Top 5 SQL Features that you Should Know
Here in this section, we are going to discuss the 5 SQL Features you Need to Know. So, without wasting time let’s get started:
1. Dual Password
A lot of developers have appreciated the introduction of dual passwords in MySQL in the recent past. The concept of double password in SQL ensures that it supports current as well as a secondary password for the convenience of the user. Now, this should help the user for the transition to the new password in a straightforward way.
You do not have to live with the fear of changing the password at a frenetic pace. Once you have all the code update, you can remove your old password and start your work again. However, if you don’t want to deal with your new and old password, the best way is to ask SQL Server to generate a random password for you to counter lousy login.
2. Better Support than Before
If I am not wrong, then most of you have not observed powerful features in the previous versions of SQL. When SQL 8.0 came into the market, we have witnessed a lot of new features added to it.
Some of the features that are worth to be mention here are common table expression, windowing functioning, table operator support, lateral derived tables, and many more, which makes SQL be the robust query language for the users.
3. JSON Document Validation
It is tough to deal with data stored on a database, and previously relational database provides some ways in which the users get to know that the integers inserted into the integer’s columns to ensure data were within the specified range. But with JSON document validation in SQL 8.0, there is no option until recently to ensure that values were perfect of the exact data type in the right range.
4. Addition of the Data Dictionary
We must say that the addition of a data dictionary recently is the most significant change in the SQL versions. If you have ever been lost around with MySQL/ var/lib in the previous versions of this Structured Query Language and often wondered about those small files, then you might have come across your meta-data, for instance.
Now the exciting thing is the metadata is now stored within the database itself, which is known to be the data dictionary. You do not have to deal with in nodes; instead, you can be ensured of having millions of tables to choose from the dictionary.
5. The New My SQL Shell
The latest version of MySQL will see the new SQL shell known as MySQLsh. This is known to be the new CLI, which has a lot of horsepower in it. The new my SQL shell comes with three nodes; they are JavaScript, python, and Structured Query Language, and if you have libraries in JavaScript or python languages, you have the option to use it from the shell. You also have the opportunity to save script so that you can use it for future purposes.
Also, the option of the parallel bulk loader will allow the user to import CSV and JSON data very quickly that are there in the built-in utilities. If you want to check with the updates of my SQL, then you can do it with the upgrade checker.
Conclusion
These are the few changes that you can see in the MySQL latest version that is MySQL 8.0. If you want to know more features of SQL, then you can leave a comment in the comment box, and we will surely get back to you with a solution.
