Feed: CronJ. Author: Priyanka Rai; With the introduction of ES6, which is the 5th version of scripting language specification standards specified by EcmaScript International, few of the very important concepts came.

There is a phrase in baseball about pitchers “pitching through pain” that refers to pitchers taking the mound to pitch even though they have aches and pains – sore arms, stiff joints, blisters, strained muscles, etc. The idea is that these pitchers are so tough that they can pitch effectively even though they are not quite physically right.  However, when the human system is asked to do something that it’s not prepared to do in the most effective manner, other bad habits emerge in an attempt to counter these ...

As per Wikipedia, Price Elasticity of Demand (PED or ED or PE) is a measure used in economics to show the responsiveness, or change, of the quantity demanded of a good or service to a change in its price when nothing but the price changes.

Chebychev’s Theorem gives bounds on how spread out a probability distribution can be from the mean, in terms of the standard deviation. More precisely, if (X) is a random variable with mean (mu) and standard deviation (sigma), then [P(|X – mu| ge k sigma) le frac {1}{k^2}.] When I was an undergraduate ... Read More

Now, I’m updating my student image with a more complete solution to show how to avoid update anomalies. In the prior post, I used a while loop in PHP, like the following: do { ... } while($stmt->next_result()); Using PHP Version 7.3.8 and MySQL 8.0.16, that now raises the following error message: Strict Standards: mysqli_stmt::next_result(): There is no next result set. Please, call mysqli_stmt_more_results()/mysqli_stmt::more_results() to check whether to call this function/method in /var/www/html/app/library.inc on line 81 ... Read More

Feed: Planet MySQL; Author: Michael McLaughlin; Somebody didn’t like the MySQLi Update Query example on the tutorialspoint.com website because it use the procedure mysqli_query style.

It relies on a MySQLCredentials.inc file that contains the hostname, user name, password, and database name. You can create create member table, like my example in MySQL 8, or any other table in your MySQL ... Read More
