windows - Why does %%I work in .cmd? -


i have found in multiple online forums , blogs .cmd files utilize %i (or %a, etc.) loops , batch files require 2 percent symbols (%%i). however, line of code has been working me in .cmd file:

for /l %%i in (%case%, 1, %endcase%) ( aws s3 cp s3://[url]/%user%/%%i "c:\users\[directories]\accuracy_testing\datax\%user%_%%i" --recursive )

in code, using command line interface aws download files associated multiple ids. case , endcase arguments parsed file.

why work, when .cmd files should using %i instead of %%i?

you're confusing .cmd files cmd prompt. .cmd files batch files (with few differences people won't notice), while cmd prompt command line itself.

scripts use %%i, command prompt uses %i.

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() .
