What is '- Do'? You can't have that as part of an identity.

Solution 1

CREATE TABLE [dbo].[Customers] (
 [pk_ID] [int] IDENTITY NOT NULL ,
 [sValue] [char] (10) NULL ,
 [sDesc] [char] (10) NULL ,
 [iOrd] [numeric](18, 0) NULL 
) ON [PRIMARY]

Turn pk_ID for pk_ID=1 into 1, 001 - Do using string.Format

There is no such an identity field but you can use computed fields to achieve that output :

SQL

CREATE TABLE [dbo].[Customers](
     [pk_ID] [int] IDENTITY(1,1) NOT NULL,
     [sValue] [char] (10) NULL ,
     [sDesc] [char] (10) NULL ,
     [iOrd] [numeric](18, 0) NULL ,
     [cus_id]  AS (substring(CONVERT([varchar],(100000000000.)+[id],0),(2),(11))+' - Do') PERSISTED
) ON [PRIMARY]

Note :

1- PERSITED is important if you want to use cus_id in table relations
2- 11 is number of zeros in 100 billion. if you want another number, count its zeros and substitude 11 with it.
3- if you got ARITHABORT error when inserting rows to the table : right click your database in SSMS then select Properties then in options section set Arithmetic Abort Enabled to True.

And finally if it solved your problem do no forget to set this as an answer or vote it up :)
