Executing LuaSql script via mysql proxy

[Jerwin Roy]

I am a newbie to mysql-proxy.Is it possible to execute LuaSql scripts via mysql-proxy?I have tried the following code:

--connect.lua
mysql = require "luasql.mysql"
env = assert(mysql.mysql())
con = assert (env:connect ("db_name", "username", "password", "hostname", "3306"))
local cur = con:execute("select * from approval")
myTable[0] = 0
myTable = {}
row = cur:fetch(myTable, "a")
print(myTable.id,myTable.user)

Then i am getting the following error in my error log:
mysql.lua:8: bad argument #1 to 'insert' (table expected, got nil)

But when i execute the same code without mysql-proxy i am able to get the required data.Can anyone solve this issue ? Thanks in advance.
