Scott,

You're right.

Combined with the other suggestions, how about this?

CAST(CASE
WHEN ( Number_Deleted_Rows = 0 ) THEN 0
WHEN ( Number_Rows = 0 ) AND ( Number_Deleted_Rows > 0 ) THEN 100.00
WHEN Number_Rows = Number_Deleted_Rows THEN 50.00
ELSE (100 * Number_Deleted_Rows / ( Number_Rows + Number_Deleted_Rows ) )
END
AS DECIMAL( 5 , 2 )
) AS Percent_Deleted

Might not even need the third WHEN.

Robert,

Your first two whens can be combined into one

WHEN Number_Deleted_Rows = 0 THEN 0

Also, your very last when doesn't return 'Percent deleted', consider 1 Row and 5 deleted. Returns 20%. The more deleted the smaller the percent, is that what you really want? You may be able to use the when before that as an ELSE catchall.
