SET SQL_MODE=MSSQL is an alias for the following sql_mode:
In MariaDB 10.4.5 and later, setting the sql_mode system variable to
MSSQL allows the server to understand a small subset of Microsoft SQL Server's language. For the moment
MSSQL mode only has limited functionality, but we plan to add more later according to demand.
Supported Syntax in MSSQL Mode
Using  for Quoting
One can use  instead of "" or `` for quoting identifiers:
SET SQL_MODE="MSSQL"; CREATE TABLE [t 1] ([a b] INT); SHOW CREATE TABLE [t 1]; Table Create Table t 1 CREATE TABLE "t 1" ( "a b" int(11) DEFAULT NULL )
You can use '[' in identifiers. If you want to use ']' in identifiers you have to specify it twice.
