[sql-server] How can I select from list of values in SQL Server

If it is a list of parameters from existing SQL table, for example ID list from existing Table1, then you can try this:

select distinct ID
      FROM Table1
      where 
      ID in (1, 1, 1, 2, 5, 1, 6)
ORDER BY ID;

Or, if you need List of parameters as a SQL Table constant(variable), try this:

WITH Id_list AS (
     select ID
      FROM Table1
      where 
      ID in (1, 1, 1, 2, 5, 1, 6)
)
SELECT distinct * FROM Id_list
ORDER BY ID;
