If you think there's actual evidence that I really am biased, let me know. Red tape means delays and delays sap everyone's energy and enthusiasm and suppress innovation. It can also be negative, which may seem counterintuitive until you remember that the word "ago" exists. Unlike commercial software vendors, whose support functions are secondary to their main business of selling products, these organisations live or die by the quality of the support they provide, so it is very good.). As far as I can tell, you just can't do this using an MS SQL Server custom aggregate. Manageability and ergonomics are critically important. In MS SQL Server, a CREATE PROCEDURE statement cannot appear halfway through a batch of SQL statements. It makes packaging up all your stuff into one place harder and more error-prone. If you're lucky, he knows the secret handshakes and isn't confused by it. But any one of them can emulate any calculation a GPU can perform.). Fancy running a SVM from scikit-learn or some arbitrary-precision arithmetic provided by gmpy2 in the middle of a SQL query? (Update: a couple of days after I published this, Microsoft made me look like a prat by announcing that it was open-sourcing .NET. Over the years I have discussed the issue of PostgreSQL vs. MS SQL Server many, many times. Azure Database for PostgreSQL Fully managed, intelligent, and scalable PostgreSQL; Azure SQL Managed Instance Managed, always up-to-date SQL instance in the cloud; Azure Database for MySQL Fully managed, scalable MySQL Database; SQL Server on Virtual Machines Host enterprise SQL Server apps in the cloud It all just works.). I and my colleagues freely move code and database dumps between them. Sometimes you have to create classes to store the data you are querying, which means knowing at compile time what that data looks like. DB2 vs PostgreSQL vs SQL Server Brent Ozar: Two Important Differences Between SQL Server & PostgreSQL Dr. Dewitt also has a great video about query optimization. This is not a metaphysico-theologico-philosophical statement, but a hugely useful semantic construction. Also, needless to say, "the author of PostgreSQL" is as meaningless as "the author of MS SQL Server". It is hopelessly unrealistic to expect to learn everything you will need to know up front. The logs themselves are human-readable and machine-readable and contain data likely to be of great value to a sysadmin. Its supporting IT infrastructure, the Worldwide LHC Computing Grid, is the world's largest computing grid. A few of the modules don't even do anything except provide templates to allow developers and advanced users to develop their own extensions and custom functionality. PGAdmin is cross-platform. We compound the interest on the 1st of every month. Sometimes these problems cause a late night or a lost weekend for the user; sometimes they cause missed deadlines and angry clients; sometimes it goes as far as legal and reputational risk. Note that by "support" I mean "help getting it to work properly". This is elegant and useful. Sad but true: some database programmers I know recently spent a lot of time and effort writing Python code which "sanitises" CSV in order to allow MS SQL Server to import it. The back-end database of Skype (ironically now owned by Microsoft) is PostgreSQL. You can use it over an SSH connection, even a slow one. ProKB is a Windows-based, OpenEdge application that allows you to browse a snapshot of the Progress Knowledge Base offline. They can take the special values infinity and -infinity. There's another thing though: psql. You may need to download version 2.0 now from the Chrome Web Store. using multithreading or special CPU instructions - stuff the database itself is not suitable for. Because the data is well-formatted CSV, it is trivially easy to visualise or analyse it in R or PostgreSQL itself or Python's matplotlib or whatever you like. On the two occasions I have asked the PostgreSQL mailing list for help, I have received replies from Tom Lane within 24 hours. Naturally, determining this is trivially easy in PostgreSQL – in fact, the most time-consuming bit is creating a table with 50 columns to hold the data. MS SQL Server feels like it was written by people who never have to actually use MS SQL Server to achieve anything. This engine is stable, feature-packed and, Even better, PL/V8 supports global (i.e. Long gone are the days when ASCII was universal, "character" and "byte" were fungible terms and "foreign" (from an Anglocentric standpoint) text was an exotic exception. This is in keeping with the general theme of PostgreSQL giving you all the tools you need to actually get things done. PostgreSQL supports $$ string quoting, like so: This is extremely useful for generating dynamic SQL because (a) it allows the user to avoid tedious and unreliable manual quoting and escaping when literal strings are nested and (b) since text editors and IDEs tend not to recogniise $$ as a string delimiter, syntax highlighting remains functional even in dynamic SQL code. Apologists for MS are quick to point out that this is unlikely because it would require the data to contain something outside Unicode's basic multilingual plane. More than 27,000 respondents gave us their user profile information. At worst, something else in your toolchain will break badly and you'll have a disaster on your hands. That being said, "MS SQL Server" is literally the most boring possible name for a SQL Server provided by MS. The reason large enterprises open-source their code and then pay their teams to continue working on it is because doing so benefits them.
