最终用户(开发或生产)是否可以推荐一个最好使用“database / sql”包的sql驱动程序包.我对Postgres,ODBC,MysqL(以及可能的其他东西,但对于高容量 – 即不是sqlite)感兴趣,最好可以在Windows和/或Linux(最好是两者)上使用.为了让我感兴趣,它可能需要最近更新/维护,并且必须与最新的Go版本一起使用.效率(吞吐量)显然很重要.欢迎任何相关评论.
解决方法
GO-sql的驱动程序(MysqL的)：
07000
样品表：
CREATE TABLE `userinfo` (
`uid` INT(10) NOT NULL AUTO_INCREMENT,`username` VARCHAR(64) NULL DEFAULT NULL,`departname` VARCHAR(64) NULL DEFAULT NULL,`created` DATE NULL DEFAULT NULL,PRIMARY KEY (`uid`)
)
CREATE TABLE `userdetail` (
`uid` INT(10) NOT NULL DEFAULT '0',`intro` TEXT NULL,`profile` TEXT NULL,PRIMARY KEY (`uid`)
)
示例代码：
package main
import (
_ "github.com/Go-sql-Driver/MysqL"
"database/sql"
"fmt"
)
func main() {
db,err := sql.Open("MysqL","reckhou:reckhou@/test?charset=utf8")
checkErr(err)
//Insert
stmt,err := db.Prepare("INSERT userinfo SET username=?,departname=?,created=?")
checkErr(err)
res,err := stmt.Exec("reckhou","IT","2010-10-02")
checkErr(err)
id,err := res.LastInsertId()
checkErr(err)
fmt.Println(id)
// Update
stmt,err = db.Prepare("update userinfo set username=? where uid=?")
checkErr(err)
res,err = stmt.Exec("update",id)
checkErr(err)
affect,err := res.RowsAffected()
checkErr(err)
fmt.Println(affect)
//Query
rows,err := db.Query("SELECT * FROM userinfo")
checkErr(err)
for rows.Next() {
var uid int
var username string
var department string
var created string
err = rows.Scan(&uid,&username,&department,&created)
checkErr(err)
fmt.Println(uid)
fmt.Println(username)
fmt.Println(department)
fmt.Println(created)
}
//Delete
stmt,err = db.Prepare("delete from userinfo where uid=?")
checkErr(err)
res,err = stmt.Exec(id)
checkErr(err)
affect,err = res.RowsAffected()
checkErr(err)
fmt.Println(affect)
db.Close()
}
func checkErr(err error) {
if err != nil {
panic(err)
}
}
Postgresql的：
07001
样品表：
CREATE TABLE userinfo
(
uid serial NOT NULL,username character varying(100) NOT NULL,departname character varying(500) NOT NULL,Created date,CONSTRAINT userinfo_pkey PRIMARY KEY (uid)
)
WITH (OIDS=FALSE);
CREATE TABLE userdeatail
(
uid integer,intro character varying(100),profile character varying(100)
)
WITH(OIDS=FALSE);
示例代码：
import (
"database/sql"
"fmt"
_ "github.com/bmizerany/pq"
)
func main() {
db,err := sql.Open("postgres","user=reckhou password=reckhou dbname=test sslmode=disable")
checkErr(err)
//Insert
stmt,err := db.Prepare("INSERT INTO userinfo(username,departname,created) VALUES($1,$2,$3) RETURNING uid")
checkErr(err)
res,"2010-10-01")
checkErr(err)
id,err = db.Prepare("update userinfo set username=$1 where uid=$2")
checkErr(err)
res,1)
checkErr(err)
affect,err := res.RowsAffected()
checkErr(err)
fmt.Println(affect)
// Query
rows,&created)
checkErr(err)
fmt.Println(uid)
fmt.Println(username)
fmt.Println(department)
fmt.Println(created)
}
// Delete
stmt,err = db.Prepare("delete from userinfo where uid=$1")
checkErr(err)
res,err = stmt.Exec(1)
checkErr(err)
affect,err = res.RowsAffected()
checkErr(err)
fmt.Println(affect)
db.Close()
}
func checkErr(err error) {
if err != nil {
panic(err)
}
}
