TSQL query to find un-used stored procedures

Question

I am trying to track down all stored procedures in a database that have never been used, or that have not been used in many months.

I would like to find a query to s

Answer 1

For some reason, my dm_exec_procedure_stats view clears itself out through the day. So I just ran it right now and the earliest execution times are from this morning, but I know we didn't restart SQL this morning or anything.

Anyway, I wanted to create a proc that I could put into a job to run every hour and capture which procs had run recently. Here is what I did:

Created a table to log the procs that get executed and their first and last execution times.

create table ProcsThatExecute (procName varchar(500), firstExecutionTime datetime, lastExecutionTime datetime)

Created a procedure that inserts or updates the ProcsThatExecute table. Run this every hour in a job and after a few days or weeks or months you have a log of which procs get used:

alter procedure LogProcsThatExecute as begin

    --If they don't already exist in this table, add them.
    insert into ProcsThatExecute(procName, firstExecutionTime, lastExecutionTime)
    SELECT p.NAME ProcName, s.last_execution_time, null
    FROM sys.procedures AS p
        LEFT OUTER JOIN sys.dm_exec_procedure_stats AS s ON p.[object_id] = s.[object_id]
    where not exists (
        select 1 from ProcsThatExecute pte where pte.procName = p.name
    ) and last_execution_time is not null


    --If they do exist in this table, update the last execution time.
    update ProcsThatExecute set lastExecutionTime = s.last_execution_time
    from ProcsThatExecute pte
    inner join sys.procedures AS p on pte.procName = p.name
        LEFT OUTER JOIN sys.dm_exec_procedure_stats AS s ON p.[object_id] = s.[object_id]
    where s.last_execution_time is not null

end
