import(
"database/sql"
_ "github.com/go-sql-driver/mysql"
)
func DBQuery() []map[string]string{
var db *sql.DB
var err error
db, err = sql.Open("mysql", dbServer) //dbServer is my local mysql database
str:=call user_list(); //user_list() is a procedure of mysql database,it return the list of all user
rows,err:=db.Query(str)
if err!=nil{
fmt.Println("err=",err)
}
}

where i call this function ,the error is:Error 1312: PROCEDURE mytestdb.user_list can't return a result set in the given context

this function can work on win7 64bit and centos 64bit system,but it can not work on ubuntu 14.04 64bit system
