golang之操作sqlite

一、创建测试表

SQL语句如下：

CREATE TABLE userinfo(
   uid INTEGER PRIMARY KEY AUTOINCREMENT,
   username           TEXT    NOT NULL,
   departname         TEXT    NOT NULL,
   created        TEXT
);

二、golang操作SQLite

具体语句如下：

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("361way", "研发部", "2019-03-06")
    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("361wayupdate", 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)
    }
}
