Issue

SQLServer does not support dual table.

Solution

In SQLServer there is no dual table. If you want to use that then there is no need from keyword. We can use it as below

select 1

Note : In MySQL and Oracle need a FROM clause to use where clause while in SQL Server allow WHERE clause directly with out FROM clause.

For Example:
Oracle
SELECT 123 FROM DUAL WHERE 1<2
SQL Server
SELECT 123 WHERE 1<2
