Alternatives to self join

I'm currently doing a self-join on a table 4 times on varying conditions.
Although it works fine, I'm not sure if there are any alternatives that
perform better. Please let me know.

Thanks!

Hi

Can you please send your original query and perhaps a small dataset sample?

Thanks
