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 MySQL Connection You can connect to your MySQL server remotely however for. One good reason to use CONVERT is for removing the time portion from a datetime field. Enter a friendly name to best describe your connection in Connection Name text box. In SQL Server, you can change the data type of a value to another using the CONVERT function. Navicat is a good graphical tool for various databases. 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. Supported database systems: MariaDB, MySQL, MS SQL, PostgreSQL, SQLite, Interbase and Firebird Connect to servers via commandline Create and edit tables. 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. Configuring MySQL Server Properties Starting the MySQL Server Creating and Connecting to the Database Instance Creating Database Tables. 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. For example, if it’s required to allow access to the database called database for user user with password password and remote IP address 203.0.113.2: GRANT ALL ON database.* TO '203.0.113.Important SQL Server Functions - Miscellaneous Functions by Robert Gravelle Part 4: Miscellaneous Functions Grant access to remote IP address and login to MySQL. Note: For the access to client’s MySQL server on Windows, use PHPMyAdmin: Plesk > Tools & Settings > Database Servers – MySQL DB Admin. Start Plesk Services Monitor > select MySQLX or MariaDBX (where X is a version) > click Restart. If it is required to bind to specific IP address, specify this particular IP instead of 0.0.0.0Īlso, make sure that skip-networking parameter is not defined. Note: 0.0.0.0 means every IP address on the server. Location of this file is:Ĭhange bind-address parameter to: bind-address = 0.0.0.0 Apply Navicat Version No.: All Windows versions, Linux version 15 or above. Log in to Plesk and make sure the option Allow remote connections from any host is enabled at Tools & Settings > Database Servers > Settings.Ĭonnect to a Plesk server via SSH/ RDP and open the MySQL configuration file in any text editor.
