node.js - path.join does not work? -


i want read path , wrote 2 different codes.the first code not work second code works perfectly. not understand differences. can explain me going on? thanks. file stored in /modules/config/

first code:

var tmpmodulepath = path.join('./modules/',"config/"); var moduleconfiginfo = require(tmpmodulepath + "_test.js");

second code:

var tmpmodulepath = path.join('./modules/',"config/"); var moduleconfiginfo = require("./" + tmpmodulepath + "_test.js");

from first code, error: can not find module ..._tset.csv

if console.log generated path results:

first code block:

"modules/config/_test.js"

second code block:

"./modules/config/_test.js"

in second case, have relative path starting current directory (./). require modules folder starting current directory.

in first case, path absolute, meaning require modules folder starting root path of filesystem.

i hope understand difference now.

what want use in case path.resolve:

var tmpmodulepath1 = path.resolve('./', 'modules/',"config/", 'test.js');

check answer this question understand difference between .join , .resolve.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

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() .
