1、根据存入条件操作不同sql语句。

ALTER PROCEDURE dbo.selectCustomerCNameCount
@customerID int
AS
if @customerID=-1
begin
select contentownerid ,userCName,count(*) as countAll from view_usercomment group
by contentownerid,userCName order by contentownerid DESC
end
else
begin
select contentownerid ,userCName,count(*) as countAll from view_usercomment where
contentownerid=@customerID group by contentownerid,userCName order by contentownerid
DESC
end
