SQLCMD use LIKE '%#%' - variables

Question

I'm trying to run a query using SQLCMD.EXE and have trouble with the LIKE portion.
WHERE email LIKE '%%#%%'
I think it is an error with cmd prompt rather then SQLCMD.EXE since I get the error:
Syntax error "#%'"
I am running this via Notepad++ (NppExec) pointing to the bat file like so:
H:\scripts\SQL.bat "$(CURRENT_WORD)"
This causes the query to be wrapped in double quotes before being used by the SQLCMD.EXE call. The SQLCMD.EXE call then runs in the bat file like so:
SQLCMD.EXE -U user -P %pass% -S %server% -Q %sql% -d %table%
It works perfect on any query I use aside from this LIKE '%%#%%' part.
UPDATE
I've done a few more tests and think I have narrowed it down to being a problem with the % and the #.
So queries like these work fine:
SELECT name FROM table WHERE name LIKE 'test'
SELECT name FROM table WHERE name LIKE 'test%'
SELECT name FROM table WHERE name LIKE '%%test'
But these will cause errors:
SELECT name FROM table WHERE name LIKE '%test'
SELECT name FROM table WHERE name LIKE '%test%'
This is fine since I am ok with doubling the % in my queries, but I've tried %%#% and %%#%% and they throw errors. Syntax error "#'"" or Syntax error "#%'"", respectively.
Also, the reason for the variables is that I included some logic so it can detect table names and run for different servers and databases.
Here is the bat file
set sql=%1
iff %#index[%sql%,sur_] GT -1 THEN
SET SERVER=server1
SET table=tablename
SET pass=password
else
SET SERVER=server2
SET table=tablename
SET pass=password
endiff
SQLCMD.EXE -U usr -P %pass% -S %server% -Q %sql% -d %table%
The reason for the weird syntax is due to the command being run through TCC/LE (see here)

Answer 1

I'm not quite sure what your reasoning is for doubling up the %s, but it looks like your intent is to find values in the email column that contain #. If so, you can try rewriting the clause as such:
WHERE CHARINDEX('#', email) > 0
If it's the # symbol that is tripping things up, use CHAR(64) instead.
WHERE CHARINDEX(CHAR(64), email) > 0

Answer 2

When run query with sqlcmd, i found that % symbol will be removed. Let's say your query is :
SELECT name FROM table WHERE name LIKE 'test%'
The sqlcmd will read your query as
SELECT name FROM table WHERE name LIKE 'test'
So sqlcmd will not filter your result. Please use %% for query
SELECT name FROM table WHERE name LIKE 'test%%'
and you will get result
SELECT name FROM table WHERE name LIKE 'test%'
I have tested this on SQLServer 2005 & 2008
