What is the purpose of the split method in SQL?

There is no built-in split method in SQL, but the functionality of split can be simulated using other methods.

The purpose of the split method is to divide a string into multiple substrings and return an array of strings. It is commonly used to handle strings containing delimiters, such as comma-separated or space-separated strings.

For example, the string “apple,banana,orange” can be split into three substrings “apple”, “banana”, and “orange” using the split method.

In SQL, you can simulate the functionality of split by using other functions or techniques, such as SUBSTRING, CHARINDEX, LEFT, RIGHT functions to extract different parts of a string, or using various string handling functions and regular expressions to achieve more complex splitting logic. The specific implementation method depends on the database system being used and the splitting logic that needs to be implemented.
