I make a table with Default values and that works fine :
CREATE TABLE [TestDefault](
[ID] [int] NOT NULL,
[aInt] [int] NOT NULL DEFAULT ((0)),
[aTime] [datetime] NOT NULL DEFAULT (getdate()),
[aBit] [bit] NULL DEFAULT ((0)),
CONSTRAINT [PK_Logging.NotificationLog] PRIMARY KEY CLUSTERED
(
[ID] 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
But when I use "Script Table as" / Create To / New query Window then I get this :
USE [DB]
GO
/****** Object: Table [dbo].[TestDefault] Script Date: 21-5-2015 14:54:30 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[TestDefault](
[ID] [int] NOT NULL,
[aInt] [int] NOT NULL,
[aTime] [datetime] NOT NULL,
[aBit] [bit] NULL,
CONSTRAINT [PK_Logging.NotificationLog] PRIMARY KEY CLUSTERED
(
[ID] 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
ALTER TABLE [dbo].[TestDefault] ADD DEFAULT ((0)) FOR [aInt]
GO
ALTER TABLE [dbo].[TestDefault] ADD DEFAULT (getdate()) FOR [aTime]
GO
ALTER TABLE [dbo].[TestDefault] ADD DEFAULT ((0)) FOR [aBit]
GO
How do I get my original Defaults on the line of the ColumnNames ?

You can edit the script if you want them that way. SSMS scripts constraints separately to the table. Doesn't make much of a difference.

Thanks for your fast answer.

But I want to have the Default on the same line as the column because I have very much tables and columns.

It is easy to see them in one View.

The strange thing is, I have (by coincidence) a table which generates the script I want.

But I can not see any difference in properties or so in that table and column definition.

I am testing and looking around.

It is very strange I have very much tables and almost all tables generates the 'wrong'script.

But I have a few tables which are doing what I want !

And I found a difference :

SET ANSI_PADDING ON

GO

Does that make sense ?

Eureka !!

I found it myself.

If there is data in the table then the 'right' script will appear.

If there is no data in the table then the 'wrong' script be generated.

Thanks for looking with me.
