Question

问题是：我在PostgreSQL中有一个数据库，我读取Golang中的所有数据并从中创建数组。问题是：如何将这个数组放入Influxdb？

Answer 1

package main

import (
"database/sql"
"log"
_ "./pq"
"fmt"

)

type DbInfo struct {
id string
person_id int
timestamp int
age string
gender string
attention string
interest int
happines int
surprise int
anger int
disgust int
fear string
sadness int
neutrall string

}

var DBObject DbInfo
var DbArray []DbInfo




func main() {


db, err := sql.Open("****", "postgres://postgres:********/cam?
sslmode=disable")
if err != nil {
    log.Fatal(err)
}
defer db.Close()
rows, err := db.Query(`SELECT avg(age), avg(id), avg(neutrall),avg(fear)  
 FROM public.stat`) //stringTimeDayAgoQuery )
if err != nil {
    log.Fatal(err)
}
defer rows.Close()
for rows.Next() {
    //err := rows.Scan(&DBObject.id, &DBObject.person_id, 
 &DBObject.timestamp,&DBObject.age, 
 &DBObject.gender,&DBObject.attention,&DBObject.interest,&DBObject.happines, 

   &DBObject.surprise,&DBObject.anger,&DBObject.disgust,&DBObject.fear, 
   &DBObject.sadness,&DBObject.neutrall)
    err := rows.Scan(&DBObject.age,&DBObject.id,&DBObject.neutrall, 
   &DBObject.fear)

    if err != nil {
        log.Fatal(err)
    }
    DbArray = append(DbArray, DBObject)
}
fmt.Println(DbArray)

} 在这段代码中。我从postgreSQL读取数据。我把它读作数组，现在我想将输出导入Influxdb。因为我想使用Grafana，它不适用于postgresql。

如何将数据从golang数组转移到Influxdb？
