Best Practice of a date-only query?

[Inacio]

What is the best practice to enable date-only queries?

Should I create an alternative attribute to store a String like
yyyyMMdd and control its persistence by @PrePersit / @PreUpdate?

Or is there a way to query ignoring time information of a Date
attribute?

I wanna give date queries to my users avoing timezone, performance and
scalability issues.

Thanks a lot

You should be able to use java.sql.Date.
