IDRoleApps and ViewName together is fine.


CREATE TABLE [dbo].[ViewName](
      [IDViewName] [bigint] IDENTITY(1,1) NOT NULL,
      [ViewName] [nvarchar](50) NOT NULL,
      [ViewType] [nvarchar](50) NOT NULL,
      [ViewDescription] [nvarchar](255) NOT NULL,
      [IDRolesApps] [bigint] NULL,
 CONSTRAINT [ViewName_PrimaryKey] PRIMARY KEY CLUSTERED
(
      [IDViewName] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY],
 CONSTRAINT [IDViewName] UNIQUE NONCLUSTERED
(
      [ViewName] ASC,
      [IDRolesApps] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY],

It appears to be added as a Unique Index and without a name supplied by the code. I suspect it will have a system generated name which you will have to retrieve and  then use to drop the Indie (or possibly a constraint).

Do you have access to the database itself via SSMS?

OK, open the table in design, right click in and empty part of the designer and choose Indexes.

Review those list - lick each in turn on the left and see which fields are included in the right hand panel. The names on the left are the Index (or constraint names). You can delete it there by selecting it and deleting or using the syntax

ALTER TABLE tablename DROP CONSTRAINT indexname

It is a shared db so can see the design but cannot interact or modify it.

Alter table commands would work.

OK, use the management studio to see the index as described above, then use the name in the statement supplied above.
