MySQL Variables: How to Set Them

In MySQL, you can use the SET statement to set variable parameters. Here is a simple example:

SET @myVariable = 'Hello, World!';
SELECT @myVariable;

In this example, we are using the SET statement to assign a value of ‘Hello, World!’ to a variable named @myVariable. Then, we use the SELECT statement to view the value of the variable.

One option could be:
In addition to using the SET statement to assign values to variables, you can also directly assign values to variables in a query. For example:

SELECT @myVariable := 'Hello, World!';
SELECT @myVariable;

In this example, we assign ‘Hello, World!’ to the @myVariable variable using the SELECT statement, and immediately display the value of the variable.

Please note that variables in MySQL are preceded by the @ symbol to differentiate them from column names. You can use these variables in queries to store and retrieve data, as well as perform calculations and operations.
