Not sure if I am asking the right question but would it be possible to run the below code so when information in my tables is updated the code below automatically runs?

DELETE FROM Funnel;

INSERT INTO funnel
SELECT [Q2_MetMin].*
FROM Q2_MetMin;

INSERT INTO funnel
SELECT [Q3_RecApp].*
FROM Q3_RecApp;

yep.. you can add this code in a procedure and call it from scheduled sql agent job. the preceding step should be the one which updates information in your tables. The job can then be scheduled as per your required schedule

Yes it would be a trigger.
What do you want to fire the trigger though?
I'm guessing it would be an update to Q2_MetMin or Q3_RecApp? That might mean a trigger on each of those tables.
This might be an issue because if someone does single row updates then the data in funnel would be deleted and inserted for each row.
You might want to consider a trigger that uses the PK of the row updated in the source tables to minimise the activity.

==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

Yes I would want the updates in Q2_MetMin to fire the trigger. How do I write the correct syntax?
