What is the method of assigning values to SQL variables?
In SQL, variables can be assigned values using the SET statement. The syntax is as follows:
SET @variable_name = value;
For example, to assign the value of 10 to a variable named @count, you can do the following:
SET @count = 10;
You can then use this variable in a SQL statement, for example:
SELECT * FROM table_name WHERE column_name = @count;
