Searching Stored SQL – Part 3

There are four main database objects that contain stored SQL: VIEWS, TRIGGERS, FUNCTIONS and STORED PROCEDURES. Yesterday, I created a pattern searching tool for TRIGGERS. Today, I am going to clone and modify the code so that it will work with FUNCTIONS.

Again, I want to examine the dynamic SELECT statement that retrieves the user defined stored procedure names from a given database. This is the key element of the whole program.

I took the liberty to modify the original code so that it will work standalone. The current code returns the schema name, the object name, and a combination of both called full name. The full name is used by the system stored procedure called sp_helptext that returns the stored SQL code (text) for any object.

Both the sys.objects and sys.schemas system views are local to a given database. Therefore, the TSQL has to be dynamic since we do not know the database name ahead of time.

The WHERE clause has an expression that filters in the correct object type. I will substitute ‘P’ with (‘FN’ , ‘IF’, ‘TF’) for this code to search for FUNCTIONS. Please refer to books on line for object type in sys.objects. Both the global and local temporary table names are changed to reflect FUNCTIONS in our new procedure named [usp_get_text4fn].

Enclosed is the full stored procedure for your usage.

A sample call to the tool to list and save all function code in the AdventureWorks database to a user defined table.

We can filter by object name if it is known. I am looking for the user defined function called GetContactInformation.

We can filter by actual code if we know a key value. I am looking for any tables that have the word Inventory.

The image below show the results of this search. The first record matches a table that we were looking for. Unfortunately, the second match is only comments and is not important for our current research.

Again, the user defined table created by this procedure stays in the system until tempdb is recreated upon server startup. Next time, I will show how this query needs to be adjusted to display SQL code for VIEWS.
