I hope the above tutorial helped you to know about the CASE Statement in MYSQL. So you need to be careful when choosing the order that you give your conditions in. Once a condition goes true, the CASE statement will return the value as a result and not make use of those conditions further. You need to just keep in mind that the conditions are processed based on the order that is listed by yourself. One important aspect when writing CASE Statements in MySQL is that its ordering in the right way. Based on the details, the user can navigate through this link: ‘’ or ‘.’ Sample Query: SELECT Let’s check this out with an example.Ĭonsider a table named MEMBERS, which holds memberID and websiteID. Apart from this, you can also make use of the CASE statement for comparing any conditions. Depending on this, you can sort the tuples in the Employee table. The above function takes the arguments as the varchar data type variable. The output of the above sample query will get sorted based on the given fields. The output of the above query will be Employee ID Now we are going to write a query that is going to change F to Female and M to Male.Ĭlick Here – Get Prepared for SQL Interviews Sample Query SELECT Employee ID, Name, AOE, We can see every value in the Gender field has a single character, i.e., M/F. Let’s consider another example you have to choose every field based on the Employee table. The Area of Expertise names will be replaced as follows. If the area of expertise is SW, it should be converted to Software, NW to Network, Mech to Mechanical, and IT to Information Technology. We are going to modify the area of expertise names to their full forms. I’m creating a table: Employee Employee Table Employee ID Let me explain the above syntax with a practical example. I am not considering a sch_condition replacing the variable equality and implementing the state_list based on it. I am taking a variable called num_value, and I’m matching it with a state_list. There are two important ways to achieve CASE-switch statements. Let’s check out the syntax of the CASE Statement.Ĭlick Here – Get SQL Training with Real-Time Projects CASE In case there is no ELSE clause, and no conditions are true, then the CASE Statements returns NULL. In case no requirements are true, then it makes use of the ELSE clause to return the value. Once the condition becomes true, the CASE statement will stop the process of traversing and deliver the result. The CASE statement in MySQL makes use of the different conditions and then return values when the first requirement is met. It’s one of the control statements that acts as the cell of programming languages because they are capable of managing the other set of statements and their executions. What do you mean by the CASE Statement in MySQL?ĬASE statement in MySQL is considered as the best way to handle the if or else logic. We have learned the basics of SQL, not let’s discuss the CASE Statement in MYSQL. The developers make use of the SQL statements to perform different tasks like insert, update, retrieve, or data from the database. The American National Standards Institute states that SQL is termed as the standard language for the RDBMS. SQL is extensively used for communicating the data with the database. It’s developed for controlling the data stored in an RDBMS(Relational Database Management Systems) or for the relational data stream management system stream processing. SQL is termed as the domain-specific language used in programming extensively. In this tutorial, we will learn about the CASE statement in MySQL in depth. There is plenty of data getting generated every day, and therefore it’s significant to retrieve data depending on some conditions.
