Recursion vs for loop speed

Webb22 nov. 2016 · If there are few rows (let’s say 1000 rows), there is almost no performance difference between UNION and UNION ALL. However, if there are more rows, you can see the difference. The following example will create two tables with random values from 1 to 1,000,000 and then we will test UNION and UNION ALL with the tables created.

In this post, we’ll compare, discuss both methods and their complexities. Webb3 dec. 2024 · While looping is a group of code run over and over, recursion is a process always applied to a function. It is a problem-solving technique, where the function is applied to a new, broken down instance of itself. This is repeated until the base case is reached. In other words, the recursive function calls itself either directly or indirectly.
