I wrote a gateway service that allowed an Oracle database server to talk to a SQL Server database server about two years ago in ColdFusion MX 6.1. Back then I was able to use a centralized auditing table to store all of the inserts and update values. At my current job I am writing a lot of stored procedures, and I wanted to do the same thing just in Transact SQL. In ColdFusion it is fairly easy to serialize complex data into a string using WDDX.
You can do something similar to this to serialize name value pairs in SQL.
DECLARE @myTable TABLE (myString NVARCHAR(128) NULL, myInt INT NULL, myBool BIT)
DECLARE @myXML XML
INSERT INTO @myTable
SELECT ‘My string’ AS myString, 12 AS myInt, 0 AS myBool
SET @myXML = (SELECT *
FROM @myTable AS myTable
FOR XML AUTO)
If you are using SQL Server 2005, you can store the XML value into a XML column or cast it into a NVARCHAR(MAX) or NTEXT column.
The result will look like the following;
