Just another way to prove the fact that logon trigger can fire up multiple times:

Earlier in the year, I explored how SSMS has the potential to open up multiple connections to the SQL Server – http://beyondrelational.com/blogs/nakul/archive/2011/01/17/the-multiple-connections-of-ssms.aspx

Because there are multiple connections being established, multiple logins have to take place and therefore the login trigger has to be fired multiple times (once per connection).

[...] It happens because multiple SQL Server services are running and also as intellisense is turned on. (Read more here) [...]

Hi Pinal,

I am using SQL Server 2005 and trying with the trigger query but when ever I am trying to execute the trigger statement it states “LOGON’ is an invalid event type.

Hello Prasad,

you have bounded these two tables in such a way that there is no point to insert the first records.
To insert records in these table at least one condition must be fulfilled:
1. Allow null in foreigk key column in any one table
2. Alter the foreign key constraint to NOCHECK in any one table
3. At least one record exists in any one table.

Kind Regards,
Pinal Dave

thanks for answer, but why intellisense ? it has nothing in common with logon trigger, or maybe I`m wrong…
