这个存储过程中加了
-- 订单礼品名称
and a.giftname like
case
when (@giftname= ' ' or @giftname is null) then a.giftname
when (@giftname is not null) then '% ' + @giftname + '% '
end
后,有点订单查不出来?应该怎么解决?
[解决办法]
改为:
and a.giftname like
case
when (@giftname= ' ' or @giftname is null) then a.giftname+ '% '
when (@giftname is not null) then '% ' + @giftname + '% '
end
[解决办法]
太长了,帮你ding!
[解决办法]
-- 订单礼品名称
and a.giftname like
case
when (@giftname= ' ' or @giftname is null) then a.giftname
when (@giftname is not null) then '% ' + @giftname + '% '
end

=======> 你多加条件了,当然查出记录就少了,你加的句子语法是没有问题的,问题出在你要表达的意思和你加的语句不相符,所以你应该说明你要添加什么条件,我们才好帮你判断你的语句是不是对的.
