Hi all.

I have some problem with getting data from external source (PostgreSQL) via JDBC and load it in DeepSee and I resolved some problems while writing this question :)

So..Below I proved my steps of working:

1. Created SQL Gateway Connection
2. Created class for loading data via JDBC
   

   S Connection=##class

   1. In 2 line I got exception (not saved it) and I exclusive this option
3. Next I Created projections via SQL wizard and now all tables stored in Cache and I get needed data via  ##class(%ResultSet.SQL).%Prepare()
4. After that I create model (StudentRating) in sequence by result set
