I have a table like this:

   name col2       cnt
    B5  2.00000000  62
    B6  2.00000000  9
    B4  3.00000000  1
    B5  3.00000000  75
    B6  3.00000000  62
    B5  4.00000000  9
    B6  4.00000000  11
    B5  5.00000000  102
    B6  5.00000000  37

I want output as : B4 i.e., all the names where 2.00000000 never occurred in col2. How do I do that? I'm using SQL Server.

You can use EXISTS and a correlated subquery to check if a value of 2.00000000 exists for a name.

SELECT DISTINCT
       t1.name
       FROM elbat t1
       WHERE NOT EXISTS (SELECT *
                                FROM elbat t2
                                WHERE t2.name = t1.name
                                      AND t2.col2 = 2.00000000);

(I assumed 2.00000000 is numeric. If it's a string, put single quotes around it.)

Alternatively you can use conditional aggregation to count the occurrences of 2.00000000. Use a HAVING to only keep the rows where this count is 0.

SELECT t1.name
       FROM elbat t1
       GROUP BY t1.name
       HAVING count(CASE
                      WHEN t.col1 = 2.00000000 THEN
                        1
                    END) = 0
