Additional Columns in StreamInsight Event Flow Debugger

  • Article

This tool is excellent when investigating what is going on in your StreamInsight Streams. I was looking through the menu items recently and went to Query => Event Fields I found that there were a couple of columns not added by default to the event viewer (Reminds me of the fact that the Variables viewer in SSIS hides columns also) Latency NewEndTime EnqueueTime Here they all are together.

Introducing Microsoft’s Platform for Complex Event Processing

  • Article

While typical relational database applications are query-driven, event-driven applications have become increasingly important. Event-driven applications are characterized by high event data rates, continuous queries, and millisecond latency requirements that make it impractical to persist the data in a relational database for processing. These requirements are shared by vertical markets such as manufacturing, oil and gas, utilities, financial services, health care, web analytics, and IT and data center monitoring. Event-driven applications use complex event processing (CEP) technology with the goal of identifying meaningful patterns, relationships and data abstractions from among seemingly unrelated events and trigger immediate response actions.

Question of the Day

Detecting Characters

I have a SQL Server 2022 English default installation on a server. I want to detect if there are any upper case characters in rows and I have this code: 

SELECT CustomerNameID,
       CustomerName
 FROM dbo.CustomerName
 WHERE CustomerName = LOWER(CustomerName)
Here is the sample data I am testing with: 
CustomerNameID CustomerName
1              John Smith
2              Sarah Johnson
3              MICHAEL WILLIAMS
4              JENNIFER BROWN
5              david jones
6              emily davis
7              Robert Miller
8              LISA WILSON
9              christopher moore
10             Amanda Taylor
How many rows are returned?
