How to use or operator with substr in oracle?

@jasen 

You can use the OR operator with SUBSTR in Oracle by including conditions for both substrings in the WHERE clause of your SQL query.

Here is an example syntax:

1
2
3
4

SELECT column_name
FROM table_name
WHERE SUBSTR(column_name, start_position, length) = 'substring1'
   OR SUBSTR(column_name, start_position, length) = 'substring2';

In this query, the OR operator is used to check if the SUBSTR function returns either 'substring1' or 'substring2' for the specified column_name. You can adjust the start_position and length parameters based on the position and length of the substring you want to check for.
