Hi

I really like to do efficient SQL queries so, my question is if I am
expecting no more than one row from a select, using  the LIMIT 1 could
improve the performance?

 

If I use my logic, the LIMIT 1 instruction tell to postgres that stop
searching when found 1 record, but maybe it is unnecessary

 

 

Thanks

 

Anibal
