Use the Criteria pane to enter your HAVING conditions. You can type directly into this pane, or use the Expression Editor. To edit existing
expressions, highlight the expression before you open the Expression Editor. Otherwise, what you create in the Expression
Editor is appended to previously existing expressions.

HAVING conditions can only be used if either the statement has a GROUP BY clause or the selected columns in the Columns tab include only aggregate functions. Any column names referenced in the HAVING clause must either be in the GROUP BY clause
or be used as a parameter to an aggregate function in the HAVING clause.
