How to group similar names using PHP from mySQL results? - javascript
I am running this query
SELECT distinct make, model FROM `used`order by make
in order to get all the available make / models in the database.
My end goal though is to edit the date using PHP and have this result:
var alfa-romeo= '<select name="stage_type">
<option value="Mito">Mito</option>
</select>';
var audi= '<select name="stage_type">
<option value="A4">A4</option>
<option value="A5">A5</option>
<option value="Allroad">Allroad</option>
</select>';
for all the results.
How can I do this?
Consider the following...
<?php
/*
DROP TABLE IF EXISTS cars;
CREATE TABLE cars
(car_id SERIAL PRIMARY KEY
,make VARCHAR(20) NOT NULL
,model VARCHAR(20) NOT NULL
,UNIQUE(make,model)
);
INSERT INTO cars (make,model) VALUES
('Alfa Romeo','Mito'),
('Audi','A4'),
('Audi','A5'),
('Audi','Allroad'),

('Citroen','C-ELYSEE'),
('Citroen','C1'),
('Citroen','C3'),
('Citroen','C4'),
('Citroen','C4 Grand Picasso'),
('Citroen','C4 Picasso');
SELECT * FROM cars ORDER BY make,model;

How to combine multiple queries from sqlite3 table from node.js
I just started with sqlite3 and was stuck on using (union) and combining multiple queries, is there a proper way of doing this I am dealing with the following data sql table => account |ledger_num | date_from | interest | name | loan | loan_type ____________|___________|_______________|_______________|___________|_________|____________________ Book_1 | HP2269 | 2017-03-31 | 15 | Samuel | 120 | type_a Book_3 | HP2236 | 2020-03-31 | -20 | bob | 190 | type_a Book_1 | HP2269 | 2019-04-01 | 250 | Samuel | 1500 | type_b Book_3 | HP2236 | 2019-04-01 | -3 | bob | 36 | type_b Book_2 | L01 | 2020-03-31 | 16 | josh | 95 | type_a Book_1 | HP2269 | 2022-04-01 | 400 | Samuel | 4050 | type_c and this is what I am trying to do var sql_1 = `SELECT SUM(loan) ,SUM(interest) FROM allYearAllAcc WHERE (account = 'Book_1' AND date_from > '2018-03-31')` var sql_2 = `SELECT SUM(interest) FROM allYearAllAcc WHERE (account = 'Book_2' AND date_from > '2017-04-01' AND interest < 0)` var sql_3 = `SELECT SUM(loan) FROM allYearAllAcc WHERE (account = 'Book_3' AND date_from < '2022-04-01')` temp_db.all(``+sql_1+`UNION`+sql_2+`UNION`+sql_3+``,(err,data)=>{ console.log(data) }) this clearly isn't working I want this to appear as an json array which I have to use it in my code
Use conditional aggregation with a single query on your table: SELECT SUM(CASE WHEN account = 'Book_1' AND date_from > '2018-03-31' THEN loan ELSE 0 END) AS loan1, SUM(CASE WHEN account = 'Book_1' AND date_from > '2018-03-31' THEN interest ELSE 0 END) AS interest1, SUM(CASE WHEN account = 'Book_2' AND date_from > '2017-04-01' AND interest < 0 THEN interest ELSE 0 END) AS interest2, SUM(CASE WHEN account = 'Book_3' AND date_from < '2022-04-01' THEN loan ELSE 0 END) AS loan2 FROM allYearAllAcc;
how to concatenate bits in javascript?
I want to concatenate the bits of two number values like this: +---------+---------+---------+-----------------+ | | val1 | val2 | concatenate val | +---------+---------+---------+-----------------+ | decimal | 18 | 16 | 592 | | hexa | 0x12 | 0x10 | 0x250 | | binary | 0b10010 | 0b10000 | 0b1001010000 | +---------+---------+---------+-----------------+ I have try to just concatenate with + like that : const test = 0b10010, test1 = 0b10000 console.log(test+test1)//return 34 It does not concatenate the values but adds them together.
