Avoid using SQL COUNT(*) when you could use SQL EXISTS When checking for the existence of data, avoid using COUNT(*) > 0 as many implementations will nto be able to avoid the work of calculating the exact count

Checking if rows match some criteria?

SELECT COUNT(*) FROM ...

Use

EXISTS ( SELECT * FROM ...

COUNT gets all the rows; EXISTS can stop when it finds a match

As @lukaseder.bsky.social says

Thou shalt not use COUNT(*) when EXISTS sufficeth thy need
