Hi all,

I'm new to JPQL, there is a select statement on 2 Objects.
TN object will refer to TNChar object, there relationship is 1 TN to multiple TNChars; in TN object, there is a primary key 'entityId' refer to a foreign key 'charowner' in TNChar.
If I want to search basing on the multiple TNChars to get the TN object, how I can write the JPQL.

Here is some detail about
TN.entityid = 1000 ~ TNChar.name='PREFIX' &TNChar.value='123'
~ TNChar.name='Region' &TNChar.value='Cen1'
refer to the sample, i want to base on the 2 TNChar records to get the TN.

Thanks!
Winifred
