Long Short-Term Memory Network for Machine Learning

While Recurrent Neural Networks (RNN) are powerful, they often struggle with long-term dependencies due to the vanishing gradient problem. Long Short-Term Memory Networks (LSTMs) address this issue by introducing memory cells and gates. For beginners, understanding LSTM components, such as the input, output, and forget gates, can be challenging. This tip breaks down LSTMs in an intuitive way, highlighting their importance and practical applications.

Split strings by Regular Expressions in SQL Server 2025

SQL Server users have been asking for native regular expression support for over two decades. There are third-party Common Language Runtime (CLR) modules that offer this functionality, but these can be complicated to install and simply aren’t possible in some environments. I want to split a string using a regular expression instead of a static string. Will that be possible in SQL Server 2025, without CLR?

Missing the Jaro Winkler Distance

I upgraded a SQL Server 2019 instance to SQL Server 2025. I wanted to test the fuzzy string search functions. I run this code:

SELECT JARO_WINKLER_DISTANCE('tim', 'tom')
I get this error message:
Msg 195, Level 15, State 10, Line 1 'JARO_WINKLER_DISTANCE' is not a recognized built-in function name.
What is wrong?
