forwarding a lua code to another -


i have lua code called lua file , wants assign value , print out value getting "nil", please me. here code:

function main_setup()    package.path = package.path ..";c:/users/kude/desktop/mqtt1/?.lua"                  require "ds18b20"  end  local = main_setup()  print(a)

output:

nil

function main_setup()    package.path = package.path ..";c:/users/kude/desktop/mqtt1/?.lua"                  require "ds18b20" end

this function not return anything.

so

local = main_setup()

is equivalent to

local = nil

hence

nil

is expected output of

print(a)

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
