使用sql数据库驱动程序

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.

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：

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)
    }
}
