    The query will take a few moments to return results. When the query completes, the results are displayed below the project name. The query results are listed in two columns, corresponding to the two expressions in the ``select`` clause of the query. The first column corresponds to the expression ``ifstmt`` and is linked to the location in the source code of the project where ``ifstmt`` occurs. The second column is the alert message.