You could shift the first value by the bitwise length of the second value before adding. const add = (a, b) => (a << Math.ceil(Math.log2(b)) + 1) + b; test = 0b10010, test1 = 0b10000, console.log(add(test, test1)); //
Permutation tree not making sense with the code
I watched a youtube video where this basic permutation tree was shown. If you look at this bit of code: function recursion(input, set = [], result = []) { if (!input.length) { result.push([...set].join('')); } for (let i = 0; i < input.length; i++) { const newArr = input.filter((n, index) => index !== i); set.push(input[i]); recursion(newArr, set, result); set.pop(); } return result.join(', '); } you can see that the base case (if statement) is at the top before the parameter nums is filtered. So, my whole question is how the tree and the code makes sense because for me the code would remove one too many digits from the set array. Becuase it pops an item of when returning and doesn't it return more than two times?
Does this log add clarity? / entering recursion with input = [1,2,3], set = [], result = [] | looping, i = 0 | adding 1 to set | / entering recursion with input = [2,3], set = [1], result = [] | | looping, i = 0 | | adding 2 to set | | / entering recursion with input = [3], set = [1,2], result = [] | | | looping, i = 0 | | | adding 3 to set | | | / entering recursion with input = [], set = [1,2,3], result = [] | | | | adding 123 to result | | | \ returning [123] | | | removing 3 from set | | \ returning [123] | | removing 2 from set | | looping, i = 1 | | adding 3 to set | | / entering recursion with input = [2], set = [1,3], result = [123] | | | looping, i = 0 | | | adding 2 to set | | | / entering recursion with input = [], set = [1,3,2], result = [123] | | | | adding 132 to result | | | \ returning [123,132] | | | removing 2 from set | | \ returning [123,132] | | removing 3 from set | \ returning [123,132] | removing 1 from set | looping, i = 1 | adding 2 to set | / entering recursion with input = [1,3], set = [2], result = [123,132] | | looping, i = 0 | | adding 1 to set | | / entering recursion with input = [3], set = [2,1], result = [123,132] | | | looping, i = 0 | | | adding 3 to set | | | / entering recursion with input = [], set = [2,1,3], result = [123,132] | | | | adding 213 to result | | | \ returning [123,132,213] | | | removing 3 from set | | \ returning [123,132,213] | | removing 1 from set | | looping, i = 1 | | adding 3 to set | | / entering recursion with input = [1], set = [2,3], result = [123,132,213] | | | looping, i = 0 | | | adding 1 to set | | | / entering recursion with input = [], set = [2,3,1], result = [123,132,213] | | | | adding 231 to result | | | \ returning [123,132,213,231] | | | removing 1 from set | | \ returning [123,132,213,231] | | removing 3 from set | \ returning [123,132,213,231] | removing 2 from set | looping, i = 2 | adding 3 to set | / entering recursion with input = [1,2], set = [3], result = [123,132,213,231] | | looping, i = 0 | | adding 1 to set | | / entering recursion with input = [2], set = [3,1], result = [123,132,213,231] | | | looping, i = 0 | | | adding 2 to set | | | / entering recursion with input = [], set = [3,1,2], result = [123,132,213,231] | | | | adding 312 to result | | | \ returning [123,132,213,231,312] | | | removing 2 from set | | \ returning [123,132,213,231,312] | | removing 1 from set | | looping, i = 1 | | adding 2 to set | | / entering recursion with input = [1], set = [3,2], result = [123,132,213,231,312] | | | looping, i = 0 | | | adding 1 to set | | | / entering recursion with input = [], set = [3,2,1], result = [123,132,213,231,312] | | | | adding 321 to result | | | \ returning [123,132,213,231,312,321] | | | removing 1 from set | | \ returning [123,132,213,231,312,321] | | removing 2 from set | \ returning [123,132,213,231,312,321] | removing 3 from set \ returning [123,132,213,231,312,321] You can see how I added the logging to your code in this snippet: const log = (depth, message) => console .log ('| '.repeat (depth) + message) function recursion(input, set = [], result = [], depth = 0) { log (depth, `/ entering recursion with input = [${input}], set = [${set}], result = [${result}]`) if (!input.length) { log (depth, `| adding ${[...set].join('')} to result`) result.push([...set].join('')); } for (let i = 0; i < input.length; i++) { log (depth, `| looping, i = ${i}`) const newArr = input.filter((n, index) => index !== i); log (depth, `| adding ${input[i]} to set` ) set.push(input[i]); recursion(newArr, set, result, depth + 1); log (depth, `| removing ${input[i]} from set` ) set.pop(); } log (depth, `\\ returning [${result}]`) return result.join(', '); } console .log (recursion([1, 2, 3])) .as-console-wrapper {min-height: 100% !important; top: 0} (but the console output there is limited to the last 50 lines.)
