Suppose you have the following:

Code:

Date lDate = new Date();
Query lQuery = lSession.createQuery("from table a where a.time < :pTime");
lQuery.setParameter("pTime", lDate);

What is difference between this code using setTime...

Code:

Date lDate = new Date();
Query lQuery = lSession.createQuery("from table a where a.time < :pTime");
lQuery.setTime("pTime", lDate);

Looking for an actual reason instead of personal preference...

Thanks, Michael

Hi,
Here's a snippet from the hibernate javadoc for Query.setParameter

Quote:

Bind a value to a JDBC-style query parameter. The Hibernate type of the parameter is first detected via the usage/position in the query and if not sufficient secondly guessed from the class of the given object.

Looks like internally, hibernate has to do more work to determine the actual type of the object.

Using setTime() hibernate knows the type and does not need to determine it.
