Answer 1

これを試して：

SELECT t1.id
  FROM tableName t1
 WHERE t1.kontrol = 0
   AND EXISTS (SELECT 1
                 FROM tableName t2
                WHERE t2.id = t1.id
                  AND t2.kontrol = 0
                  AND t2.timeS = t1.timeS + 1
                  AND EXISTS (SELECT 1
                                 FROM tableName t3
                                WHERE t3.id = t2.id
                                  AND t3.kontrol = 0
                                  AND t3.timeS = t2.timeS + 1
                                  AND EXISTS (SELECT 1
                                                FROM tableName t4
                                               WHERE t4.id = t3.id
                                                 AND t4.kontrol = 0
                                                 AND t4.timeS = t3.timeS + 1)))

Answer 2

SELECT DISTINCT t1.id
FROM table t1
     INNER JOIN 
     table t2 ON t2.TimeS+1 days=t1.TimeS
     INNER JOIN 
     table t3 ON t3.TimeS+2 days=t1.TimeS
     INNER JOIN 
     table t4 ON t4.TimeS+3 days=t1.TimeS
WHERE t1.Control = 0 AND
      t2.Control = 0 AND
      t3.Control = 0 AND
      t4.Control = 0

Answer 3

このクエリを試してください

select 
  id, 
  count(distinct TimeS) 
from 
  table1
where 
  kontrol=0
group by 
  id 
having 
  count(distinct TimeS) >= 4;
