sqliteHow do I use the SQLite SUBSTRING function?

The SQLite SUBSTRING function allows you to extract a substring from a string. The syntax for the SUBSTRING function is as follows: SUBSTRING(string, start, length).

For example, if you had a string 'Hello World' and wanted to extract the substring 'Hello', you could use the following code:

SELECT SUBSTRING('Hello World', 1, 5);

This would return the following output:

Hello

The code is composed of the following parts:

1. SELECT: This is an SQLite command that tells the database to return the result of the operation.
2. SUBSTRING(string, start, length): This is the SUBSTRING function, which takes three arguments:
   • string: The string from which you want to extract a substring.
   • start: The starting index of the substring, where the index of the first character is 1.
   • length: The length of the substring.

For more information on the SUBSTRING function, see this page.
