Find out the calling database in a sproc called from a different database

Question

Hello, I'm trying to figure out how to identify the calling database within a sproc on a different database without using a parameter. Any ideas?
Thanks

Hi First Kit Carson,
Regarding your description, are you looking for something as below?
CREATE DATABASE TestDB1
CREATE DATABASE TestDB2
GO
USE TestDB1
CREATE TABLE TestDB2.dbo.T1(ID INT);
CREATE TABLE TestDB2.dbo.T2(ID INT);
GO
CREATE PROC dbo.PROC1
AS
SELECT * FROM TestDB2.dbo.T1
GO
CREATE PROC dbo.PROC2
AS
SELECT * FROM TestDB2.dbo.T2
GO
SELECT *
FROM sys.dm_sql_referenced_entities ('dbo.PROC2', 'OBJECT');
SELECT R.SPECIFIC_CATALOG,r.SPECIFIC_NAME,cat.* FROM
INFORMATION_SCHEMA.ROUTINES R
CROSS APPLY
SELECT referenced_server_name,referenced_database_name,referenced_schema_name,referenced_entity_name,referenced_minor_name,referenced_class_desc
FROM sys.dm_sql_referenced_entities(R.SPECIFIC_SCHEMA+'.'+R.SPECIFIC_NAME,'OBJECT')
) AS cat
WHERE R.ROUTINE_TYPE='PROCEDURE'
GO
USE master
DROP DATABASE TESTDB1,TESTDB2
If you have any question, feel free to let me know.
