I have been working a lot with JavaFX recently and it’s been a while since doing any SQL work.
After loading my project and running a few test commands I was pretty shocked to see that the SELECT statements were taking almost 15 seconds to produce a response!
Thankfully I quickly remembered I needed to reindex the table.
So as that I don’t forget again, best to make a note.
#INDEX THE TABLE CREATE INDEX idx_mytable ON mytable(field1, field2); #DROP THE INDEX ALTER TABLE mytable DROP INDEX idx_mytable;
Select query without index – Query completed in 15,333 ms
Select query with index – Query completed in 7 ms
Much better.
Indeed. Always worth to take a closer look at indexes when SQL queries are too slow 👍
