I am trying to format my result to a percentage with 0 decimals. This is what I have for the formatting/SQL syntax. Can anyone help me reset this to work correctly? Right now when the results are displayed it shows this for an example: 100.00000000%

CASE WHEN (jodrtg.fnqty_comp / jodrtg.foperqty) * 100 > 0 AND jodbom.fqty_iss = '0' AND joitem.fprodcl = '01' THEN ((Round(jodrtg.fnqty_comp, 0) / Round(jodrtg.foperqty, 0)) * Round(100, 0)) * - 1 ELSE (Round(jodrtg.fnqty_comp, 1) / Round(jodrtg.foperqty, 0)) * Round(100, 0) END * 1) + '%' AS [% CMP]

you can try to cast as an integer;

cast(CASE WHEN (jodrtg.fnqty_comp / jodrtg.foperqty) * 100 > 0 AND jodbom.fqty_iss = '0' AND joitem.fprodcl = '01' THEN ((Round(jodrtg.fnqty_comp, 0) / Round(jodrtg.foperqty, 0)) * Round(100, 0)) * - 1 ELSE (Round(jodrtg.fnqty_comp, 1) / Round(jodrtg.foperqty, 0)) * Round(100, 0) END * 1) as integer) + '%' AS [% CMP]

Use this:
cast(cast(round(
		CASE 
			WHEN (jodrtg.fnqty_comp / jodrtg.foperqty) * 100 > 0 AND jodbom.fqty_iss = '0' AND joitem.fprodcl = '01' 
				THEN  
					-(jodrtg.fnqty_comp / jodrtg.foperqty *100.0)
			ELSE 
				jodrtg.fnqty_comp /jodrtg.foperqty * 100.0
		END
	,0) as int) as varchar(5)) + '%' AS [% CMP]

Neither of those seem to be working. I am getting a syntax errors when I try to execute my query.

Error in list of function arguments: 'AS' not recognized.
Error in list of function arguments: ',' not recognized.
Unable to parse query text.

you have an extra )

try this:
CAST(CAST(CASE 
WHEN (jodrtg.fnqty_comp / jodrtg.foperqty) * 100 > 0 AND jodbom.fqty_iss = '0' AND joitem.fprodcl = '01' 
THEN ((Round(jodrtg.fnqty_comp, 0) / Round(jodrtg.foperqty, 0)) * Round(100, 0)) * - 1 
ELSE (Round(jodrtg.fnqty_comp, 1) / Round(jodrtg.foperqty, 0)) * Round(100, 0) 
END * 1 AS INT) AS VARCHAR) + '%' 
AS [% CMP]

I mentioned that I edited my post because it had errors. I will post it again here:
cast(cast(round(
		CASE 
			WHEN (jodrtg.fnqty_comp / jodrtg.foperqty) * 100 > 0 AND jodbom.fqty_iss = '0' AND joitem.fprodcl = '01' 
				THEN  
					-(jodrtg.fnqty_comp / jodrtg.foperqty *100.0)
			ELSE 
				jodrtg.fnqty_comp /jodrtg.foperqty * 100.0
		END
	,0) as int) as varchar(5)) + '%' AS [% CMP]

Eric's post will not round the values correctly. You have to use ROUND before casting to int.
select 100.0/6, cast(100.0/6 as int), cast(round(100.0/6, 0) as int)

--------------------------------------- ----------- -----------
                              16.666666          16          17

Actually he did use round but twice inside the case branches, which could be multiple. I used it only once wrapping the whole case statement, which I think is the better way.
