ComponentsAvailable Columns This box lists all the tables you chose for your query and the columns in each table.
GROUP BY Columns To group by a column, select a column or set of columns in the Available Columns box and click the Right Arrow button.

ROLLUP button Click this button to create a ROLLUP operation query. ROLLUP adds subtotal rows into result sets of queries with GROUP BY clauses.
Set button Click this button to create a concatenated grouping sets operation query. Like ROLLUP and CUBE, this operation adds subtotal rows into result sets of queries with GROUP BY clauses.
GROUPING SETS Select this option to add GROUPING SETS to a query.
Results Click the Results tab at the bottom of the window to see the results of your query, or an error message if the query contains errors.
SQL Click the SQL tab at the bottom of the window to see the SQL statements for your query.
About GROUP BY conditionsYou can group by columns, alias names, or functions. The result of the query contains one row for each distinct set of values in the named columns, aliases, or functions. All null-containing rows are treated as a single set. The resulting rows are often referred to as groups since there is one row in the result for each group of rows from the table list. Aggregate functions can then be applied to these groups to get meaningful results.
When GROUP BY is used, the Columns tab, HAVING tab, and ORDER BY tab must not reference any identifier that is not named in the GROUP BY tab. The exception is that the Columns tab and HAVING tab may contain aggregate functions.
