sql where后面字段赋值参数不能为text，于是改成varchar

create proc proc_Mdata
 @where varchar(500),--条件
 @msetdate datetime--当天时间
as
begin
--声明空白数据
DECLARE @tbnull TABLE(id INT,[time] DATETIME,[count] INT)
--递增变量
DECLARE @day INT
SET @day=0
--当月天数
DECLARE @days INT
SELECT @days=day(dateadd(mm,1,@msetdate)-day(@msetdate))
--循环插入空白数据
WHILE (@day<@days)
BEGIN
SET @day=@day+1;
declare @timeloop datetime;
set @timeloop=CONVERT(DATETIME,CONVERT(VARCHAR(8),@msetdate,120)+RIGHT('00'+@day,2));
declare @num int;
--select @num=count(*) from TB where (CONVERT(VARCHAR(10),[time],120))=@timeloop
SELECT @num=COUNT(AID)
FROM (SELECT AID, MODE, created
        FROM Bs_RCode
        GROUP BY AID, MODE, created
        HAVING (MODE = @where) AND (CONVERT(VARCHAR(10),[created],120))=@timeloop) DERIVEDTBL

INSERT INTO @tbnull(id,[time],count)
VALUES(1,@timeloop,@num)
END;
select * from @tbnull
end
