使用sql數據庫驅動程序

Question

最終用戶（開發或生產）請推薦一個最好使用「database/sql」包的Sql驅動程序包。我對Postgres，ODBC，MySql感興趣（可能還有其他的東西，但對於高容量 - 即不是Sqlite），可以優先在Windows和/或Linux（最好是兩者）上使用。爲了我的興趣，它可能需要最近更新/維護，並且必須使用最新的Go版本。效率（吞吐量）顯然是重要的。歡迎任何相關意見。

GO-SQL驅動程序（MySQL的）：

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

樣品表：

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`) 
) 

樣品的編號：

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) 
    } 
} 

PostgreSQ L：

樣品表：

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); 

示例代碼：

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) 
    } 
}
