In case of JOIN query with large tables, we have a lot of data in memory. This  can cause out of memory error.

One simple solution for handling this error is to change the RIGHT OUTER JOIN  to LEFT OUTER


JOIN. We should try to put the table with a large number of rows on the rightmost side in a JOIN query.
