We have an entity column with a formula property that requires today’s date at midnight in order to calculate itself property:

DATEADD(DD, DATEDIFF(DD, 0, GETDATE()), 0)

Hibernate transforms this into:

DATEADD(mytablename0_.DD, DATEDIFF(mytablename0_.DD, 0, GETDATE()), 0)

I’ve double checked that my dialect is SqlServer. I’ve also replaced DD with DAY, but the problem remains.

How do I get hibernate to recognize that DD is a keyword?

    I had the same issue when upgrading from Sybase to SQLServer. The field in my scenario was an integer field used to store a date since 1970-01-01. The DATEADD function was used to convert that integer into a genuine date so we had a good representation through the hibernate mapped objects.

    My original mapping for this field was the following:

    <property name="lostDate" type="date">
  <formula>dateadd(dd, lost_date, '01-JAN-1970')</formula>
</property>

    This resulted in the problem that you described in the question, where the resulting sql passed to the database was: 

    dateadd( table0_.dd, table0_.lost_date, '01-JAN-1970')

    Updating the mapping to surround the dateadd keyword dd in double quotes resolved this issue for me.

    <property name="lostDate" type="date">
  <formula>dateadd("dd", lost_date, '01-JAN-1970')</formula>
</property>

    SQL Server 2008 accepted the generated SQL below and executed as expected.

    dateadd("dd", table0_.lost_date, '01-JAN-1970')
