Hi Irene,

Your select string is 246 characters long which requires double size (492) to store as nvarchar. It shouldn't be and it isn't trancated when I run your code with nvarchar(500). Btw, the nvarchar variable can be up to 4000 characters.
Anyway, you can get desired result w/o dynamic sql.

select cl_code, cl_init, cl_fname, cl_lname, cl_cltype, cl_language, cs_telno, cs_smrecno, cs_freq' + 
	from bkclsmscl left join bkclporg on cs_clrecno = cl_recno
	where (cl_celno <> 'DELETE' or cl_action is null)  
		and LEN(cl_celno) = 10 
		AND (@cs_smrecno NOT BETWEEN 1 AND 7 OR cl_smsi = 1)

>I need to build up an select statement depending on the parameters being passed through. The total size exceeds 256 charcaters and therefor truncating the variable. The variable is defined as @statement nvarchar(256). I tried to use nvarchar(500), but nothing changes.
