是否可以在存储过程中的xquery insert语句中使用nvarchar类型的sproc变量? 我的意思是这样的,只有当存在具有seek值的子元素时才会插入元素:
DECLARE @profiles_xml xml
DECLARE @profile_id int
DECLARE @user_id nvarchar(50)
SET @profile_id = 20
SET @user_id ='BC4A18CA-AFB5-4268-BDA9-C990DAFE7783'
SET @profiles_xml = (SELECT profiles from tbl_applied_profiles WHERE profiles.value('(Profile/ID)[1]','int')= @profile_id)
SET @profiles_xml.modify('
insert
if(/Profile/User/ID="user_id")
then <Activity>activity_name5</Activity>
else()
as first
into (/Profile/User/Activities)[1]')
@profiles_xml包含的xml如下所示:
<Profile>
<ID>20</ID>
<User>
<ID>BC4A18CA-AFB5-4268-BDA9-C990DAFE7783</ID>
<Name>somename</Name>
<Activities>
<Activity>activity_name2</Activity>
</Activities>
</User>
</Profile>
答案 0 :(得分:0)
您需要使用sql:variable("@user_id")
,即
SET @profiles_xml.modify('
insert
if(/Profile/User/ID=sql:variable("@user_id"))
then <Activity>activity_name5</Activity>
else()
as first
into (/Profile/User/Activities)[1]');
select @profiles_xml;
