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. To delete a column, select it in the GROUP BY Columns box and click the Left Arrow. Use the Up and Down Arrows to scroll through the columns in the GROUP BY Columns box.
Add a Computed Column
Click the Add a Computed Column button, located between the Right and Left Arrows, to open the Expression Editor and build your GROUP BY condition.
Click this button to create a CUBE operation query. CUBE adds subtotal rows into result sets of queries with GROUP BY
clauses, providing all possible combinations of the variables specified in the query.
Click this button to create a ROLLUP operation query. ROLLUP adds subtotal rows into result sets of queries with GROUP
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.
Select this option to add GROUPING SETS to a query.
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.
Click the SQL tab at the bottom of the window to see the SQL statements for your query.
You 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.
