![]() ![]() ![]() It is divided into three sections: the left panel displays all the available tables that exist in the current database, the upper graphical view allows you to view the selected tables and the lower panel displays all the SQL queries. ![]() It is similar to a spreadsheet, where each column represents a field and each row represents a record.īy using the ‘SQL Builder’ tab, which becomes available when you select the ‘New Query’ option, you are able to create and edit queries without learning the proper usage of commands. The ‘Object Designer’ option allows you to quickly create, modify and delete records using the grid view. Since it comes with an intuitive interface, you will find Navicat for SQL Server extremely easy-to-use no matter you are a database developer or a novice user. The toolbar allows you to access basic objects and features such as connections, users, backups, reports and models. The main window is very simple and displays all the available attributes, functions and foreign keys each time you open a table. Packs several useful tools into an intuitive UI After that, you are able to view all the available databases in the left panel, wherefrom a connection tree is created. Simply specify the host name and choose the authentication mode. When you launch the program for the first time, you can establish a secure SSH connection and enjoy a strong authentication and encrypted communication between two hosts. The application allows you to connect to various SQL Server databases and enables you import data from ODBC, create, edit and view tables, manage indexes, foreign keys and procedures and run SQL scripts. Powerful SQL Server database management solution Next time, we'll be moving on to numeric functions.Navicat for SQL Server is a straightforward and effective application whose main purpose is to provide its users with a graphical approach to database management and administration. In this first instalment of this series on Important SQL Server Functions, we looked at several useful string utility functions, including Len, Trim, Concat, Upper, and Lower. If there are more than one, each parameter is tabbable for quick access: Conclusion Once a function (or stored procedure) is selected, input parameters are highlighted for entry. As soon as you begin to type a word, a list of suggestions comes up that includes all database objects, including schema, table/view, column, procedure, and, of course, function names: One of the features of Navicat's SQL Editor is auto-completion. To show the effects of the Upper & Lower functions, we can show film titles in their original case and altered through each function: Working with Functions in Navicat These two counterpart functions take a string argument and return the same string but with all its characters cast to uppercase and lowercase, respectively. The following query combines the ID, title, and release year for each film and separates them using commas: Upper & Lower The concat function is really useful to format multiple columns together in a way that works for you and your users. Hence, the concat function combines two or more strings that we pass in as its arguments. In programming, the combining of strings is known as concatenation. We can use trim to find out if any of our film titles contain any leading or trailing spaces by comparing the length of the trimmed title to what's there currently: Concat Looking to trim some fat off of a string? Then the trim function is for you! It eliminates excess spaces and tabs from the beginning and end of a string that we pass in as its argument. The query selects the top 10 longest titles from the film table in descending order: Trim Here's the function signature:Īs an example, we'll execute a real query against the Sakila Sample Database using Navicat for SQL Server as our database client. In Microsoft products, there is a long tradition of calling this function "Len". One of the most useful string functions is one that returns its length in characters (including spaces and punctuation). Today's blog will tackle string functions, while subsequent installments will explore numerical, date functions, and more! Len In this series, we'll be taking a look at a few important SQL functions, as implemented by SQL Server. Each database vendor does not implement functions in exactly the same way, so it pays to familiarize yourself with functions that are specific to the database you work with. These may be applied to Char, Varchar, and Text data types. Although SQL differs from your typical procedural programming language like C# or Java in many ways, it too comes equipped with an impressive assortment of built-in functions. ![]() There are certain functions that seem to come up in every programming language.
