Find all dependencies of a list of stored procedures - sql-server

Question

We have a list of 51 stored procedures used in our application.
I need to find out the names of all the functions and stored procedures called by those stored procs
Is there a quick way to find out what our stored procedures are calling?
I tried using sys.dm_sql_referencing_entities as below
SELECT
referencing_schema_name +'.'+ referencing_entity_name AS ReferencedEntityName,
referencing_class_desc AS ReferencingEntityDescription
FROM sys.dm_sql_referencing_entities ('dbo.sp_GetPayRunDetails', 'OBJECT');
GO
but I am hoping that there is a way to check all 50 stored procs and get detailed information about what other objects (stored procs, and functions) that they call...
I don't want to do this manually is because I also need recursive dependencies for the stored procs and functions that are called...

This query might do the trick for you:
WITH cteDependencies AS (
SELECT e.referencing_id object_id, e.referencing_id, e.referenced_id, e.referenced_schema_name, e.referenced_entity_name
FROM sys.sql_expression_dependencies e
WHERE e.referencing_id = OBJECT_ID('dbo.sp_GetPayRunDetails')
UNION ALL
SELECT d.object_id, e.referencing_id, e.referenced_id, e.referenced_schema_name, e.referenced_entity_name
FROM sys.sql_expression_dependencies e
JOIN cteDependencies d ON d.referenced_id = e.referencing_id AND e.referenced_id <> e.referencing_id
)
SELECT OBJECT_NAME(d.object_id) source_name, d.*
FROM cteDependencies d
JOIN sys.all_objects o ON d.referenced_id = o.object_id
WHERE o.[type] IN ('P','FN','TF'); -- for a list of types see https://msdn.microsoft.com/en-us/library/ms178618.aspx?f=255&MSPPError=-2147217396
Note that it will fail on circular references; if you have such, you need to track the dependency path (for instance in a XML column) and skip items which are repeated.
You can change the "source" by altering the OBJECT_ID('dbo.sp_GetPayRunDetails') filter to include the SPs you want to analyze.

Answer 2

I had a function. Modify it as per your means. It manages self-references
CREATE FUNCTION GetDependents(
#ObjectName AS SYSNAME
)
RETURNS #result TABLE ( Seq INT IDENTITY, ObjectName SYSNAME, Hierarchy VARCHAR(128) , objNameStr varchar(max) )
AS
BEGIN
;WITH Obj AS (
SELECT DISTINCT s.id AS ParentID, s.DepID AS ObjectID, o1.Name AS ParentName, o2.Name AS ChildName,
QUOTENAME(sch1.name) + '.' + QUOTENAME(o1.Name) + '(' + RTRIM(o1.type) + ')' COLLATE SQL_Latin1_General_CP1_CI_AS
AS ParentObject,
QUOTENAME(sch2.name) + '.' + QUOTENAME(o2.Name) + '(' + RTRIM(o2.type) + ')' COLLATE SQL_Latin1_General_CP1_CI_AS AS ObjectName,
o2.Name as objNameStr
FROM sys.sysdepends s
INNER JOIN sys.all_objects o1 ON s.id = o1.object_id
INNER JOIN sys.schemas sch1 ON sch1.schema_id = o1.schema_id
INNER JOIN sys.all_objects o2 on s.DepID = o2.object_id
INNER JOIN sys.schemas sch2 ON sch2.schema_id = o2.schema_id
where o2.type not in ('u') and s.id <>s.DepID --Self Reference ko hata...
), cte AS (
SELECT
0 AS lvl,
ParentID,
ObjectId,
ParentObject,
ObjectName,
CAST(ObjectID AS VARBINARY(512)) AS Sort
, objNameStr
FROM obj WHERE ParentName = #ObjectName
UNION ALL
SELECT
p.lvl+ 1,
c.ParentID,
c.ObjectId,
c.ParentObject,
c.ObjectName,
CAST(p.sort + CAST(c.ObjectID AS VARBINARY(16))
AS VARBINARY(512)), c.objNameStr
FROM cte p
INNER JOIN obj c ON p.ObjectID = c.ParentID
)
INSERT INTO #result (ObjectName, Hierarchy,objNameStr)
SELECT
ObjectName,
'|-' + REPLICATE('-',(lvl * 4)) + ObjectName,
objNameStr
FROM cte
ORDER BY Sort
OPTION (MAXRECURSION 32767);
RETURN
END
