My question is there is an error in every insert

回答1:

This expression 12-4-2005 is a calculated int and the value is -1997. You should do like this instead '2005-04-12' with the ' before and after.

回答2:

Try wrapping your dates in single quotes, like this:

'15-6-2005'

It should be able to parse the date this way.

回答3:

FYI this turned out to be an issue for me where I had two tables in a statement like the following:

SELECT * FROM table1
UNION ALL
SELECT * FROM table2

It worked, but then somewhere along the line the order of columns in one of the table definitions got changed. Changing the * to SELECT column1, column2 fixed the issue. No idea how that happened, but lesson learned!

回答4:

I had the same problem. I tried 'yyyy-mm-dd' format i.e. '2013-26-11' and got rid of this problem...

回答5:

I have this problem and in my case the date is wrapped with ' (single quote)... the thing is in my case the insert statement is created by Hibernate so nothing is wrong with it... we have a lot of other dates in the same table and all work fine except this particular date column. It's frustrating and the only way to fix it is to pass null for that column... any idea??

insert into member_account (pension_nextdue_date, pension_nextrun_date, first_payment_date, fund_start_date, pension_escalation_percent) values (null, null, '2014-04-28', '2014-02-02', 12)

I removed other columns from the insert statement above to make it small... the pension_payment_date causes the issue...

I checked the column type and table everything is correct and the type of this date is not different than the others in the same table.
