Cannot convert '0000-00-00 00:00:00' to TIMESTAMP

Question

the field definition

 /** Date. */
  @Column(columnDefinition = "datetime")
  private Date date;

setter

public void setDate(final Date date) {
    DateFormat dfmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    try {
      this.date = dfmt.parse(dfmt.format(date));
    } catch (ParseException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }

  }

Does anyone have idea how to convert "zero date" into proper value ? Because i have error:

Cannot convert value '0000-00-00 00:00:00' from column 13 to TIMESTAMP

And even if i set "default" field and setter like this:

/** Date. */
      @Column
      private Date date;


public void setDate(final Date date) {
      this.date = date;   
  }

I'll still have the same problem....

Answer 1

I'm going to take a wild guess here that you're using MySQL :-) It uses "zero dates" as special placeholder - unfortunatelly, JDBC can not handle them by default.

The solution is to specify "zeroDateTimeBehavior=convertToNull" as parameter to your MySQL connection (either in datasource URL or as an additional property), e.g.:

jdbc:mysql://localhost/myDatabase?zeroDateTimeBehavior=convertToNull

This will cause all such values to be retrieved as NULLs.
