3/11/2024 0 Comments Alternative to scriptcaseThis means WHERE column = 'abc' returns TRUE only for values in the column exactly equal to 'abc'. Fortunately, though, this one is simpler.īy default, PostgreSQL performs a case-sensitive string comparison. It also differs a little based on the DBMS. Last but not least, let's talk about column values. If you’re new to SQL, we recommend reading the article “ 6 Common SQL Syntax Mistakes All Learners Make,” which helps you with the most common errors everyone gets at the beginning of the SQL journey. For this reason, you need to understand the error messages you can get. In MS SQL Server, the most common practice is to use PascalCase.ĭifferences in case sensitivity can lead to problems in executing your queries. In PostgreSQL and MySQL, table names are most often written in lowercase (or more precisely, snake_case). Have a clear code style in your projects so that it’s easier to read and navigate. Keep in mind: even though you can use different cases for your code, it doesn’t mean you should. By default, it’s case-insensitive, and like with MySQL, you can change this behavior by modifying the collation setting. However, you can change the behavior by changing collation. This means MySQL is case-insensitive in Windows and macOS, while it is case-sensitive in most Linux systems. By default, it depends on the operating system and its case sensitivity. This forces PostgreSQL to be case-sensitive for table names. However, you can easily modify this by adding double quotation marks (") to the table name. This behavior doesn’t depend on the operating system. In this database, table names are case-insensitive. For more information, refer to your DBMS documentation. We’ll focus on the three most popular relational databases, all of which are taught at : PostgreSQL, MySQL, and MS SQL Server. We won’t discuss the topic in detail, as there are many ways to customize the behavior. The user can also impact case sensitivity. In addition, the behavior depends on the operating system (i.e., Windows, macOS, or Linux). Unfortunately, different DBMSs work differently. This topic is a little bit more complicated. Are SQL Table and Column Names Case-Sensitive? If you’re still at the beginning of your programming journey, you may want to know how to learn the SQL syntax, as learning the syntax also includes learning keywords. You may have different courses with different projects, and switching between them is less time-consuming with a clear code style. Other option would be to upgrade the XAMPP version to the newest: 5.6 that comes with MariaDB instead of old MySQL.This also applies if you’re a student collaborating with other students. The hardware above described is a powerful server but, I am suspicious the free XAMPP stack is what is giving us most of the slow response times apart from the Internet connection speed. I would appreciate you guys could share what optimizations you have done or the specific server stack you use for production servers (the only thing is that the server has to be Windows not Linux… sorry, huh?). I could also try NGINX but will have to learn it first as well. The only other alternative I was thinking is replacing the XAMPP portion of the Web Server and PHP and use the Zend Server product from Zend company. The Internet connection can be improved but the thing is that even if we run the app locally in the server is not lightning fast. DB has proper indexes, it is not a gigantic DB. The server has 64GB RAM server and we have seen little improvements. I know that the speed of a Web Application depends on many factors but, I was wondering if the company (Scriptcase) recommends a specific server stack or if Zend Server can make our application run faster.ĭoes anybody know what is the platform or the stack that Scriptcase (the company) recommends for better performance results? We have deployed a web application developed in Scriptcase 8 (of course!) on a Windows 2008 Enterprise server (Intel Xeon E3-1240 3.50Ghz, 2TB SCSI HD) that uses the XAMPP stack (XAMPP 1.8.1, Apache 2.4.3, MySQLm 5.5,PHP 5.4.7).
