我试图选择数据库中所有函数及其依赖项的列表。
(如果我手动查看依赖关系并选择依赖于[function]'选项的'对象,则会出现依赖关系。)
我的主要问题是将每个函数的所有依赖项汇总到一行。
我已尝试使用stuff
,但出于某种原因,我无法在此背景下使用它。
select
o.name
, stuff((select N', ' + Name from sys.objects o3 where o3.object_id = o2.object_id for xml path ('')), 1, 1, N'') as Dependencies
from sys.objects o
left join sys.sql_expression_dependencies sed
on object_id = referenced_id
left join sys.objects o2
on referencing_id = o2.object_id
where o.type='FN'
order by o.name
我哪里错了?
答案 0 :(得分:4)
这可能对您有用:
SELECT
O.Name
,T.Dependencies
FROM sys.Objects O
OUTER APPLY
(
SELECT SUBSTRING(
(
SELECT ',' + OBJECT_NAME(D.referenced_id)
FROM sys.SQL_Expression_Dependencies D
WHERE D.referencing_id = O.Object_ID
GROUP BY OBJECT_NAME(D.referenced_id)
ORDER BY OBJECT_NAME(D.referenced_id)
FOR XML PATH('')
)
,2,4000) AS Dependencies
) T
WHERE O.Type = 'FN'
ORDER BY O.Name
;
如果没有,请告诉我有关遗失的内容,我可以从那里开始。祝好运! :)
