Is it possible to write 1 select statement in VFP that will return the frequency of items across two tables. For Instance I have two separate tables that contain information about the use of a product. I want to see the total frequency of each item across the tables

Table 1
Item RespondentId SurveyId
Item 1 1 1
Item 1 2 1
Item 1 3 1
Item 2 1 1


Table 2
Item RespondentId SurveyId
Item 1 1 2
Item 2 2 2
Item 1 3 2
Item 2 1 2

I would like 1 select statement that returns

Item Freq
Item 1 5
Item 2 3


Is this possible in VFP without appending the two tables first?

Thanks for the help.
