Question

I’m writing an integration test in Grails using GORM.

I want to do something like the following:

delete from Statistic 
where stat_date = TO_DATE(:month_year, 'MON-YYYY')

But I get the following error:

java.sql.SQLException: Unexpected token: TO_DATE in statement [delete
from statistics where stat_date=TO_DATE(?, ‘MON-YYYY’)]

I think the error is caused by the in memory database used by GORM (is it H2?) not supporting the to_date function.

Any ideas on how to write the delete SQL so that it works in a test and in live?

As I only really care about the Month and Year one thought I had would be to delete the records where the stat_date is between the first and last date of the given month.

Can any one think of a better way?

Answer 1

Yes, H2 doesn’t support TO_DATE, it’s in 1.4.x roadmap. Instead you can use the EXTRACT function that exists both in Oracle DB and H2.
