Hi,

I am using SSMS to change a field in a table to an identity field. However, when I try to save the change it times out (I have set the timeout to 300 seconds, but that hasn't helped).

This is the error:

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

This is the table definition:

USE [BPOptical]
GO
/****** Object:  Table [dbo].[payments]    Script Date: 04/23/2008 09:37:57 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[payments](
	[ipaymentid] [int] NOT NULL,
	[dpaid] [datetime] NOT NULL,
	[ipatientid] [int] NOT NULL,
	[ipaytypeid] [int] NOT NULL,
	[namount] [numeric](9, 2) NOT NULL,
	[cchequeno] [char](10) NOT NULL,
	[ddeposited] [datetime] NOT NULL,
	[cpostref] [char](10) NOT NULL,
	[creceiptno] [char](10) NOT NULL,
 CONSTRAINT [PK_payments] PRIMARY KEY NONCLUSTERED 
(
	[ipaymentid] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY],
 CONSTRAINT [UQ_payments] UNIQUE NONCLUSTERED 
(
	[creceiptno] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO
SET ANSI_PADDING OFF

There are only 1445 records in the table. Any ideas why this change times out?

Thanks

Frank.
