My another question is about using OO-features of QueryBuilder with pre-defined DB-connection.
I know, that I can set "read connection" in the model depending on query parameters, but it is not the way I plan to produce queries to databases. My way is: 1. Choose DB-connection (choose right database-source) 2. Prepare query to choosen database with Query Builder 3. Execute PHQL-query
Is it real?
