INSERT INTO "part" (
You select statement is generating a result set and you have not 'stored' it anywhere - i.e. you need to put it into a temporary table (or a variable if the result set is a single row). You need to do this because a result set cannot be propagated outside of the trigger.
Put another way: A trigger cannot generate/propagate a result set.
From the comment in the code it looks like you are trying to assign @count with a value ... but I do not know which value you want to assign it with. See the documentation on the SELECT statement, and in particular the "INTO clause".
Fix the select statement and your problem will be fixed.

New_part.product_code exists in the new_part.product_code,if there do not exist then not
