Below is sample code to create a table within DTS. Every time I use such
code, I have to manually edit each table created and set the primary key
field to be an identity type.

Can I change the code below on the causeID field to make it an identity type
with code?



CODE:

CREATE TABLE [myDatabase].[dbo].[myTable] (
[causeID] int NOT NULL,
[causeCode] varchar (3) NULL,
[causeName] varchar (50) NULL
)

Given fact that the table has identity or primary key field data, how will
this effect existing values? will it reset the 1st record causeID to "1" or
will it maintain the primary key values and just allow the causeID field to
be an identity type?

Is this what you want:


CREATE TABLE [myDatabase].[dbo].[myTable] (
[causeID] int IDENTITY(1,1) NOT NULL,
[causeCode] varchar (3) NULL,
[causeName] varchar (50) NULL
)

Hi,

See the syntax:-

CREATE TABLE [myDatabase].[dbo].[myTable] (
[causeID] int IDENTITY(1,1) NOT NULL constraint pk_causeid Primary Key,
[causeCode] varchar (3) NULL,
[causeName] varchar (50) NULL
)
