使用sql数据库驱动程序

最终用户（开发或生产）能否推荐一个最好使用“database/sql”包的 Sql 驱动程序包。我对 Postgres、ODBC、MySql（可能还有其他东西，但对于大容量的东西 - 即不是 Sqlite）感兴趣，它们最好可以在 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。欢迎任何相关意见。

GO-SQL-驱动程序（MySQL）：

https://github.com/Go-SQL-Driver/MySQL

样本表：

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：

https://github.com/bmizerany/pq

样本表：

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, err := stmt.Exec("reckhou", "IT", "2010-10-01")
    checkErr(err)

    id, err := res.LastInsertId()
    checkErr(err)

    fmt.Println(id)

    // Update
    stmt, err = db.Prepare("update userinfo set username=$1 where uid=$2")
    checkErr(err)

    res, err = stmt.Exec("update", 1)
    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=$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)
