Incorrect translation for "SELECT mgr_start_date FROM department d WHERE dname = 'Research'"

[wholton]

Query: SELECT mgr_start_date FROM department d WHERE dname = 'Research'

Translation: Select the start date of the Research department.

Perhaps we should change the label to "start date of the manager" or "department's manager's start date" ? Both are a bit awkward. Maybe we'll need to find some tag for this type of attribute.
