Not only data DATA PUMP WORK PROCESS

DDL triggers do not fire in response to events that affect local or global temporary tables and stored procedures. Can anybody post an example of an update trigger that accomplishes this successfully and in an elegant manner?

If your audit cannot be queried then it has no value. The text column of syscomments is limited to chars.

CREATE TRIGGER (Transact-SQL)

The inserted and deleted tables for a specific trigger contain rows that correspond only to the UPDATE statement that invoked the trigger. Change results to text and it will be formatted.

Wouldn’t it be better to insert a single row into the auid table? In this scenario, trigger T2 then fires and updates table T1. I had not thought of that, but it is a good idea: Database-scoped DDL triggers are stored as objects in the database in which they are created.

DDL triggers can be created in the master database and behave just like those created in user-designed databases. Don’t know if there are any obvious downsides? It’s undetermined – you’ll get one, arbitrary row – and you plainly ignore all others!!

The default configuration allows for nested triggers. For more information, see Use the inserted and deleted Tables. Member Jilby Feb This option is required for triggers on memory-optimized tables and is not supported for triggers on traditional tables. Great article Member Feb Use nvarchar maxvarchar maxand varbinary max instead.

Therefore, all messages originating inside the trigger that would typically reach the user, such as error messages and messages from the PRINT statement, are diverted to the SQL Server error log. Use the catalog views instead.

Use code generators You can’t have a single dispagadores to track all tables, you will need to generate similar but distinct triggers on each tracked table.

Then it joins the rows one row per column of the inserted and deleted tables by primary key and field name, and logs a line for each changed column. Enables you to control which user account the instance of SQL Server uses to validate permissions on any database objects that are referenced by the trigger.

Because CHECK constraints can reference only the columns on which the column-level or table-level constraint is defined, any cross-table constraints in this case, business rules must be defined as triggers.

Great Member Apr I was planning on using a trigger to do this, but after poking around on Google I found that it was incredibly easy to do this incorrectly, and I disparaxores to avoid that on the get-go.

Trigger conditions specify additional criteria that determine whether the tried DML, DDL, xisparadores logon events cause the trigger actions to be performed. In SQL Server 9.
