# java-cli-buildr-hibernate-sqlserver-case-count
2+
3+
## Description
4+
Creates a small database table
5+
called `dog` and populates with
6+
hql. Creates 2 lookup tables `breedLookup`
7+
and `colorLookup` and 4N `dog`.
8+
9+
Joins `breedLookup` and `colorLookup`
10+
to form a new table `dogextended`. These
11+
case-counts are deministrated 3 ways, `ResultTransformer`,
12+
looking up ids on `breedLookup` and `colorLookup`,
13+
and non-ResultTransformer method.
14+
15+
Add an immutable entity `breedcount` as a case-count uses a subquery join.
16+
17+
Updated an immutable entity `breedcount` as a view using a subselect with
18+
case and join.
