Select from dual in T-SQL / SQL Server

visibility 106 comment 0 access_time 3 years ago

In Oracle database, you can select from dual table if you only want to return a one row result set. In many other databases, the query engine supports select directly from constant values without specifying a table name. 

In SQL Server, you can directly select values without specifying a table name. 

Code snippet

SELECT "Constant Value" AS COLUMN_NAME;
