This component helps you create and modify a query (an SQL SELECT statement). You can manipulate the query visually or by directly changing the SQL. Once the query has been completed you can test the query and see the results.
The task of creating a query can be split into several parts. To quickly understand how to perform those parts in this tool you can skip right to the "One minute tour" for creating a simple SQL Select statement.
