Problem
If you are making the transition from MariaDB to SQL Server or vice versa it is helpful to have a comparison of similar commands between the two platforms. Sure you can do some searches to find the answer, but it would be helpful to have a list of common tasks and the equivalent SQL code for both database platforms.
Solution
The following tip will show a comparison of the T-SQL commands for SQL Server versus the SQL commands for MariaDB.
Requirements and setup
- SQL Server 2014, but 95% of the T-SQL commands will work on earlier versions as well
- The MariaDB should be installed. For this tip, I installed MariaDB and SQL Server on the same machine using the Windows OS. You can find the MariaDB installer here.
There are several ways to issue commands, but we will use the command line tools for both database systems.
How to start the command line in SQL Server
- SQL Server uses the sqlcmd as the command line to administer in SQL Server.
In order to start, in the cmd write sqlcmd.
How to start the command line in MariaDB
-
You can use the MySQL Client (MariaDB) to start the command line.
You will need to enter a password. This password was requested when installing the software.
