Question

I’ve never created a trigger before and I’m trying to read online but am a little confused.

I want to create a trigger on a table that on insert, it will grab some data from different columns and insert it into a few different other tables.

I’m not sure how to write the T-SQL to get the data from the columns..

insert into [othetTable] 
values ([col1 from row that was inserted], [col5 from row that was inserted])

What would the syntax be to get those values?

thanks

Answer 1

Use the inserted virtual table that is available to triggers. Note that there could be multiple rows in this table – your trigger could be processing multiple inserts at once.

Therefore, you need to use something like the following syntax:

insert into othertable
select col1, col5
from inserted

This will insert a row into othertable for each inserted row.
