问题 I am using SQL Server 2012. I want to create a row_number based on whether the index in subsequent rows are increasing by 1 or more. For example, say I have a table that looks like: event row_index 1 24 2 25 3 26 4 30 5 31 6 42 7 43 8 44 9 45 Then what I want to do is create a column at the end, called seq_ID: event row_index seq_id 1 24 1 2 25 1 3 26 1 4 30 2 5 31 2 6 42 3 7 43 3 8 44 3 9 45 3 basically, the seq_id only chances if the difference between subsequent row indexes is > 1. I have

However, I would like to upgrade these to 2012 via SQL Server Data Tools for Visual Studio 2012 which is easy enough, however, the company that I work for does not have any plans to upgrade the SQL Server to 2012 any time soon. So is there a way to create SSIS packages using SSIS 2012 and deploy them to a SQL Server 2008R2 instance while maintaining all of

问题 I'm trying to invoke an SSIS package in SQL Server 2012 (local installation) via a WCF service hosted in local IIS. The WCF Service is using tcp binding and the IIS app pool is running under NETWORKSERVICE. I'm using a console application to test the WCF service. After the console application calls the WCF service, the WCF service attempts to invoke a SSIS package on the local SQL Server and throws a "System.Data.SqlClient.SqlException: Login failed for user 'MYDOMAIN\MYMACHINENAME$'."
