How to Trace Executed Queries

  • I need to know which queries are being executed and what modification each performed on tables. Is there any tool to handle this?

  • hi

    try using the stored proc 'exec sp_trace_setstatus

    manz

  • so far as I know it sets status of a server side trace.

    maybe I've not asked my question clearly; I need history of data changes and the queries that performed those changes

  • You can have following options:

    1. DML Trigger

    2. C2 Auditing

    3. Profiler to capture the desire DML transactions.

    Before implementing the above options you need to understand the objective and find out why and what you want? As C2 auditing and profiler is highly resource consuming process.

  • In addition to the suggestions above, it's worth noting that SQL Server 2008 offers Change Data Capture, another way to monitor what was changed in the data.

  • Just run a trace

    [font="Comic Sans MS"]+++BLADE+++[/font]:cool:

  • peace2007 here is what i use.

    it is a stored procedure i wrote, which creates a trace.

    It creates a trace and a view in the MASTER database; it includes a lot of information, so you can see the DML statements, as well as performance indictors to see if any given statement was slow or fast.

    it also creates a VIEW, so i can see the results of the trace on demand.

    the viewname starts with sp_ so I can call it from anywhere:

    select * from sp_DMLTrace

    and I can review the trace at my leisure.

    see if this might help you in the future:

  • Thank You 🙂

  • It sounds to me like you're still trying to answer the main question for yourself, especially since in a lot of ways you're asking two different questions: what queries are being executed, and what data modifications are taking place.

    How often do you need to know what queries are being executed- daily, only in specific circumstances, is there a specific triggering event? Depending on the load on your databases, any kind of logging may quickly overload you with too much information.

    When data modifications are taking place, how often do you need to see what actually happened? Is there a legal requirement that must be satisfied? How long will you be required to keep any documentation of this kind?

    There are lots of really good articles that talk about both of these topics; if I were you, I would first start by narrowing down what I was trying to accomplish by setting some very specific targets.
