MariaDB Vs MySQL

In this article, we’ll look at some of the key differences between MySQL and MariaDB. Both are free and open-source databases, but MariaDB is faster, supports more storage engines, and has a more flexible license (GPLv2). Here, we’ll compare the advantages and disadvantages of each database to see which one is best for your needs. And if you’re a beginner, we’ll cover what to watch out for when comparing the two databases. MariaDB is faster than MySQL Both MySQL and MariaDB are database management systems. Both operate under the GPL, BSD, and LGPL licenses. They both support most standard querying

The Best Tools to Use MySQL

One of the most useful programs for MySQL developers is phpMyAdmin. With the help of this tool, you can create and administer MySQL databases. However, phpMyAdmin is not the only tool for MySQL developers. MySQL Workbench is another useful tool for database developers, database architects, and DBAs. Its features include data modeling, SQL development, and database administration. Both programs are available for Windows, macOS, and Linux distributions. Besides, they are designed to work best with multiple client connections. Beekeeper Studio If you need to create and maintain a database, you can find a wide range of useful tools in the

The Difference Between Float Vs. Double Data Types

It would be incorrect to say that floating-point numbers should never be used as an SQL data type for arithmetic. I will stick to double-precision floating-point data types for SQL Server that are suitable for my requirements. The double-precision floating-point data type is ideal for modeling weather systems or displaying trajectories but not for the type of calculations the average organization may use in the database. The biggest difference is in the accuracy when creating the database. You need to analyze the data types and fields to ensure no errors and insert the data values for maximum accuracy. If there

What Are The SQL Minus and Except Clauses

Structured Query Language (SQL) is the de-facto query language used in most database management systems (DBMS) such as Oracle and Microsoft SQL Server. This domain-specific language is used in programming to query and return the desired data from a database. We use SQL to write queries that declare what data to expect from a dataset without really indicating how to obtain it. We can also use SQL to update and delete information from a database. Ideally, in a relational database management system, the database usually runs on the “back end” side of a server in its structured form. By itself,

SQL Server Length Function Equivalent

The purpose of the Length function in SQL The SQL LENGTH function returns the number of characters in a string. The LENGTH function is available in many Database Management Systems (DBMS). The LENGTH Function Syntax LENGTH(string) LENGTH Function Notes If the input string is empty, the LENGTH returns 0. If the input string is NULL, the LENGTH returns NULL. Length Function Across Databases When working as a technical consultant, one has to work with customer’s databases and as you move from one database to another you will find that the function commands may vary–assuming the database has an equivalent function.

What is the difference between left join and left outer join in SQL

If you’re confused between a LEFT JOIN and a LEFT outer JOIN in SQL, you’re not alone. There are plenty of examples that explain both. In this article, we’ll explore LEFT JOIN, which combines the records from table1 with any matched records in table2, and OUTER JOIN, which combines records from both tables. RIGHT joins a set of records from table1 The RIGHT JOIN clause selects rows from table2 that match the criteria in the left-hand column. The RIGHT JOIN does not include NULL values in the left-hand column. Hence, the results from this query are the same as those
