It helps you code fast with Code Completion and customizable Code Snippets by getting suggestions for keywords and stripping the repetition from coding. Example SQL statements were written in Navicat Premium. In today's blog we learned how the SQL CASE Statement can be employed to choose a value based on the underlying data. For example, we could use it to add a target audience column based on the film rating: The 2nd CASE syntax is ideal for testing discrete values against two or more conditions. Here is the complete CASE statement and query for MySQL: Since the statements are generic in nature, you may have to modify it slightly to suit your particular database type. You can use the Tab key to move from one to the next. In fact, you'll find the CASE statement at the top of the Flow Control list:Īfter you place the code snippet into the editor, editable sections are color coded to help identify them. Although you can create your own, Navicat comes with many standard SQL statements, including DDL and flow control statements. To help with the CASE statement, Navicat provides Code Snippets that you can simply drag & and drop into the SQL editor. We'll add a column that splits rental prices into three categories: "discount", "regular", and "premium".

It's a powerful database development and administration tool that can simultaneously connect to most popular databases, including MySQL, MariaDB, MongoDB, SQL Server, Oracle, PostgreSQL, and SQLite databases.

To try out the CASE statement, we'll be writing some queries against the Sakila Sample Database using Navicat Premium. If no comparison is true, the result after ELSE is returned, or NULL if there is no ELSE part: The second CASE syntax returns the result for the first value=compare_value comparison that is true. If no condition is true, the result after ELSE is returned, or NULL if there is no ELSE part: WITH provides a way to write auxiliary statements for use in a larger query. The CASE statement comes in two flavors: the first evaluates one or more conditions and returns the result for the first condition that is true. As we'll see in today's blog, it can be used to test for conditions as well as discrete values. So, once a condition is true, it will short circuit, thereby ignoring later clauses, and return the result. The CASE statement goes through conditions and returns a value when the first condition is met. CASE is a Control Flow statement that acts a lot like an IF-THEN-ELSE statement to choose a value based on the data.
