I have two tables: o_daily_lcsgeneration
and o_daily_generation
.
While trying to update the o_daily_generation
I receive an error saying:
error(1111) invalid use of Group function
Here is the code I am running:
update o_daily_generation join o_daily_lcsgeneration
on o_daily_generation.Location =o_daily_lcsgeneration.Location
and o_daily_generation.Date =o_daily_lcsgeneration.Date
set o_daily_lcsgeneration.Turbine_Generation =sum(o_daily_generation.Turbine_Generation)
