我已经搜索了这个错误并找到了两个问题:
这是我的代码:
package main
import (
"log"
"github.com/jmoiron/sqlx"
_ "github.com/lib/pq"
)
var schema = `
CREATE TABLE films (
code int,
name VARCHAR(10)
)`
type Film struct {
code int
name string
}
func main() {
db, err := sqlx.Open("postgres", "user=demas password=root host=192.168.99.100 port=32768 dbname=mydb sslmode=disable")
if err != nil {
log.Fatal(err)
}
db.MustExec(schema)
tx := db.MustBegin()
tx.MustExec("INSERT INTO films(code, name) VALUES($1, $2)", 10, "one")
tx.MustExec("INSERT INTO films(code, name) VALUES($1, $2)", 20, "two")
tx.Commit()
films := []Film{}
err = db.Select(&films, "SELECT * FROM public.films")
if err != nil {
log.Fatal(err)
}
}
它创建了一张表,插入了两条记录,但无法将它们返回:
λ go run main.go
2016/09/26 14:46:04 non-struct dest type struct with >1 columns (2)
exit status 1
我该如何修复它?
