sqlx返回空结构，即使它存在

Here is my code :

package main

import (
    "fmt"
    "github.com/jmoiron/sqlx"
    _ "github.com/lib/pq"
    "log"
    "time"
)

type Commune struct {
    Id int `db:"id"`
    Created time.Time `db:"created"`
    Modified time.Time `db:"modified"`
    Name string `db:"name"`
}

func main() {
    var err error
    db, err = sqlx.Connect("postgres", "user=toto 
    dbname=tata password=titi sslmode=disable")
    commune := []Commune{}
    db.Select(&commune, `SELECT * FROM "Geo_commune"  WHERE id=1  ORDER BY name ASC`)
    rows, err2 := db.Query(`SELECT * FROM "Geo_commune"  WHERE id=1  ORDER BY name ASC`)
    fmt.Println(commune)
    fmt.Println(rows)
    if err != nil {
    log.Fatalln(err)
    }
     if err2 != nil {
    log.Fatalln(err2)
    }

   }

here is the data in the database :

edit : the table_name :

and i've even tried with :

db.Select(&commune, `SELECT * FROM "Geo_commune"  WHERE id=1  ORDER BY name ASC`)

but the return is always empty and i'am sure that the data exists and i don't have a connection error.

Without the "Geo_commune" rows, err2 := db.Query(SELECT * FROM Geo_commune WHERE id=1 ORDER BY name ASC) i have a : 2019/01/28 22:17:16 pq: relation "geo_commune" does not exist

edit my new tests :

package main

import (
    "fmt"
    "github.com/jmoiron/sqlx"
    "log"
    "time"
    _ "github.com/lib/pq"
)
type Commune struct {
    Id int `db:"id"`
    Created time.Time `db:"created"`
    Modified time.Time `db:"modified"`
    Name string `db:"name"`

}
var db *sqlx.DB
func main() {
    var err error
    db, err = sqlx.Connect("postgres", "user=toto dbname=titi password=tata sslmode=disable")
    commune := []Commune{}

    if err != nil {
        log.Fatalln(err)
    }
    db.Select(&commune, `SELECT * FROM "Geo_commune"  WHERE id=1  ORDER BY name ASC`)
    rows, err2 := db.Query(`SELECT * FROM "Geo_commune"  WHERE id=1  ORDER BY name ASC`)
    if err != nil {
        log.Fatalln(err)
    }
    if err2 != nil {
        log.Fatalln(err2)
    }


    db.Select(&commune, `SELECT * FROM public.Geo_commune  WHERE id=1  ORDER BY name ASC`)
    rows, err2 = db.Query(`SELECT * FROM public.Geo_commune  WHERE id=1  ORDER BY name ASC`)
    fmt.Println(commune)
    fmt.Println(rows)
    if err != nil {
        log.Fatalln(err)
    }
    if err2 != nil {
        log.Fatalln(err2)
    }



    }

gives me :

[]
<nil>
2019/01/29 09:50:06 pq: relation "public.geo_commune" does not exist

I'm confused with your description. did it throw pq: relation "geo_commune" does not exist? if it did, your datasource is incorrect. if it didn't, try select * from public.Geo_commune
