BULK insert with FIRE_TRIGGERS not execute the trigger

Question

I am using the following code to Bulk insert a CSV file:

    BULK
INSERT CustomSelection
FROM \'c:\\asd\\a1.csv\'
WITH
(
FIRSTROW =2,
FIELDTERMINATOR = \',\'         


        

Answer 1

During a bulk-import operation, your trigger will be fired only once because it's considerated as a single statement that affects multiple rows of data.

Your trigger should be able to handle a set of rows instead a single rows. Maybe this is the reason because your manual insert test is working fine and your bulk import is failing.

The C section of this MSDN article, show you how to create an insert trigger to Handle Multiple Rows of Data: http://msdn.microsoft.com/en-us/library/ms190752.aspx

Hope it helps.
