求指点写的存储过程哪里有问题？

Question

/*1、执行存储过程未更新任何数据： 
execute dbo.pro_alarm_update_qr @s_zyh ='00024893' , @dt_jyrq ='2016-1-9 22:52:8.653' , @s_yq ='血球仪BF6800' , @s_ybh ='2601094769' , @s_xmbh ='13' , @dt_sendtime ='2016-1-9 22:52:8.653' , @s_czybh ='9999 管理员' , @dt_qrsj ='2016-1-10 10:29:8.616' */

--过程内容:
alter   PROCEDURE [dbo].[pro_alarm_update_qr]      
 @s_zyh     varChar(20), 
 @dt_jyrq    DateTime,  
 @s_yq      varchar(10), 
 @s_ybh     varchar(20), 
 @s_xmbh    varchar(20),
 @dt_sendtime datetime,
 @s_czybh   varchar(20),
 @dt_qrsj   datetime   
AS   
     update interface_lis_pacs..inter_lab_resultalert set hischeckman=@s_czybh,hischeckdt=@dt_qrsj
     where alertdt = @dt_jyrq and rptunitname=@s_yq and barcode=@s_ybh and rpt_itemid=@s_xmbh and alertdt = @dt_sendtime
go
-------------------------------------------------------------------------------
--2、把参数传进去,单独执行查询有数据,而且update也能够成功更新数据
     select * --  update a  set hischeckman=@s_czybh,hischeckdt=@dt_qrsj
     from interface_lis_pacs..inter_lab_resultalert a 
     where alertdt = '2016-1-9 22:52:8.653' and rptunitname='血球仪BF6800' and barcode='2601094769' and rpt_itemid='13' and alertdt = '2016-1-9 22:52:8.653' 

Answer 1

楼主 你测试一下
--2、把参数传进去,单独执行查询有数据,而且update也能够成功更新数据
select * -- update a set hischeckman=@s_czybh,hischeckdt=@dt_qrsj
from interface_lis_pacs..inter_lab_resultalert a
where alertdt = '2016-1-9 22:52:8.653' and rptunitname='血球仪BF6800' and barcode='2601094769' and rpt_itemid='13' and alertdt = '2016-1-9 22:52:8.653'

    把这段后面的where条件删除，看看能不能查询出数据
    然后再把条件一个一个带入
