英文:
Wrong characters On GO witn UBUNTU 12.04 and Oracle
问题
我已经设置了一个带有Ubuntu 12.04 LTS（64位）、Go 1.2.2和go-oci8（github.com/mattn/go-oci8）的机器，但是当我在Oracle 11G数据库上执行查询时，返回的俄语和中文字符是错误的。
我尝试在我的项目中设置NLS_LANG字段，如下所示：
os.Setenv("NLS_LANG", "SIMPLIFIED CHINESE_CHINA.AL32UTF8")
os.Setenv("NLS_LANG", "AMERICAN_AMERICA.AL32UTF8")
os.Setenv("NLS_LANG", "RUSSIAN_CIS.AL32UTF8")
有人可以帮助我吗？我应该设置什么样的NLS_LANG配置才能获得正确的俄语、中文或其他与英语和西班牙语不同的语言的字符？
这是一个示例：
创建表room
{
name_spainish varchar2(100),
name_chinesses varchar2(100),
name_russian varchar2(100)
}
insert into room (name_spainish, name_chinesses, name_russian) values ('Habitación doble','雙人房','двухместный номер')
package main
import (
"database/sql"
"fmt"
"os"
_ "github.com/mattn/go-oci8"
)
func main() {
ExecQuery("select name_spainish, name_chinesses, name_russian from room")
}
func ExecQuery(query string){
os.Setenv("NLS_LANG", "AMERICAN_AMERICA.AL32UTF8")
db, err := sql.Open("oci8", "user/userps@host:1521/SID")
if err != nil {
fmt.Println(err)
return
}
rows, err := db.Query(query)
if err != nil {
fmt.Println(err)
return
}
for rows.Next() {
var nameSpainish string
var nameChinesses string
var nameRussian string
rows.Scan(&nameSpainish, &nameChinesses, &nameRussian)
fmt.Printf("Name Spainish %s - Name Chinesses %s - Name Russian %s", nameSpainish, nameChinesses, nameRussian)
}
rows.Close()
db.Close()
}
当前输出：
Habitación doble ???? ?????????
期望输出：
Habitación doble 雙人房 двухместный номер

I've got set up a machine with Ubuntu 12.04 LTS(64bits), Go 1.2.2 and go-oci8(github.com/mattn/go-oci8), but when I executed a query on Database Oracle 11G, it returned wrong characters on Russian and chinese.
I've tried to set up the NLS_LANG field on my proyect as is show it below:
os.Setenv("NLS_LANG", "SIMPLIFIED CHINESE_CHINA.AL32UTF8")
os.Setenv("NLS_LANG", "AMERICAN_AMERICA.AL32UTF8")
os.Setenv("NLS_LANG", "RUSSIAN_CIS.AL32UTF8")
Someone can help me, what configuration of NLS_LANG I should put to get the right characters on Russian, Chinese or other difference languages than English and Spanish?
This is the example:
1.
Create table room
{
name_spainish varchar2(100),
name_chinesses varchar2(100),
name_russian varchar2(100)
}
2.
insert into room (name_spainish, name_chinesses, name_russian) values ('Habitación doble','雙人房','двухместный номер')
3.
package main
import (
"database/sql"
"fmt"
"os"
_ "github.com/mattn/go-oci8"
)
func main() {
ExecQuery("select name_spainish, name_chinesses, name_russian from room")
}
func ExecQuery(query string){
os.Setenv("NLS_LANG", "AMERICAN_AMERICA.AL32UTF8")
db, err := sql.Open("oci8", "user/userps@host:1521/SID")
if err != nil {
fmt.Println(err)
return
}
rows, err := db.Query(query)
if err != nil {
fmt.Println(err)
return
}
for rows.Next() {
var nameSpainish string
var nameChinesses string
var nameRussian string
rows.Scan(&nameSpainish, &nameChinesses, &nameRussian)
fmt.Printf("Name Spainish %s - Name Chinesses %s - Name Russian %s", nameSpainish, nameChinesses, nameRussian)
}
rows.Close()
db.Close()
}
current output:
Habitación doble ???? ?????????
expect output:
Habitación doble 雙人房 двухместный номер

这个问题已经通过将值转换为十六进制来解决，使用以下查询：
select RAWTOHEX(UTL_RAW.cast_to_raw(name_spainish, name_chinesses, name_russian)) from room
在代码中，添加了encoding/hex包和hex.DecodeString(texto)函数。
for rows.Next() {
var nameSpainish string
var nameChinesses string
var nameRussian string
rows.Scan(&nameSpainish, &nameChinesses, &nameRussian)
dataSpainish, _ := hex.DecodeString(nameSpainish)
dataChinesses, _ := hex.DecodeString(nameChinesses)
dataRussian, _ := hex.DecodeString(nameRussian)
fmt.Printf("Name Spainish %s - Name Chinesses %s - Name Russian %s", string(dataSpainish), string(dataChinesses), string(dataRussian))
}
英文:
This problem had been solved converting the values into hexadecimal using the follow query
select RAWTOHEX(UTL_RAW.cast_to_raw(name_spainish, name_chinesses, name_russian)) from room
On code was adding the package encoding/hex and the function hex.DecodeString(texto).
for rows.Next() {
var nameSpainish string
var nameChinesses string
var nameRussian string
rows.Scan(&nameSpainish, &nameChinesses, &nameRussian)
dataSpainish, _ := hex.DecodeString(nameSpainish)
dataChinesses, _ := hex.DecodeString(nameChinesses)
dataRussian, _ := hex.DecodeString(nameRussian)
fmt.Printf("Name Spainish %s - Name Chinesses %s - Name Russian %s", string(dataSpainish), string(dataChinesses), string(dataRussian))
}
