![]() In the following example, we will check whether the variable value is odd or even. In order to overcome this issue, we can use the CONTINUE statement. It’s also possible to access a list of previous queries if you need any. If you need to run a specific query several times, you can store it as a favorite. Assume that we want to write only even numbers in a WHILE loop. Download SQLPro for SQLite 2023.10 for Mac - A powerful and streamlined macOS utility designed to help developers easily and effortlessly navigate and manage SQLite databases. It will not work with other database servers such as MSSQL or PostgresSQL. This SQL Client is only for MySQL and MariaDB. ![]() The following flowchart explains the working logic of the BREAK statement example as visually:ĬONTINUE statement is used in the SQL WHILE loop in order to stop the current iteration of the loop when certain conditions occur, and then it starts a new iteration from the beginning of the loop. SQLPro for MySQL is a powerful MySQL & MariaDB database client which allows quick and simple access to MySQL Servers, including (but not limited to) those hosted in Amazon RDS and Microsoft Azure. If the condition of the IF…ELSE statement does not meet, the loop will run until the condition result will be false. For this reason, the message shows the values of the variable up to 7. In this example, we have checked the value of the variable, and when the value is equal or greater than 7, the code entered the IF…ELSE block and executed the BREAK statement, and so it exited the loop immediately. The syntax of the WHILE loop in SQL looks like as follows: If any SQL statement exists outside the loop, it will be executed. ![]() Otherwise, the code flow will exit the loop. If the result of the condition is true, the SQL statement will be executed. The following flowchart explains the essential structure of the WHILE loop in SQL:Īs you can see, in each iteration of the loop, the defined condition is checked, and then, according to the result of the condition, the code flow is determined. In the flowchart, each geometric symbol specifies different meanings. The flowchart is used to simply design and document the algorithms. The flowchart is a visual geometric symbol that helps to explain algorithms visually. For this reason, firstly, we will explain what is a flowchart briefly. In the following sections of this article, we will use more flowcharts in order to explain the notions and examples. SQL WHILE loop provides us with the advantage to execute the SQL statement(s) repeatedly until the specified condition result turn out to be false. ![]()
