IN operator selects values that match any value in a given list of values ex. Select*from dept where location IN('delhi','mumbai');......and the IF EXISTS clause is used with DROP TABLE command,it checks whether the given table exists in the database or not & if it exists then it will be dropped from database ex. DROP TABLE IF EXISTS club;

advantage of using in-build methods over creating user defined methods

Posted by Oinam Kunjarani 7 years ago

CBSE > Class 12 > Informatics Practices

1 answers

Siddhant Singh Rathore 7 years ago

Typically, pre-defined functions are better, if they exist. They usually are optimized to operate in the least amount of time, no matter what the input (they optimize based on input type and size). Really, the only reason you should user-define something is if the functionality of the pre-defined code does not meet some certain requirement that you have. For example, there may be a search function that has been pre-defined and returns a boolean, but you need to know the index of the found item.
