Stored procedures in SSIS Packages

We are doing a huge Data Migration Project using SSIS packages. We were insisted on not using stored procedures in SSIS packages. Can you please suggest whether we should be using stored procedures in SSIS packages or not? What are the开发者_运维百科 advantages of using stored procedures?

It is correct that merge statements can easily be used in SSIS and your directive to encapsulate everything in SSIS is not necessary, as SQL processing aggregations faster than SSIS, for example. Further, if you are not deploying to SSISDB or have proper logging wrappers or email alerts, then troubleshooting your ETL is going to be more difficult via the SQL agent than otherwise as the errors are frequently more cryptic - thus the SSISDB and its reports in 2012. SSIS can be extremely powerful, however.

Here is a fairly blatant benchmark that will tell you never to use the out of the box SCD ever in SSIS. Taskfactory however does have a nice deployable which does basically merges behind the scene.

SSIS has more powerful functions than Stored Procedures. However you can easily use Execute T-SQL Statement tasks in SSIS for existing tasks, and then build out from there.

• SSIS is superior at the vast majority of ETL

1. Microsoft Integration Services is a platform for building enterprise-level data integration and data transformations solutions. You use Integration Services to solve complex business problems by copying or downloading files, defining business logic, sending e-mail messages in response to events, updating data warehouses, cleaning and mining data, and managing SQL Server objects and data. The packages can work alone or in concert with other packages to address complex business needs. Integration Services can extract and transform data from a wide variety of sources such as XML data files, flat files, and relational data sources, and then load the data into one or more destinations.

Integration Services includes a rich set of built-in tasks and transformations; tools for constructing packages; and the Integration Services service for running and managing packages. You can use the graphical Integration Services tools to create solutions without writing a single line of code; or you can program the extensive Integration Services object model to create packages programmatically and code custom tasks and other package objects.

2. A stored procedure in SQL Server is a group of one or more Transact-SQL statements or a reference to a Microsoft .NET Framework common runtime language (CLR) method. They can be called from within SSIS just the same as the unencapsulated SQL statement. For more information about it, please see: http://msdn.microsoft.com/en-us/library/ms190782(v=sql.110).aspx
