I have written a Cursor, but the same issue is happening, columnid is not increasing by 1 each time through the loop. Any suggestions?

DECLARE @ColumnID INT
SET @ColumnID = (SELECT MAX([WorkCommentId]) FROM [abc].[WorkComment]) --CurrentID or Row Number
DECLARE @ID INT --Number of Rows to Process
DECLARE IDCursor CURSOR FOR
SELECT DISTINCT COUNT(WINFkey) from dbdb.dbo.winf w WHERE last_paid in    ('L17','L18','L19','L20','L21','L22','L23','L24','L25','L26','L27','L28','L29','L30','L31','L32'
                                                                            ,'L33','L34','L35','L35B','L36A','L36B','L36C','L37A')
OPEN IDCursor

FETCH NEXT FROM IDCursor INTO @ID

WHILE (@@FETCH_STATUS = 0)
    BEGIN
        --INSERT INTO [PPP].[WorkComment_test] ([WorkCommentId1],[WorkId],[Comments],[IsExternalViewable],[IsAlert],[CreatedBy],[CreatedDate],[UpdatedBy],[UpdatedDate],[IsDeleted],[RegistrationId])        
        SET @ColumnID = 1 + @ColumnID
  
        SELECT @ColumnID as 'ColumnId'
            ,SUBSTRING(w.WINFkey,3,LEN(w.WINFKEY))
    ,'Legacy Migration Information'
    ,1
    ,1
    ,'domain\testuser'
    ,GETDATE()
    ,SYSTEM_USER
    ,GETDATE()
    ,0
    ,0         
        FROM dbdb.dbo.winf w    
        WHERE last_paid in
        (
        'L17','L18','L19','L20','L21','L22','L23','L24','L25','L26','L27','L28','L29','L30','L31','L32','L33','L34','L35','L35B','L36A','L36B','L36C','L37A')        
    
    
    FETCH NEXT FROM IDCursor INTO @ID        
    
    END
CLOSE IDCursor
DEALLOCATE IDCursor
