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 Difference Between Float Vs. Double Data Types

Posted on by

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,

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

Posted on by

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
