The query (SELECT 15 > 14 FROM Duel) Working in MySql, but when I tried in MS-SQL Server getting following error:

SQL Error(102): Incorrect syntax near '>'

I have a requirement where I want to see if at least 1 record exist return 1 or else 0

SELECT count(emp.name) > 0
        FROM ****
        WHERE *** IN (***)

Check the db fiddle

Answer 1

You can use IIF to return a 1 or 0 based on a condition, see example:

SELECT IIF(COUNT(EmpID) > 0, 1, 0) AS [RecordsExist]
FROM Employee
WHERE EmpName IN ('Dave', 'Carol')

Returns 1 if any rows in the Employee table exist with an EmpName value of 'Dave' or 'Carol'

Answer 2

I have a requirement where I want to see if at least 1 record exist return 1 or else 0

You can do that with following query in MS-SQL (db-fiddle)

SELECT CASE WHEN count (*) >= 1 THEN 1 ELSE 0 END
FROM new_table_name

Not sure how mySQL treats this SELECT 15 > 14 FROM Duel, but in MS-SQL it's not complete statement (even columns exists with the name 15 and 14), operators (=, <>, !=, >, <, LIKE, IN, NOT IN) usually used in WHERE and ON clauses. When it used in SELECT clause it must complete the Boolean logic (CASE, IIF).
