handsontable formula returning #NEED_UPDATE - javascript

I have a handsontable, for example:
+---+------+-------+-------+
| | A | B | C |
+---+------+-------+-------+
| 1 | 10 | 20 | 30 |
+---+------+-------+-------+
| 2 | 5 |=0.5+A3|=0.5+B3|
+---+------+-------+-------+
| 3 |=A1+A2|=B1+B2 |=C1+C2 |
+---+------+-------+-------+
when the table is loaded, B2 and C2 has value of #NEED_UPDATE instead of calculation result of its formula. how to handle this issue?

Nevermind, I solved this. add afterRender callback:
afterRender: function(){
this.setDataAtCell(ROW, COL, FORMULA);
}
this will automatically update all cell to the right.

Dexiejs - Filtering returns single value

My dexiedb structure looks like below.
const db = new Dexie('shipment-execution');
db.version(1).stores({
root: '++id,shipmentid,stopid',
})
My IndexedDB will look like below
| id| shipmentid| stopid|
| 1 | 6000001 | 10 |
| 2 | 6000001 | 20 |
| 3 | 6000001 | 30 |
| 4 | 6000002 | 10 |
| 5 | 6000002 | 20 |
I am trying to get all the data which has shipmentid equal to 6000001. Each time it is returning only one record (the first record ).
db.root.where({shipmentid : '6000001'}).toArray().then((d)=>{
console.log(d);
})
output is only fetching the first record
| id| shipmentid| stopid|
| 1| 6000001 | 10 |
Please let me know, what I am doing wrong.

posgresql: Selecting specific column in an existing table and sort it according to absolute values in descending order?

I have the following table:
+----------+----------+---------+----------+----------+----------+
| Date | A | B | C | P | D |
+----------+----------+---------+----------+----------+----------+
|2019-01-10| -111,000 | 666,000 | 78,000 | 45 | 120,000 |
|2019-01-09| 555,000 | 55,000 | 100,000 | 55 | 700,000 |
|2019-01-08| 48,000 | 30,000 | 40,000 | 65 | 450,000 |
|2019-01-07| 600,000 |-450,000 | -800,000 | 90 | 980,000 |
+----------+----------+---------+----------+----------+----------+
May I know how to create a temporary table from the existing table above to become the table as below:
+----------+----------+---------+----------+----------+
| Date |Components| Values | Comp_no | P |
+----------+----------+---------+----------+----------+
|2019-01-10| A |-111,000 | 1 | 45 |
|2019-01-10| B | 666,000 | 2 | 45 |
|2019-01-10| C | 78,000 | 3 | 45 |
+----------+----------+---------+----------+----------+
Then sort it according to absolute values as below:
Give numbers to the largest value as '1', 2nd largest as '2' and so on.
The sorted_comp_no represents the order whereby the components is sorted where '1' is 'B', '2' is A and '3' is C.
+----------+----------+---------+----------+----------+--------------+
| Date |Components| Values | comp_no | P | sort_sequence|
+----------+----------+---------+----------+----------+--------------+
|2019-01-10| A |-111,000 | 1 | 45 | 2 |
|2019-01-10| B | 666,000 | 2 | 45 | 1 |
|2019-01-10| C | 78,000 | 3 | 45 | 3 |
+----------+----------+---------+----------+----------+--------------+
Use the comp_no and sort.
The components are now sorted according to their values.
+----------+----------+---------+----------+----------+--------------+
| Date |Components| Values | comp_no | P |sorted_comp_no|
+----------+----------+---------+----------+----------+--------------+
|2019-01-10| B | 666,000 | 2 | 45 | 2 |
|2019-01-10| A |-111,000 | 1 | 45 | 1 |
|2019-01-10| C | 78,000 | 3 | 45 | 3 |
+----------+----------+---------+----------+----------+--------------+
I've already created the temporary table template but still stuck in taking the name of specific column only (A,B and C) to be put into a column of its own category ignoring column D . Column P is brought into the temporary table but remain as is. There is also a dependency to the date column as there are multiple data of different date.
But the end goal is to be able to "sort specific column according to its absolute value at a specific date dynamically".

