Is there a pivot/transform function available? I need to pivot the rows to columns without the knowledge of the values.
~~~~~~~~~~~~ Source table: date | page | count 20150301 | p1 | 10 20150301 | p2 | 20 ... Result table that I would like without the knowledge of the distinct values for 'page' column: date | p1_count | p2_count | ....so on 20150301 | 10 | 20 | ... ~~~~~~~~~~~~~ Thanks!
