I have data that I imported from a csv file. Each row reflects a person and his data. Two attributes are Sex and Pclass. I want to add a new column (predictions) that is fully depended on those two in one line. If both attributes' values are 1 it should assign 1 to th... | 2017/09/10 | [

] | You could try adding a composite index
```
create index test on screenshot (DateTaken, id)
``` | Try running this query:
```
SELECT COUNT(*) as total
FROM screenshot
WHERE DateTaken BETWEEN '2000-05-01' AND '2000-06-10';
```
The reference to `ID` in the `SELECT` could be affecting the use of the index. |

The `5730138` in `EXPLAIN` is an *estimate*. It can be larger or smaller than the actual value, sometimes by a large amount. Do not be bothered by it.
You have 2.8M of screenshots in that date range, correct? Well, it could take 15 seconds to scan the index to co... | Try running this query:

] | A Worksheet Change Event: Monitor Change in Column's Data
---------------------------------------------------------
* I personally would go with JvdV's suggestion in the comments.
* On each manual change of a cell, e.g. in column `A`, it will check the formula
`=SUM(A2:ALastRow)` in cell `A1` and if it is not correct ... | Use a nested function as below:
=SUM(OFFSET(A2,,,COUNTA(A2:A26))) |

* How to perform multiple I/O in a single thread?
* How to implement cooperative multitasking?

The control tower can be seen as the event loop and runway as the thread. Each plane is a separate function waiting to execute. In reality only one plane can land on the runway at a time.
