I have to retrieve information from all columns of a row based on a given value. the data is fname - John lname - Andrews snumber - 008 degree - MIT I have this query that returns only the degree column: scan 'CWRK', {COLUMNS => 'STUDENT', FILTER => "ValueFilter ( =, 'binaryprefix:MIT')"} this gives the result: student:008 column=STUDENT:degree, timestamp = ......... , value=MIT I want to run a query that returns values for all 4 attributes (fname, lname, snumber, degree) for the row-number student:008 as that is the row that has the MIT value for degree key. Can this be done?
