This article mainly introduces "how to optimize MySQL sentences". In daily operation, I believe many people have doubts about how to optimize MySQL statements. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "how to optimize MySQL sentences". Next, please follow the editor to study!
If you want to do good work, you must first sharpen its tools. The first thing we need to do is to find a useful interface tool. I don't think you want to be with such a dark interface all the time:
If there is no gorgeous interface for us, how can MySQL be so famous in the industry? The first is, of course, MySQL's own UI artifact MySQL Workbench.
This tool has a very high degree of specialization, day-to-day development, even database management, backup, data import and export functions are integrated. I have one in hand and I have it in the world!
Pure one-stop operation, the largest and whiteest area in the middle, is for you to write SQL. The browser on the left cleverly divides database objects and database management functions into two Tab. Even shutting down the database came in.
There are all kinds of magical powers in the menu. It's all right to come in and have a look. You can find a lot of interesting stories. Anyway, it's not the company's database. I can play with my own database.
We often say that the database memory burst, in fact, we are looking at InnoDB Buffer Usage. For the time being, we'll leave him alone. After all, we didn't come here for DBA at first.
With such an economical and practical workbench, why are there endless MySQL visualization tools? In fact, for this part of the heresy of programmers, if we find imperfect tools, we will create our own. Apart from being single-minded to our wives, we are picky about tools.
Ten thousand green among a little red, the deepest favorite of MySQL programmers is Navicat.
If I have the money to buy Dell or even Mac, I'd rather use it to buy Navicat. Because it really works!
Look at the following code:
SELECT sno,AVG (grade) FROMsc xWHERE (SELECT AVG (grade) FROMsc yWHERE y.sno=x.sno) > = 80
Does it look like something at first glance?
Put it in Navicat, click beautify SQL (), our Loli "under the temple of Qiobiluo" is back, have you?
There's a feeling of heartbeat right away, isn't it?
Of course, we SQL programmers are not just face control, the inherent quality of the tools is enough to capture our hearts, oh no, the determination to buy.
As a developer and designer of a data warehouse, it is common to deal with two or more databases at the same time. You want us to open Toad, MySQL Workbench, SSMS, connect Oracle, MySQL, SQL Server respectively, and then we may also open RebooMongo to check MongoDB Audit. Oh, my God, with so many tools, the memory is not 32 gigabytes like me, it exploded a long time ago. Then comes the advantage of Navicat, as long as one interface, connect to all SQL databases! The best editor is the one that saves us programmers time.
At this point, the study of "how to optimize MySQL sentences" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
