In SQL Server 2000 or above is there anyway to handle an auto generated primary key (identity) column when using a statement like the following?
Insert Into TableName Values(?, ?, ?)
My goal is to NOT use the column names at all.
This question is related to

identity
The best practice is to explicitly list the columns:
Insert Into TableName(col1, col2,col2) Values(?, ?, ?)
Otherwise, your original insert will break if you add another column to your table.
Another "trick" for generating the column list is simply to drag the "Columns" node from Object Explorer onto a query window.
set identity_insert customer on
insert into Customer(id,Name,city,Salary) values(8,'bcd','Amritsar',1234)
where 'customer' is table name
Since it isn't practical to put code in a comment, in response to your comment in Eric's answer that it's not working for you...
I just ran the following on a SQL 2005 box (sorry, no 2000 handy) with default settings and it worked without error:
CREATE TABLE dbo.Test_Identity_Insert
(
id INT IDENTITY NOT NULL,
my_string VARCHAR(20) NOT NULL,
CONSTRAINT PK_Test_Identity_Insert PRIMARY KEY CLUSTERED (id)
)
GO
INSERT INTO dbo.Test_Identity_Insert VALUES ('test')
GO
SELECT * FROM dbo.Test_Identity_Insert
GO
Are you perhaps sending the ID value over in your values list? I don't think that you can make it ignore the column if you actually pass a value for it. For example, if your table has 6 columns and you want to ignore the IDENTITY column you can only pass 5 values.
You have 2 choices:
1) Either specify the column name list (without the identity column).
2) SET IDENTITY_INSERT tablename ON, followed by insert statements that provide explicit values for the identity column, followed by SET IDENTITY_INSERT tablename OFF.
If you are avoiding a column name list, perhaps this 'trick' might help?:
-- Get a comma separated list of a table's column names
SELECT STUFF(
(SELECT
',' + COLUMN_NAME AS [text()]
FROM
INFORMATION_SCHEMA.COLUMNS
WHERE
TABLE_NAME = 'TableName'
Order By Ordinal_position
FOR XML PATH('')
), 1,1, '')
