The IF statement for stored programs implements a basic conditional construct. There is also an IF function , which differs from the IF statement described here. See Section An IF END IF block, like all other flow-control blocks used within stored programs, must be terminated with a semicolon, as shown in this example:. As with other flow-control constructs, IF You can use indentation to make nested flow-control blocks more easily readable by humans although this is not required by MySQL , as shown here:.

Based on a certain condition, it allows us to execute a set of SQL statements. Let us see each of these statements in detail. This statement executes a set of SQL queries based on certain conditions or expressions. In the above syntax, we have to specify a condition for executing the code. The IF ENDIF block executes with stored programs and terminates with a semicolon, as shown in the below example. If we want to execute other statements when the condition specifies in the IF block does not evaluate to true, this statement can be used. Let us modify the above myResult stored procedure. So, first, remove myResult stored procedure by using the command below:. If we want to execute a statement based on multiple conditions, this statement can be used. Otherwise, it will evaluate elseif-condition. When the elseif-condition becomes true, it will execute the elseif-statement.

Decision Making in scripting is similar to decision-making in real life. In scripting, DBAs face some situations where they want a certain part of the script to be executed when some condition is fulfilled. Skip to content. Change Language. Open In App. Related Articles.

Structured Query Language SQL forms the backbone of many modern data-driven applications, offering a rich set of commands to manipulate and query relational databases. We will uncover the syntax and explore how to implement various logical scenarios with a series of code examples to guide us through the learning process. This will not only enhance our understanding of conditional logic in SQL but also equip us with practical skills to optimize database queries and procedures. This structure lays the foundation for more complex decision-making processes within stored procedures and functions in MySQL. It enables SQL programmers to guide the flow of execution based on varying conditions that can be evaluated within the database queries. Here are some best practices to keep in mind:. Through careful implementation and adherence to best practices, one can construct sophisticated queries and procedures that address complex data operations with precision and reliability.
