We can query more than one table (all tables need to be registered). Tables
should be registered at the TableEnvironment. I think the term `tables
registry` is not defined.

> Project: Flink
> Issue Type: New Feature
> Components: Table API
> Affects Versions: 1.1.0
> Reporter: Vasia Kalavri
> Assignee: Vasia Kalavri
>
> This issue covers the task of supporting SQL queries embedded in DataSet
> programs. In this mode, the input and output of a SQL query is a Table. For
> this issue, we need to make the following additions to the Table API:
> - add a {{tEnv.sql(query: String): Table}} method for converting a query
> result into a Table
> - integrate Calcite's SQL parser into the batch Table API translation process.
