Hello, I want to compute difference between successive records. In MySQL, I had written something like :
SET @prev := 0; SELECT time_to_sec(@prev), @prev := ts FROM mytable; How to achieve the same with sqlalchemy ? (I prefer to do it in SQL rather than python because I want to aggregate the results) Best regards -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
