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

````js
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)
}
}
```
