This box lists all the tables you chose for your query, and the columns in each table. It also lists any computed columns
that you defined in the Columns tab.
ORDER BY columns
This box stores the columns you chose to sort on. To sort on 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 ORDER BY Columns box and click the Left Arrow. Use the Up and Down Arrows to specify the order of column evaluation. You can sort on column
Add a Computed Column
Click the Add a Computed Column icon, located between the Right (Add the selected column to the list) and Left (Remove the selected column from the list) Arrows, to open the Expression Editor and build your ORDER BY condition.
Click Results at the bottom of the window to see the results of your query, or an error message if the query contains errors.
Click SQL at the bottom of the window to see the SQL statements for your query.
Each item in the ORDER BY column can be labeled as an Up Arrow for ascending order (the default) or a Down Arrow for descending order. To change the
order from ascending to descending, click the Arrow.
The only way to ensure that rows are returned in a particular order is to use ORDER BY. In the absence of an ORDER BY clause,
SQL Anywhere returns rows in whatever order is most efficient. This means that the appearance of result sets may vary depending
on when you last accessed the row and other factors.
