using metadata to identify which objects update my tables

May 6, 2015, 5:28 am

Hi we run 2008 std edition (I believe r2 on this server, will double check) and I need to find a needle in a haystack.

I am looking at two tables and would like to learn which, if any objects on same db updates these tables.   I'd even live with any references to these tables.  I already know sql agent is out of the picture.  I'm looking for a static approach, not a monitoring one because its possible updates don't occur till month end.

Is there a way in sql server to query the answer to such a question using dmvs or something like dmvs?   What if I get bold and want to search all db's on this server for objects that update my two tables even across dbs?

In the mean time, i'll look at scripting all triggers and procs , and doing a search on these table names in the scripts. 

I don't know that I've ever seen a way to script all triggers before.  Procs I can easily script from the object explorer details.  But I'm not sure if in explorer details--> server objects --> triggers does what I hope it does.

New 2014 Cardinality Estimator changes compile duration from nothing to infinity

June 25, 2014, 2:10 am
$
0
0

We have a data warehouse that we recently upgraded to 2014 (Enterprise).

Since the upgrade we are experiencing enormous compile times on most of our queries (2014 compatibility level only). Requesting an estimated execution plan can take up to half an hour where before it was as good as instantaneous. The execution time of queries improved in general by 30% but the long compilation times make this improvement useless.

We are experimenting with trace flags 2312/9481 to enable/disable the new CE and tweaking queries to figure out where the increase in time comes from. So far no success. If we disable the CE, compilation is fine, enabled, it is not.

Our statistics are up to date, indexes are in place and defragged, the databases are reasonably large (1-2 TB) and use a few column stores for fact-like tables. A typical query will use around 30 tables. We have identified some groups of tables with more or less the same cardinality. Our current theory is that SQL is trying to estimate each possible path (i.e. order of tables, join type, etc).

Our queries are generated and therefore we cannot influence them easily. They are also mostly unique. The queries use simple inner joins and the execution times are really good. It is the compilation time that is the problem.

So our question is basically, how can we influence the new CE/compiler in any way to;

- Have a maximum time to evaluate paths, i.e., be happy with a simpler plan if the better one takes forever to deduce.

- Figure out if there is any part of our queries (or structures) in particular that could be causing the problem.

- Figure out if there is a particular part of the query or phase of the compiler that is consuming the time.

Our "solution" at this moment is to disable the new cardinality estimator.

Any help is appreciated.

Cheers,
Michel

Hello

Has anyone been in a situation where their job title is "DBA/Developer"?If so what were the tasks associated for this "double" role?

Actually, I am in this situation - I got offered a job within my company as a DBA/Developer junior. The Developer role is quite clear- I know the scope of my work, but the problem is in the "DBA" role. I thought a minimum would to manage backup and restores...Of course it depends on the requirements of my organisation, but I'd just like to know what you all think

thank you in advance

Hi All.

I have a DB which uses FT and its SQL 2008 R2, unfortunately when the catalogue indexes are being rebuilt, this gets blocked by spid 43 which I believe is a system spid. Is there any reason why this is the case ?

Secondly, a catalogue which uses free text fails to display up to date information unless the catalogue index is rebuilt, is there any reason for this ?

Thanks in advance.

All,

When I create a new project and try to use the WSAT security tab, I get the following :

There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.

The following message may help in diagnosing the problem: Unable to connect to SQL Server database.

I am using VS2005 beta2 with a local copy of SQL Server Express.

I am new to all of this so a little help would be great

Thx

Deadlock on two delete statements

I have two store procedures running from different server.

  • Table 1 only has primary key on identity column plus column1.
  • SP1 
    setup transaction isolation level read uncommitted.
    there have delete statement for table 1 with where column1 and column2 meet criteria.
  • SP2
    just one delete statement from table 1 with where column1/column2/column3 meet criteria.

I am seeing the following deadlock graph. The SP1 always been selected as victim.  It looks like both side try lock the cluster index resource and waiting each other. Is that a way to solve this issue?
