Question

I’m trying to query a .NET DateTime property and compare it with a date string like so:

SELECT cat FROM mydll.cats AS cat
WHERE cat.BirthDay > '1999-02-20'

When I’m trying to search by a date string (without the SetDate function)
The query won’t run saying I canno’t compare a String to a Date.

Is there a way or a certain format I can use to compare my date with a simple string
(Maybe something like the ToDate function in Oracle SQL..)
*I need to separate the HQL string from the NHibernate engine because of design issues

Thanks a lot [=

Answer 1

The to_date function is mapped in the Oracle dialect, so:

SELECT cat FROM mydll.cats AS cat
WHERE cat.BirthDay > to_date('1999-02-20', 'yyyy-mm-dd')
