hi Lefteris,

Thanks For help me...

MonetDB version that we are using is: MonetDB v11.15.11

This is the Schema of my table:::

create table enzensubstation_hour(
edate date,
eHour int,
ss_id varchar(50),
loc_id varchar(50),
tot_active_power_h decimal(5,4),
phase_differ_voltage_h decimal(8,6),
stn_bat_voltage_h decimal(8,5)
);

insert into enzensubstation_hour
SELECT
edate,
CAST(SUBSTRING(etime,0,2) AS int) AS eHour,
ss_id,
loc_id,
avg(tot_active_power) as tot_active_power_h,
avg(phase_differ_voltage) as phase_differ_voltage_h,
avg(stn_bat_voltage) as stn_bat_voltage_h
FROM enzensubstation
group by
edate,
ehour,
ss_id,
loc_id
;

Thanks

Hi Ketan,

This does not sound right.

could you please tell us which MonetDB version are you using, also
could you give us the complete query, as well as the output of running
the query prefixed with "explain" ?

Also can you tell us the schema of the table and if you have any
constraints on it, such as primary key?

thank you,

lefteris
