Hello everyone, assuming I have a table called tabpeople and it has the fields: id (primary key auto increment), number (text) and name (text). How can I create a trigger that always after adding a person, the number field is updated to the same value as the id field with 5 leading zeros?

Thank you all.

What I have tried:

I tried to adapt some examples that I found but I could not do that.

Pleas try:

SQL

CREATE TRIGGER tabpeople_i 
   ON  tabpeople
   FOR  INSERT
AS 
BEGIN
SET NOCOUNT ON;
UPDATE t
	SET name='00000'+LTRIM(rtrim(str(i.id)))
	FROM tabpeople t
	JOIN inserted I 
		ON i.id=t.id

END
