The document screen holds a query and result sets associated with it.
The document toolbar provides access to the most commonly used functions for a query.
The query tab is used to write the SQL query.
At any stage you can pop up a list of the tables on this database by pressing CTRL+T in the SQL tab
You can pop up a list of fields in the current table by pressing CTRL+L in the SQL window with the cursor placed after the table name of the table concerned. The field list is automatically popped up when you press the dot after a table name.
Where you have more than one query to execute they must be explicitly separated by go.
The results tab shows the records returned by the last query. The field names are in the top row and the data is in each subsequent row. Where multiple queries are executed in one go they will each get one results tab, in the order they are executed.