How to parse data from a mysql tracking db?

I have a working event tracker that writes every event in a mysql table.
Table
id date userid event
5100 2014-03-25 14:18:55 user333 AI
5101 2014-03-25 14:19:02 user333 Click
5102 2014-03-25 14:19:02 user333 Click
...
Thats works so far very good. But now, I want to write a little report tool in node.js
I try to get the values with this SQL Query:
SELECT DATE_FORMAT(date,"%Y%m%d") AS date, event, count(*) AS count FROM databasetest WHERE date>="'+ daystartdate +'" AND date<="'+ dayenddate +'" GROUP BY YEAR(date), MONTH(date), DAY(date), event
Giving me this:
+----------+----------+-------+
| date | event | count |
+----------+----------+-------+
| 20140320 | AI | 6 |
| 20140320 | Click | 2 |
| 20140320 | swipe | 2 |
| 20140321 | Click | 6 |
| 20140321 | error | 5 |
| 20140321 | swipe | 2 |
| 20140321 | touch | 3 |
| 20140322 | AI | 3 |
| 20140322 | Click | 3 |
| 20140322 | error | 1 |
| 20140322 | mapsload | 3 |
| 20140322 | touch | 1 |
| 20140323 | AI | 2 |
| 20140323 | Click | 2 |
| 20140323 | touch | 5 |
| 20140324 | AI | 3 |
| 20140324 | Click | 1 |
| 20140325 | AI | 25 |
| 20140325 | Click | 48 |
| 20140325 | error | 16 |
| 20140325 | mapsload | 7 |
| 20140325 | swipe | 15 |
| 20140325 | touch | 32 |
+----------+----------+-------+
But I need the data in this form:
+----------+----------+-------+-----
| date | Click | AI | ....
+----------+----------+-------+-----
| 20140320 | 0 | 6 |
| 20140321 | 2 | 2 |
| 20140321 | 2 | 5 |
Is this possible with a SQL query or do I need to loop through the results in my javascript code. I tried many possible solution but didnt get it to work.
Thank you.
This is a very common question, keywords to search are "transpose" and "pivot". To save you the trouble, this is something that MySQL is not able to do. SQL Server (a MS product) can do this, though.
You will need to loop through the output and build the result set yourself.
var results = []
data.forEach(function(row, rowidx) {
results[row.date] = results[row.date] || {};
results[row.date][row.event] = results[row.date][row.event] || 0;
results[row.date][row.event] += row.count;
});

Ext JS 4 : GridPanel - Update a column cell values based on the updated cell

I have a grid panel showing article details. There are several columns. When our an employee change the one of cell value, I want to match all column field values based on the updated field.
+----------------------------------------+
| ROW ID | COL A | COL B | COL C | COL D |
+----------------------------------------+
| 1 | TR | IST | 100 | 12 |
+----------------------------------------+
| 2 | US | NY | 60 | 7 |
+----------------------------------------+
| 3 | DE | BER | 74 | 9 |
+----------------------------------------+
What I want to do, when user change the ROW-1 COL D value (12) with 15, the other rows COL D values should change automatically with 15.
+----------------------------------------+
| ROW ID | COL A | COL B | COL C | COL D |
+----------------------------------------+
| 1 | TR | IST | 100 | 15 | <- user has changed the value
+----------------------------------------+
| 2 | US | NY | 60 | 15 |
+----------------------------------------+
| 3 | DE | BER | 74 | 15 |
+----------------------------------------+
Updates your records in the edit event of the grid.
Here's an example:
Ext.widget('grid', {
renderTo: Ext.getBody()
,columns: [{dataIndex: 'a', header: 'Col A', editor: 'textfield'}]
,store: {
fields: ['a']
,data: [{a: 1},{a:2},{a:3}]
}
,plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1
})
]
,listeners: {
// this event is added to the grid by the CellEditing plugin
edit: function(editor, e) {
e.grid.getStore().each(function(record) {
record.set('a', e.value);
});
}
}
});
You should update the records in the store behind.
Something like
store.each(function(record){
record.set('col_d', 15);
});
