SQL Server Maximum Stored Procedure Limit issue

Question

I'm getting the following error after creating a trigger in SQL Server, i have researched this error and tried so many different things but nothing has worked.

Microsoft OLE DB Provider for SQL Server error '80040e14' Maximum stored procedure, function, trigger, or view nesting level exceeded (limit 32)

USE [admin_W4F]
GO
/****** Object:  Trigger [lee2121].[discount]    Script Date: 6/7/2019     10:45:55 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER TRIGGER [lee2121].[discount]
ON  [lee2121].[Cart]
AFTER INSERT,DELETE,UPDATE
AS 
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

update [lee2121].Cart
set totalprice2 = [lee2121].[Cart].[price] - ([lee2121].[Cart]. [price]/[lee2121].[Cart].[disc])

END

Answer 1

Don't use a trigger for this! Just use a computed column:

alter table [lee2121].[Cart]
    add totalprice2 (price - (price / disc);

The value will be calculated when the table is queried. The values will always be up-to-date.

Answer 2

It looks like your trigger is firing your trigger? Try adding NOT FOR REPLICATION

Answer 3

so in the end i have gone with a computed column which seems to be working fine, i used this code;

([price]-[price]/[disc])

Thank you.
