I have 2 servers one for accounting and one for business activity (orders,qc,etc...) These are considered production systems... I also have a server for a test environment for the business activity, for accounting the test environment is another database on the production server...
I have the production servers linked and then the test server linked to production accounting but only the accounting test database (user security)..
I have a view in my business activity environment that displays addresses from the accounting system...
CREATE VIEW [dbo].[vw_accounting_address]
AS
SELECT
[Customer].[CustID] AS [accounting_entity],
[Customer].[CompanyID] AS [accounting_company],
[Customer].[CustName] AS [customer_name],
[Address].[AddrLine1] AS [address_line_1],
[Address].[AddrLine2] AS [address_line_2],
[Address].[City] AS [city],
[Address].[StateID] AS [region],
[Address].[CountryID] AS [country],
[Address].[PostalCode] AS [postal_code]
FROM
[accounting_server].[accounting].[dbo].[Customer]
JOIN [accounting_server].[accounting].[dbo].[CustAddr] ON [Customer].[CustKey] = [CustAddr].[CustKey]
JOIN [accounting_server].[accounting].[dbo].[Address] ON [CustAddr].[AddrKey] = [Address].[AddrKey]
I have the same view in my test environment, but using a different database...
CREATE VIEW [dbo].[vw_accounting_address]
AS
SELECT
[Customer].[CustID] AS [accounting_entity],
[Customer].[CompanyID] AS [accounting_company],
[Customer].[CustName] AS [customer_name],
[Address].[AddrLine1] AS [address_line_1],
[Address].[AddrLine2] AS [address_line_2],
[Address].[City] AS [city],
[Address].[StateID] AS [region],
[Address].[CountryID] AS [country],
[Address].[PostalCode] AS [postal_code]
FROM
[accounting_server].[accounting_test].[dbo].[Customer]
JOIN [accounting_server].[accounting_test].[dbo].[CustAddr] ON [Customer].[CustKey] = [CustAddr].[CustKey]
JOIN [accounting_server].[accounting_test].[dbo].[Address] ON [CustAddr].[AddrKey] = [Address].[AddrKey]
Is there anyway to remove the difference between the 2 views {accounting} vs. {accounting_test} so we do not always have to manually address these discrepancies when syncing production environments to test... This is not the only view we have like this... But if we were to change the view, we would make the change in the test environments and perform testing... Once testing is complete, we just take script and execute against production, but for these views we have to remember to change accounting_test to accounting... Curious to hear others thought and ideas on how to make view source exactly same in all environments and not require manual change or additional scripts to handle...

Hi Brian,

You can possibly use synonyms for all tables that you reference in views. If there are not too many of them, you could have one set of synonyms for test environment and another one on production. The code using them wouldn't change.

Use a linked server with the same name in test and production.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Is there something stopping you creating a seperate instance on the test server for the accounting database and linking to that? That way Live and Test would be on seperate physical servers and you could still set up the linked servers as you would in Live, if you were to do this though and the machines remained on the same domain I would recommend using different security accounts just incase! Thats not too difficult to code round when you promote the scripts through the environments.

I think I like the last advice. Mimic the production environment and keep the names the same. A linked server also works, but be sure you use different accounts in test and production just to be safe.
