I'm using a query to pull data from a multi-sheets in Google Spreadsheet that is populated by a Google Form. If the form has only numbers, there is no problem. However, if there's a mixed of text and number then it did not work.
=QUERY({Sheet1!A:S;Sheet2!A:S},"SELECT* WHERE Col4<>''",0)
EDIT: Added the second one here:
=QUERY(Sheet2!A:S,"SELECT A,C,D,E,F,G,H,I,J,K,L,R WHERE G IS NOT NULL ORDER BY G LABEL R 'FRUIT'",TRUE)
Regards,
