-Duser.timezone=Europe/Istanbul" in tomcat 7 vm arguments and db timezone: GMT +3

Sample code block;

        ResponseCreateTicket response = new ResponseCreateTicket();
        TicketDTO ticket=new TicketDTO();
ticket.setTicketNumber(UUID.randomUUID().toString().toUpperCase(Locale.ENGLISH));
        ticket.setStatus(TicketStatus.UNCOMPLETED.toString());
        Date date = new Date();
        ticket.setCreatedOn(date);
        ticket.setReferenceNumber(request.getReferenceNumber());
        getTicketDAO().createTicket(ticket);
        response.setTicketNumber(ticket.getTicketNumber());
        return response;

The sql hibernate showed and binded parameters;

Hibernate: insert into eis_ticket (TICKET_NUMBER, STATUS, CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE, REFERENCE_NUMBER, ID) values (?, ?, ?, ?, ?, ?, ?, ?) 2018-05-16 10:57:37 TRACE BasicBinder:? - binding parameter [1] as [VARCHAR] - 9BF25A08-C442-45FA-A95F-8E59502CE037 2018-05-16 10:57:37 TRACE BasicBinder:? - binding parameter [2] as [VARCHAR] - UNCOMPLETED 2018-05-16 10:57:37 TRACE BasicBinder:? - binding parameter [3] as [VARCHAR] - 2018-05-16 10:57:37 TRACE BasicBinder:? - binding parameter [4] as [TIMESTAMP] - Wed May 16 10:57:32 EEST 2018 2018-05-16 10:57:37 TRACE BasicBinder:? - binding parameter [5] as [VARCHAR] - 2018-05-16 10:57:37 TRACE BasicBinder:? - binding parameter [6] as [TIMESTAMP] - 2018-05-16 10:57:37 TRACE BasicBinder:? - binding parameter [7] as [VARCHAR] - b4be9b87-21c4-4001-b80d-244420ab2e00 2018-05-16 10:57:37 TRACE BasicBinder:? - binding parameter [8] as [BIGINT] - 1925 2018-05-16 10:57:37 ERROR JDBCExceptionReporter:? - Data truncation: Incorrect datetime value: '' for column 'CREATION_DATE' at row 1

The date format can be change to "yyyy-MM-dd HH:mm:ss" but there is hundreds of these types codes in project so it will not be the right solution. What could be causing this problem? Mysql connector is updated but not worked.

Answer 1

If the column type is date-time, you can easily modify the column and set the default to CURRENT_TIMESTAMP , this will ensure that every record inserted will default to the current server date and time. However if you are generating the timestamp manually, then the data type generated on the app, is not similar to the data type used when inserting in the database You can use this to modify the column default, then leave the creation_type column NULL when inserting a record.

ALTER TABLE table MODIFY CREATION_DATE TIMESTAMP DEFAULT CURRENT_TIMESTAMP NOT NULL;
