luasql在Fedora20下的安装与使用示例

主要参考:http://www.boll.me/archives/614

luasql安装, 在终端通过yum命令安装:

yum -y install lua-sql

接下来写个测试的lua脚本文件(通过lua连接mysql数据库),如:

#!/usr/bin/lua



local luasql = require "luasql.mysql"

local env = assert(luasql.mysql())

local con = assert(env:connect("mysql", "root", "123", "192.168.1.90", 3306))

local cur = assert(con:execute("show databases"))

local row = cur:fetch ({}, "a")

 

while row do

    print(row.Database)

    row = cur:fetch (row, "a")

end



cur:close()

con:close()

env:close()

运行结果:

[zcm@vm-fedora20 lua]$ ./mysql.lua 

information_schema

mysql

performance_schema

sakila

test

world
