MacBook Linux Windows等系统安装sqlite3

MacBook Linux 树莓派raspberrypi安装Golang环境

sqlite3基本操作

sqlite3  /Users/liang/Downloads/foo.db
.databases
.quit
.exit
.tables

CREATE TABLE `userinfo` (
`uid` INTEGER PRIMARY KEY AUTOINCREMENT,
`username` VARCHAR(64) NULL,
`departname` VARCHAR(64) NULL,
`created` DATE NULL
);

CREATE TABLE `userdeatail` (
`uid` INT(10) NULL,
`intro` TEXT NULL,
`profile` TEXT NULL,
PRIMARY KEY (`uid`)
);

.schema userinfo

golang操作sqlite3

package main

import (
    "database/sql"
    "fmt"
    _ "github.com/mattn/go-sqlite3"
)

func main() {
    db, err := sql.Open("sqlite3", "/Users/liang/Downloads/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", "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() {

        fmt.Println(username)
        fmt.Println(department)
        fmt.Println(created)

    //删除数据

    checkErr(err)

    fmt.Println(affect)

    db.Close()

}

func checkErr(err error) {
    if err != nil {
        panic(err)
