Problem 1

How can I get lowest value from table (not null), for ID_CAR? For example, for ID_CAR 1 lowest value is 50, for ID_CAR 2 lowest value is 50 and for ID_CAR 3 lowest value is 300. I don't need duplicates, I need only one value for one car.

ID_CAR | col_1 | col_2 | col_3 | col_4 | col_5 | col_6 

1      | null  | 250   | 300   | null  | 900   | null
2      | 100   | null  | 300   | 600   | 200   | 100
1      | 300   | 100   | 800   | 100   | 50    | 900
3      | 300   | 4000  | null  | null  | null  | null
2      | null  | null  | null  | 50    | null  | 100
4      | 400   | 900   | 500   | 700   | 800   | 500

Problem 2 In this example, values in col_* are days. I need to add days to col_date and get lowest. For example lowest date for ID_CAR 1 is 2018-01-03 (col_2) and for ID_CAR 2 is 2018-01-15 (col_4).

ID_CAR | col_1 | col_2 | col_3 | col_4 | col_5 | col_6 | col_date

1      | null  | 2     | 3     | null  | 5     | null  | 2018-01-01
2      | 1     | null  | 3     | 6     | 10    | 10    | 2018-01-13
1      | 3     | 20    | 80    | 10    | 50    | 90    | 2018-01-02
3      | 30    | 40    | null  | null  | null  | null  | 2018-01-03
2      | null  | null  | null  | 5     | null  | 10    | 2018-01-10
4      | 10    | 9     | 5     | 70    | 8     | 50    | 2018-01-07

Getting Minimum and Maximum Values, How do you find the minimum value of a table? How can I get lowest value from table (not null), for ID_CAR? For example, for ID_CAR 1 lowest value is 50, for ID_CAR 2 lowest value is 50 and for ID_CAR 3 lowest value is 300. I don't need duplicates, I need only one value for one car.


You need UNION :

select id_car, min(val) as lowest_value
from (select id_car, col_1 as Val
      from table union 
      select id_car, col_2
      from table
      . . .
     ) t 
group by id_car;

How to VLOOKUP the lowest value and return adjacent cell in Excel?, To get the maximum value of a numeric column use the MAX() function. SELECT MAX(<numeric column>) FROM <table>; SELECT MAX(<numeric column>) FROM <table> GROUP BY <other column>; To get the minimum value of a numeric column use the MIN() function. To find the n lowest values in a set of data, you can use the SMALL function. This can be combined with INDEX as shown below to retrieve associated values. In the example shown, the formula in F7 is: Note: this worksheet has two named ranges: bid (C5:C12), and company (B5:B12), used for convenience and readability.


The following query will give you the required result

select tab.ID_CAR, min(tab.val) as lowest_value from
(
      (select ID_CAR,min(col_1) val
      from table
      group by ID_CAR)
  union
      (select ID_CAR,min(col_2) val
      from table
      group by ID_CAR)
  union
      (select ID_CAR,min(col_3) val
      from table
      group by ID_CAR)
  union
      (select ID_CAR,min(col_4) val
      from table
      group by ID_CAR)
  union
      (select ID_CAR,min(col_5) val
      from table
      group by ID_CAR)
  union
      (select ID_CAR,min(col_6) val
      from table
      group by ID_CAR)
) tab
group by tab.ID_CAR

Excel formula: Lookup lowest value, This example shows how to use INDEX and MATCH to get information from a table based on an exact match. In the example shown, the formula in cell H6 is: =​  The MIN function ignores the NULL values. The following is the syntax of the MIN function: The ALL modifier instructs the MIN function to find the minimum value in all values including duplicates. The MIN() function uses the ALL modifier by default so you don’t have to specify it explicitly.


Try this If you are expecting values greater than 9999999999999999999, then use a higher values

select id_car,
min(least(coalesce(col_1,9999999999999999999),coalesce(col_2,9999999999999999999),coalesce(col_3,9999999999999999999),
          coalesce(col_4,9999999999999999999),coalesce(col_5,9999999999999999999),coalesce(col_6,9999999999999999999)
        )
    ) as min_val 
from your_table
group by id_car

To calculate gas (​MPG) based on odometer readings you can build a table with a few simple  This is just a preview. You need to be signed in with a Basic account to view the entire video. Finding the minimum and maximum values for particular column can help you get an insight in to what's happening in your data. To get the maximum value of a numeric column use the MAX () function.

The naive approach would be using least:

SELECT ID_CAR, least(t.col_1, t.col_2, t.col_3, t.col_4, t.col_5, t.col_6)
FROM
(SELECT ID_CAR, min(col_1) as col_1, min(col_2) as col_2, min(col_3) as col_3, min(col_4) as col_4, min(col_5) as col_5, min(col_6) as col_6
FROM YOUR_TABLE GROUP BY ID_CAR) t;

However: If ANY argument to LEAST is NULL, it'll return NULL. You'll either need to convert the NULLs to a high value (which is a hack but will work in practice, see other answers for this).

Which means doing something like this:

SELECT ID_CAR, LEAST(col_1, col_2, col_3,
                     col_4, col_5, col_6) as l
FROM
(SELECT ID_CAR, 
   IFNULL(min(col_1), 9999)  as col_1, 
   IFNULL(min(col_2), 9999)  as col_2,
   IFNULL(min(col_3), 9999)  as col_3,
   IFNULL(min(col_4), 9999)  as col_4,
   IFNULL(min(col_5), 9999)  as col_5,
   IFNULL(min(col_6), 9999)  as col_6
FROM YOUR_TABLE GROUP BY ID_CAR) t;

However, it might be good to use a trick to convert your table into a three row table of the form:

car_id | attr | value
     1      1    NULL   ; or use strings such as "size"
     1      2     250
