List all columns referenced in all procedures of all databases

Question

Is there a way that I can get all the columns and tables referenced in all the stored procedures in all the databases in an instance? The output should be:

Answer 1

Here is yet another way to do this. This is very DIRTY but I like it. Why? Because I came up with it. Anyway it is using Dynamic SQL inside Dynamic SQL to insert dependency information into temp table that can be queried.

This can be modified into a SP that you can run from time to time to update dependencies information, also temp table can be changes to real table if you want to store it.

IF OBJECT_ID('tempdb.dbo.#SPDependencyDetails') IS NOT NULL
DROP TABLE #SPDependencyDetails

CREATE TABLE #SPDependencyDetails

 Or_Object_Database NVARCHAR(128)
,Or_Object_Name NVARCHAR(128)
,Ref_Database_Name NVARCHAR(128)
,Ref_Schema_Name NVARCHAR(128)
,Ref_Object_Name NVARCHAR(128)
,Ref_Column_Name NVARCHAR(128)
,Is_Selected BIT
,Is_Updated BIT
,Is_Select_All BIT
,Is_All_Columns_Found BIT
)
