Hi,
 
Try This... Your Dynamic Query is Wrongly Framed.
 
BEGIN
    DECLARE @QRY NVARCHAR(500)
    DECLARE @ORDER INT=2
    SELECT @QRY='SELECT * FROM [dbo].[LIBMAST] WHERE (1=1) ' + CASE WHEN @ORDER=1 THEN 'ORDER BY ACCNO ' ELSE 'ORDER BY CALLNO' END
    PRINT @QRY
END

Hi Josh
 
You have to cast the INT to NVARCHAR. I have modified your query like belw:
 
DECLARE @QRY VARCHAR(300)
DECLARE @ORDER INT
SET @QRY = N'SELECT * FROM [dbo].[datalog_574T] WHERE (1=1)'
SET @QRY = @QRY + 'CASE'+ CAST(@ORDER AS NVARCHAR(10)) +' WHEN' + CAST(1 AS NVARCHAR(1))+ 'THEN ''ORDER BY ACCNO'' ELSE ''ORDER BY CALLNO''END'
