SELECT tc.category_id AS CategoryId,ĬROSS APPLY (SELECT DISTINCT eventid FROM fn_trace_geteventinfo(t.id)) tei This query will list all 34 events captured by this trace. EXEC sp_configure 'show advanced options', 1ĮXEC sp_configure 'default trace enabled', 1 ĭefault trace collects details of 34 events and stores them in the *.trc files in default SQL Server Instance Log directory.
If it is disabled it can be easily enabled using sp_configure. You can also see that it is configured to have a maximum of 5 rollover files 20 megabytes each. You can very easily check if it is running on your instance using this simple query: SELECT * FROM sys.traces WHERE is_default = 1 It is an internal, server-side SQL trace which as the name suggests is created and enabled by default on every SQL Server instance. Default Trace was introduced in SQL Server 2005. The first and probably the easiest way to use is the Default Trace. I will use this as an example of changes that may be executed in one of your environments. USE master ĪDD CONSTRAINT pk_NewTable PRIMARY KEY CLUSTERED (Id) ĬREATE INDEX ix_NewTable_Col1 ON dbo.NewTable (Col1) ĭROP INDEX ix_NewTable_Col1 ON dbo.NewTable As a next step, I modify the procedure, the trigger, and the function. In this test, I create the following database objects: database, table, constraint, index, trigger, function, procedure, temporary table. To demonstrate you the advantages and drawbacks of various database schema change logging methods I prepared a very simple test case.

Today’s post describes how to use Default Trace. Thanks to this, you always will be able to easily answer such questions. In this short 5 part series, I will demonstrate you 5 different ways to track such database schema changes. What modifications were applied to the XYZ object?.In such a case, various questions arise and you as a DBA will have to answer some of them. They simply may be implemented in an inefficient way or even just be stupid. They may block deployment of next changes. They may break some functionality or create some other issues (ie. Sooner or later such unexpected schema changes start to be very problematic. However, it also may happen in higher level environments where only limited number of people have access (the rare case – but not impossible). It may happen in a development environment where a bunch of people have access and deployment process is not very strict (the common case). Unfortunately, we don’t live in the perfect world…ĭespite the version control system, change management process, and limited access to the server, sometimes database schema is changed without our knowledge and supervision.

The database schema is stored in a source code repository and deployed version doesn’t drift unexpectedly from its original model. All database schema changes go through strict Change Management Process where they need to be well described and approved by Change Advisory Board. In the perfect world, only Database Administrators have access to SQL Server databases.
