Simplified Syntax for Scala 3

Anshika Agrawal shows a few examples of how Scala 3 is a bit easier to pick up than Scala 2:

Scala 3 is a remodel/refit for the scala language. It attracts developers due to its improved features such as simpler syntax, better type inference, improved error messages, and enhanced support for functional programming. In this article, we will compare the syntactical enhancement of Scala 2 & Scala 3. How indentation will help developers to write code efficiently and effortlessly.

Click through for some examples. On the whole, these are small but welcome changes in eliminating unnecessary code cruft.

SOUNDEX in Snowflake

Kevin Wilkie makes a noise:

In Snowflake, there is another function that is SOUNDEX-like that can give slightly different results – SOUNDEX_P123.

For those cases where the first and second letters of the string have the same SOUNDEX number, the SOUNDEX_P123 function will keep the number for the second letter. This variant is used in a few other database systems, for example, Teradata.

Click through for a demonstration of the two SOUNDEX() variants and how results can differ.

Reviewing Database Usage Trends

Brendan Tierney looks at the data:

Getting back to the topic of this post, I’ve gathered some data and obtained some league tables from some sites. These will help to have a closer look at what is really happening in the Database market throughout 2022. Two popular sites who constantly monitor the wider internet and judge how popular Databases area globally. These sites are DB-Engines and TOPDB Top Database index. These are well know and are frequently cited. Both of these sites give some details of how they calculate their scores, with one focused mainly on how common the Database appears in searches across different search engines, while the other one, in addition to search engine results/searches, also looks across different websites, discussion forms, social media, job vacancies, etc.

I don’t necessarily believe that these are totally accurate, though on the whole, I do expect the results to be directionally accurate. I’ve used DB-Engines data several times in the past and like to point out that, for any given year, 7 or 8 of the top 10 database engines are relational.

Restoring a TDE Database Sans Certificate

Matthew McGiffen helps us recover from a big oopsie:

If you don’t have the backups of the certificate and private key from the old server, as well as the password used to encrypt the private key backup then you could be in a lot of trouble. There is one scenario where you have a way out. I’m going to assume you don’t have the possibility to recover your old server from a complete file system backup – if you do then you can do that and access all the keys you require. If the two following things are true though then you can still recover your database:

Read on to see what those requirements are and how you can, in specific circumstances, recover that database.

Sessions and Execution of Dynamic SQL

Deborah Melkin riddles us this on dynamic SQL:

I admit it – I do waaayyyy too much with dynamic SQL. But I just keep running into situations that require it. That being said, I ran into an interesting problem that had me puzzled. I found a bunch of different blog posts that pointed to me to the right direction but required a little extra work to find the solution.

There are several concepts that are at play here, so I’ll try to break this out so we can put the pieces together. The first once is centered around dynamic SQL. There are two parts of this I want to make sure we understand first – how it fits into sessions and how it gets executed.

Configuring Ola’s Scripts

Ben Miller begins a series on Ola Hallengren’s maintenance solution:

I recommended creating a database to use for this solution or even installing it into an existing DBA function database. I usually create a DBA database and use it for this purpose and others as well. With this new database, you configure the Database in the header of the maintenance solution SQL file, whether to create jobs, retention time and backup directory for the jobs.

This first post acts as a primer for those who might have the solution but haven’t investigated it in any detail.

Java Licensing Changes Upcoming

Lindsay Clark covers an upcoming licensing change:

Industry experts have pointed out that businesses with limited Java use would have to license the software per employee under the new model, a dramatic shift from the one Oracle previously afforded them.

This week, Big Red – which acquired Java with its buyout of Sun Microsystems in 2009 – said the new Java SE Universal Subscription is “a simple, low-cost monthly subscription that includes Java SE Licensing and Support for use on Desktops, Servers or Cloud deployments.”

Seems like as good a reason as any to kick the Java habit.
