Shortly after, various software vendors started to integrate with DBeaver (mostly as an extensions to their proprietary Eclipse RCP products: Zend Studio, NXTware, DeltaDNA, etc.). In 2012 an Eclipse plugin version was released - since then DBeaver has become one of the most popular database extensions for Eclipse (top 50-60 among all Eclipse extensions).
In the same year, the official web site was founded and the community support forum (now moved to GitHub) was created. It quickly became a popular tool in the open-source community. The first official release was in 2011 on Freecode.
It was supposed to be free and open-source with a good-looking and convenient UI and to include frequently used features for database developers. A closed-source enterprise edition of DBeaver is distributed under a commercial license.ĭBeaver was started in 2010 as a hobby project. The community edition (CE) of DBeaver is a free and open source software that is distributed under the Apache License. This is a desktop application written in Java and based on Eclipse platform. It provides a plug-in architecture (based on the Eclipse plugins architecture) that allows users to modify much of the application's behavior to provide database-specific functionality or features that are database-independent.
It provides an editor that supports code completion and syntax highlighting. For other databases ( NoSQL) it uses proprietary database drivers. For relational databases it uses the JDBC application programming interface (API) to interact with databases via a JDBC driver.

Case in point, the IIF function is only found in Microsoft products. As mentioned at the beginning of the series, it's helpful to know the exact function names and signatures for your specific database type because they can vary from provider to provider.
That brings us to the end of our series on the most important SQL Server Functions. If it returns a 1, it will be counted under that column heading (Short, Medium, or Long): Conclusion
We use the IIF() function to compare the length of the film to a given expression, and depending on the result, it returns a 1 or a NULL. We'll categorize film lengths as follows: We can utilize the IIF function to separate film lengths into three groups - Short, Medium, and Long - depending on their lengths. IIF(expression, value_if_true, value_if_false) SQL Server provides the power of the if/else statement to our queries in the form of the IIF function. If/else statements are the most commonly used control flow structures in programming. Here's a query that shows the same field in its original datetime format and without the time portion: IIF One good reason to use CONVERT is for removing the time portion from a datetime field. In SQL Server, you can change the data type of a value to another using the CONVERT function. We can employ COALESCE to set its value to 1 (the language_id for English) whenever a null is found: CONVERTĬonverting an output value into a specified data type is par for the course in database work. for example, the film table of the Sakila Sample Database contains a column named original_language_id for films that are not originally in English. In some instances a different value may make more sense. It is commonplace to substitute a value of zero in the place of null. Hence, SQL Server proceeds through each input parameter you provided until it either encounters one that isn't null or simply runs out of arguments. The COALESCE function accepts a list of arguments and returns the first one that does not contain a null value. Trouble is, nulls can reek havoc when included in calculations as well as other operations that one might perform on column data. That only makes sense, because null values represent absent or missing information. Far from leftovers, these functions are among some of the most useful you'll ever come across! COALESCEĪnytime you select a column whose value is not mandatory, you're bound to encounter null values. This last category of important SQL Server functions includes those that deal with nulls, conversion, and control flow.
