Lua Array from DataBase

Hello. I new to use lua at Asterisk and have question about array from DB at lua

I use asterisk ODBC conection at DataBase to get variables for my dialplan from DB.
at the extensions.conf I may use this


(GET_VALUE req exists at func_odbc)

This construction works fine. But now I need same result at Lua. This interface great works with one returned var

var1 = ODBC_GET_VALUE():Get()

But When I try get 2 or more vars from my DB - it’s failed. I use construction like this

var1,var2 = channel.ODBC_GET_VALUE():Get()

(offcourse I change func_odbc.conf req and SELECT 2 values for this req)

So how to execute array of values at lua?
