## Here is my script to alter a column in table:-

USE [HIS-MGMT-Subset]
GO

BEGIN TRANSACTION

DECLARE @ER int

ALTER TABLE [objects]
ALTER COLUMN ISBN nvarchar(450);

Select @ER= @@error
if @ER <> 0
BEGIN
ROLLBACK TRANSACTION
RETURN
END
COMMIT TRANSACTION

GO
--ROLLBACK TRANSACTION

## Error ouput:-

ALTER TABLE failed because the following SET options have incorrect settings: 'QUOTED_IDENTIFIER'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or filtered indexes and/or query notifications and/or XML data type methods and/or spatial index operations.

Please let me know what I need to do to execute the script

You've probably got a Computed Column in that table. Need to SET QUOTED_IDENTIFIER appropriately for that (and IME I've had similar trouble with any VIEWs on that table that have indexes, or somesuch that I have now forgotten). It may be irrational, but we avoid computed columns in tables for that reason

You should always have these settings in place when acting against any SQL object:

SET ANSI_NULLS ON
SET QUOTED_IDENTIFIER ON
GO
ALTER TABLE ...
