Intelligent Conditional Split in an SSIS Package

Conditional Split is one of the most commonly used transforms in any SSIS Package development routine. The limitation with conditional split is that any record that satisfies the first condition from the conditions list is routed to its corresponding path exclusively. In a logical sense, a record might satisfy more than one condition and one might want the record to be routed to all paths for processing, but with the Conditional Split transform this is not possible. We need a more intelligent conditional split where we can selectively route the records to more than one output path. In this tip we will look at how to facilitate this intelligent conditional split.

Can I really drop that index?

You believe that an index is unused and so could be removed, and yet, your finger hovers nervously over the metaphorical "delete" button. You can't quite bring yourself to do it. Is it really safe to drop this index? Tony wonders if "invisible indexes" might solve this dilemma.

Get Out The Vote

It’s actually kind of cool that SQL Rally voting for the pre-conference seminars and voting in the real(ish) world in the USA are coinciding. I’m in the running for the pre-con AND I’m volunteering for an actual election campaign for the first time ever.

Question of the Day

Getting the Average

I have this data in the dbo.Commission table in a SQL Server 2022 database. 

salesperson commission
Brian       12
Brian       16
Andy        7
Andy        14
Andy        21
Steve       20
Steve       NULL
All the data is a varchar, and I decide to run this query to get the totals for each salesperson. 
SELECT SalesPerson
     , AVG(TRY_PARSE(Commission AS int)) AS TotalCommission
 FROM commission
 GROUP BY SalesPerson
GO
What average commission is calculated for Steve?
