安装问题

在import sqlite的时候，golang build 出现以下错误，

exec: "gcc": executable file not found in %PATH%

原因是sqlitle3是个cgo库，需要gcd编译c代码

然后下载安装tdm-gcc即可（windosw版本）下载地址：http://tdm-gcc.tdragon.net/download

在golang中使用sqlite3

package main

import (

"database/sql"

"fmt"

_ "github.com/mattn/go-sqlite3"

)

func main() {

db, err := sql.Open("sqlite3", "./foo.db")

checkErr(err)

//插入数据

stmt, err := db.Prepare("INSERT INTO userinfo(username, departname, created) values(?,?,?)")

checkErr(err)

res, err := stmt.Exec("astaxie", "研发部门", "2012-12-09")

checkErr(err)

id, err := res.LastInsertId()

checkErr(err)

fmt.Println(id)

//更新数据

stmt, err = db.Prepare("update userinfo set username=? where uid=?")

checkErr(err)

res, err = stmt.Exec("astaxieupdate", id)

checkErr(err)

affect, err := res.RowsAffected()

checkErr(err)

fmt.Println(affect)

//查询数据

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)

}

//删除数据

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)

}

}
