how to trace SQL table drop create events - sql-server

Question

I have some mysterious problem where every day one table in DB (SQL Server 2016) is being recreated (I suppose dropped and created) with old data. I checked various options to try to find what process is doing this, however was unable to do that.
Scheduled Tasks - nothing
SQL Agent Jobs - nothing
How to trace what user/application/anythingelse is doing this ?
I tried launching SQL Profiler and starting manual trace, but after some time (half a day or so) it just stopped.

Answer 1

The default trace captures schema changes. Review the Schema Change History report or run the query below to retrieve the info in T-SQL. Note that the default trace rollover files are limited to 5 files of up to 20MB each so older events may have rolled off.
--select object created and deleted information from default trace
SELECT
trace_table.StartTime
, te.name
, trace_table.ObjectName
, trace_table.ApplicationName
, trace_table.LoginName
FROM (
SELECT REVERSE(SUBSTRING(REVERSE(path), CHARINDEX('\', REVERSE(path)) , 255)) + 'log.trc'
FROM sys.traces
WHERE
is_default = 1
) AS trace(path)
CROSS APPLY sys.fn_trace_gettable(trace.path, DEFAULT) AS trace_table
JOIN sys.trace_events AS te ON
te.trace_event_id = trace_table.EventClass
WHERE
EventSubClass = 0
AND name IN('Object:Created', 'Object:Deleted')
ORDER BY StartTime;

create a database trigger and log the create/drop table events:
create table dbo.traceTabledropcreate(EventDataXML xml, LogDatetime datetime default(getdate()));
go
create or alter trigger dbtrigger_traceTabledropcreate
on database
with execute as 'dbo'
for CREATE_TABLE, DROP_TABLE
as
begin
set nocount on;
--insert into dbo.traceTabledropcreate(EventDataXML)
--values (EVENTDATA());
declare #sessionxml xml =
(
select EVENTDATA(),
(
select *
from sys.dm_exec_sessions
where session_id = ##spid
for xml path('sessioninfo'), type
)
for xml path('')
);
insert into dbo.traceTabledropcreate(EventDataXML)
values (#sessionxml);
end
go
---..... and wait....
--..test
create table dbo.testtable(id int)
go
select *
from dbo.traceTabledropcreate
go
drop table dbo.testtable
go
select *
from dbo.traceTabledropcreate
go
