How can Oracle extract the last two characters from a string?

To extract the last two characters of a string, you can use the SUBSTR function and the LENGTH function. Here is an example:

SELECT SUBSTR('YourString', LENGTH('YourString') - 1, 2) FROM dual;

In the code above, ‘YourString’ is the string you want to extract. The SUBSTR function is used to extract the last two characters of the string. The LENGTH function is used to get the length of the string, then subtract 1 to get the position of the second to last character.

You can replace ‘YourString’ in the code above with the specific string you want to extract, and then execute the SQL statement to get the result.
