golang使用sqlite

安裝問題

在import sqlite的時候，golang build 出現如下錯誤，

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

緣由是sqlitle3是個cgo庫，須要gcd編譯c代碼
而後下載安裝tdm-gcc便可（windosw版本）下載地址：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)

//插入數據
stmt, err := db.Prepare("INSERT INTO userinfo(username, departname, created) values(?,?,?)")
checkErr(err)

res, err := stmt.Exec("astaxie", "研發部門", "2012-12-09")
checkErr(err)

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

fmt.Println(id)
//更新數據
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)

//查詢數據
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)
}

//刪除數據
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)
}
}
```
