That is because conv is only defined for numeric inputs. If you want to find the convolution symbolically, you'll have to input the equation yourself symbolically using integration.

sum(tot_hours) OVER (PARTITION BY empid ORDER BY empid ) AS tot_hours Your ORDER BY is incorrect. If you want the running SUM on the TOT_HOURS, then you should order by tot_hours. For example, the below query will calculate the running sum of salary of employees in each department: SQL>...

Group by is implying distinct values based on subscription.id so probably if you take the group by you you will get something like 8,8,8,8,8,7,7,7,7,7 due to the joins and such. With the group by you only get the distinct values of 8 and 7. When you do sum with the...
