I have tried but no luck..
FAILED: Parse Error: line 1:27 mismatched input 'as' expecting EOF near '
page_view' and took out as and tried and it gave me same syntax error as
earlier one.
FAILED: Parse Error: line 1:48 cannot recognize input near 'select' 'max' '('
in expression specification
Thanks,
Hazarath.
