golang使用sqlite

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年12月09日")
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)
}
}
```
