HAVING points > 10 I don't have experience with MariaDB, but in MySQL, something like that will work as long as I do `SELECT sum(points) AS total FROM ... HAVING total > 10`.

I've spent a *lot* longer to shave off a *lot* less. https://www.conductor.com/academy/page-speed-resources/faq/amazon-page-speed-study/ Re: Improve HAVING BY performance Programming Databases by Dani Now as far as whether going down that rabbit hole that day was worth the cost of losing AndreRet, then I'd have to give a resounding no. Re: Improve HAVING BY performance Programming Databases by Reverend Jim I have to admit that 95% of my work from 1995 to 2008 was back end stuff where I didn't have to worry about stuff like that. Digital plumbing and monitoring. The other 5% was single user apps. Not counting the 20% which was pointless meetings. So if you don't mind explaining, I'm curious as to why 50ms would even be noticible. I'm not asking just … Re: Improve HAVING BY performance Programming Databases by Dani I'm too exhausted for an in depth explanation right now but 90% of web development is optimizing for performance. The average DaniWeb page takes anywhere from 80ms up to 250ms to load the HTML (when dealing with low network latency), depending on the type of page, so shaving 50ms off of that is a huge win.

Kind of, MariaDB is a fork of MySQL from around 2009 or something like that, MySQL 5.* and the creator continued developing MariaDB and Oracle took … Re: Improve HAVING BY performance Programming Databases by Dani > Point #2 would apply if the improvement was noticible but I doubt anyone could seriously comment, "I think this page rendered 50ms faster than it used to", especially considering all the other things that affect timing, for example, the current loading on my ISP servers, anything else running on my computer or home network, etc. … Re: Improve HAVING BY performance Programming Databases by Dani > I know that in my experience, OR's are very bad for speed you can get away with a few but they can get very bad when they stop the whole query making use of one of the main indexes, you can actually speed it up by moving the or's into the HAVING usually. Thank you for that tip! I never thought of that, but it totally makes sense!! > … Re: Improve HAVING BY performance Programming Databases by toneewa I'm a little late to the party, however, I want to share my experience learning MySQL in the past day. I setup a server, a database, and wrote a C++ program to connect to it. It measures the times for 3 SELECTs. The whole product list, using HAVING, and WHERE. I also tested reversing the orders. Query execution time: 0.0002336 seconds … Re: Improve HAVING BY performance Programming Databases by Dani But you're not comparing apples to apples. Your WHERE query and your HAVING query perform different calculations and do different things. In one, you're plucking out all the rows with a price greater than $4, and then calculating an average price for each product. In the other, you're plucking out *all* rows, calculating an average price for each … Re: Improve HAVING BY performance Programming Databases by toneewa Correct. It wasn't about displaying the results, but to measure the different clauses. I'm not impressed by only 95 INSERTs/sec, and a maximum write speed of 175 KB/s for importing data. Increasing to 50K shows WHERE to be faster. 50K: WHERE Query execution time: 0.0599129 seconds HAVING Query execution time: 0.0621748 … Re: Improve HAVING BY performance Programming Databases by Dani I think you might be missing my point. If you’re fetching different data, there’s no way of saying whether where or having is faster. You would need to write queries that use each, but retrieve the same data, to see which is faster for a use case. Even then, it totally depends on the data in the database itself. The same query can be fast for some … Re: Improve HAVING BY performance Programming Databases by toneewa I know when you don't use aggregate calculations use WHERE. Producing the same results can be done. I added another test with MAX(Price). With a database over 305K rows, 3 columns, MySQL Workbench is unstable importing. Took over 2 hours. WHERE is faster, and should be used, when no functions are needed. WHERE Query execution time: 0.… Re: Improve HAVING BY performance Programming Databases by Biiim > INSERT INTO electronics.products(ProductID, ProductName, Price) VALUES ('1','capacitors', 2.50), ('2','resistors', 4.50), ('3','rectifiers', 7.50), ('4','diodes', 10.00), ('5','ICs', 25.00), ...

Took 4.375 secs in MySQL Workbench. It did speed up the results. I'll have to try another method of importing to see if I can improve this. I also ommitted the overhead of converting variables for display output measurements, because they were included in the C++ times.
