Mysql insert into with select distinct

QUESTION

Mysql insert into with select distinct

Asked 2017-Jun-22 at 05:45

i'm using java with mysql,i have this code in mysql

SELECT DISTINCT date(datecreat) as datetemp , (SELECT max(sensortemp) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as maxt , (SELECT min(sensortemp) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as mint , (SELECT avg(sensortemp) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as avgt , (SELECT max(sensorhum) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as maxh , (SELECT min(sensorhum) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as minh , (SELECT avg(sensorhum) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as avgh , (SELECT max(sensorpres) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as maxp , (SELECT min(sensorpres) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as minp , (SELECT avg(sensorpres) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) as avgp FROM akdb.iotdatas where (serialnum ='0000000000000');

the result is like this:

but i want to insert this data into other table using this code

insert into akdb.climdatas(hightemp,lowtemp,avgtemp,highhum,lowhum,avghum,highpress,lowpress,avgpress,dateinsert,zonedatas)values(maxt,mint,avgt,maxh,minh,avgh,maxp,minp,avgp,datetemp,'zone h');

here the problem is "maxt mint ..." are unknown, but if i use select into insert

insert into akdb.climdatas(SELECT DISTINCT date(datecreat) as datetemp ,(SELECT max(sensortemp) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) , (SELECT min(sensortemp) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) , (SELECT avg(sensortemp) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) , (SELECT max(sensorhum) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) , (SELECT min(sensorhum) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) , (SELECT avg(sensorhum) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) , (SELECT max(sensorpres) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) , (SELECT min(sensorpres) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ) , (SELECT avg(sensorpres) FROM akdb.iotdatas WHERE date(datecreat)=datetemp ),' zone h'FROM akdb.iotdatas where (serialnum ='0000000000000000'))

the error is in the columns "mysql column count doesn't match value count at row 1"

Seems like you have more or less than 11 columns in climdatas table. In your insert statement, specify list of columns separated by comma.
