win 需要先安裝luaforwindows
linux 需要安裝 luarocks 并 luarocks install luasql-mysql

									require"luasql.mysql"

									--創建環境對象

									env=luasql.mysql()

									--連接數據庫

									conn=env:connect("數據庫名","用戶名","密碼","IP地址",端口)

									--設置數據庫的編碼格式

									conn:execute"SET NAMES GB2312"

									--執行數據庫操作

									cur=conn:execute("select * from role")

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

									while row do

									var=string.format("%d%s\n",row.id,row.name)

									print(var)

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

									end

									conn:close()--關閉數據庫連接

									env:close()--關閉數據庫環境

上面是個簡單的，我們再來看個稍微復雜些的例子

									-- load driver 

									require "luasql.mysql"

									-- create environment object 

									env = assert (luasql.mysql()) 

									-- connect to data source 

									con = assert (env:connect("database", "usr", "password", "192.168.xx.xxx", 3306)) 

									-- reset our table 

									res = con:execute"DROP TABLE people"        --建立新表people 

									res = assert (con:execute[[ 

									CREATE TABLE people(        

									  name varchar(50), 

									  email varchar(50) 

									) 

									]]) 

									-- add a few elements 

									list = { 

									{ name="Jose das Couves", email="[email protected]", }, 

									{ name="Manoel Joaquim", email="[email protected]", }, 

									{ name="Maria das Dores", email="[email protected]", }, 

									} 

									for i, p in pairs (list) do                      --加入數據到people表 

									res = assert (con:execute(string.format([[ 

									  INSERT INTO people                      

									  VALUES ('%s', '%s')]], p.name, p.email) 

									)) 

									end 

									-- retrieve a cursor 

									cur = assert (con:execute"SELECT name, email from people")  --獲取數據 

									-- print all rows 

									row = cur:fetch ({}, "a") -- the rows will be indexed by field names  --顯示出來 

									while row do

									print(string.format("Name: %s, E-mail: %s", row.name, row.email)) 

									row = cur:fetch (row, "a") -- reusing the table of results 

									end 

									-- close everything 

									cur:close() 

									con:close() 

									env:close()
