Hey @superichmann, thanks for submitting the issue.

Could you specify the following:

• The query in question
• What is the value of count property in /exec XHR API response for this query?
• What is your system? (also locale - language)

reproduce:

1. Download&Install QDB 7.2 for windows
2. Download this dataset
3. import into qdb, default settings
4. run this

CREATE TABLE 'train' (
  id DOUBLE,
  date TIMESTAMP,
  store_nbr DOUBLE,
  family SYMBOL,
  sales DOUBLE,
  onpromotion DOUBLE
) timestamp(date);

6. run this
   INSERT INTO train SELECT * FROM train.csv
7. run this
   SELECT * FROM (train d LT JOIN (train c LT JOIN (train b LT JOIN (train a WHERE a.date<'2017-08-01' and a.date>'2017-06-15' AND a.family='HOME AND KITCHEN I') ON family WHERE b.date<'2017-08-01' and b.date>'2017-06-15' AND b.family='HOME AND KITCHEN I') ON family WHERE c.date<'2017-08-01' and c.date>'2017-06-15' AND c.family='HOME AND KITCHEN I') ON family WHERE d.date<'2017-08-01' and d.date>'2017-06-15' AND d.family='HOME AND KITCHEN I') LIMIT 3,99999999999999999
8. observe selected rows amount
