iReport中的错误日期损坏了Jasper服务器报告

Question

I am getting null dates in iReport and some dates with 0000-00-00 and some with invalid dates. Aside from changing the database itself I need to be able to clear them or something. I was thinking of handling this on the SQL side of things, opinions or solutions welcome.

Answer 1

Here is one way of accomplishing this on the SQL side:

IF(yourtable.yourdatefield < '1970-01-01',
CAST(yourtable.yourdatefield AS CHAR(10)),yourtable.yourdatefield) AS yourdatefield