Math in JavaScript (Numbers)
I have a table as follows: +----+----+----+ | A | B | C | +----+----+----+ | 1 | 2 | 3 | +----+----+----+ | 4 | 5 | 6 | +----+----+----+ | 7 | 8 | 9 | +----+----+----+ | 10 | 11 | 12 | +----+----+----+ | 13 | 14 | 15 | +----+----+----+ | 16 | 17 | 18 | +----+----+----+ | 19 .... If I choose a random number (for example : 24) The number 24 will be in C Is there a way to know where any number will be located?
If it's just converting number to character based on this logic, you can use String.fromCharcode() like this: const getChar = n => String.fromCharCode((n-1) % 3 + 65) console.log(getChar(1)) console.log(getChar(2)) console.log(getChar(3)) console.log(getChar(4))
I think like this code function get(n) { return ['A', 'B', 'C'][(n - 1) % 3]; } console.log(get(1)); // A console.log(get(5)); // B console.log(get(24)); // C

i have a table with these columns: 1st col 2nd col 3rd col 4th col ------------------------------------------------------ | | | 1st Inst | 2nd Inst | | Athletic | 100 | | | | Socio-cultural | 100 | | | | Library | 150 | | | | Medical | 50 | | | | School Organ | 20 | | | | Dev't Fee | 100 | | | ------------------------------------------------------ | Buttons: (ADD) (DEL) | | | ------------------------------------------------------ | | |___Input____|___Input____| ------------------------------------------------------ the values on the 1st and 2nd column are generated using php from the database. this table is a dynamic table wherein the number of the columns can increase or decrease by pressing the buttons. and at the bottom of the table i have input fields that can also increase as the columns of the table increases. what i want is that when i input a value on the input fields, it will be process in a calculation together with the values each row in the 2nd column and that output will be written on the corresponding row of the 3rd/4th column depending on which input field contains the initial value. example is like these: 1st col 2nd col 3rd col 4th col ------------------------------------------------------ | | | 1st Inst | 2nd Inst | | Athletic | 100 | 200 | | | Socio-cultural | 200 | 400 | | | Library | 300 | 600 | | | Medical | 400 | 800 | | | School Organ | 500 | 1000 | | | Dev't Fee | 600 | 1200 | | ------------------------------------------------------ | Buttons: (ADD) (DEL) | | | ------------------------------------------------------ | | | 2 | | i have no problem in the calculation part...what my problem is how can i output the values on the corresponding columns. here is the php code for retrieving the values for both 1st and 2nd col. $stmt = $pdo->prepare('SELECT * FROM miscfeelist'); $stmt->setFetchMode(PDO::FETCH_ASSOC); $stmt->execute(); $result = $stmt->fetchAll(); if (count($result)){ foreach ($result as $r){ echo '<tbody id="tb"><tr> <td align="center">'.$r['MiscFee_Name'].'</td> <td align="center" valign="middle" class="value">'.$r['MiscFee_Value'].'</td> <td> </td> <td class="dwn"> </td> <td class="dwn"> </td> </tbody></tr>'; } } else { echo "No Record in the Database."; } here is the input field: <tr> <td align="center"> </td> <td align="center" valign="middle" bgcolor="#FF9900"><input class="inst" type="text" style="border:thick" size="12" onkeyup="MiscFeeColl()" placeholder="1st" value="0"></td> <td align="center" valign="middle" bgcolor="#FF9900"><input class="inst" type="text" style="border:thick" size="12" onkeyup="MiscFeeColl()" placeholder="2nd" value="0"></td> </tr> here is my code for the calculation: for(var i = 0; i < theOddOnes.length; i++){ //rows for(var l = 0; l < res.length; l++){ inst = theOddOnes[l].value; fund165 = (MiscFee/GrandTot()*inst); fund165 = +fund165.toFixed(2); //columns Miscfee123 = (parseFloat(val[l].innerHTML)/MiscFee*fund165); Miscfee123 = +Miscfee123.toFixed(2); document.getElementsByClassName("dwn")[l].firstChild.nodeValue = Miscfee123; } } the output of these calculation is these: 1st col 2nd col 3rd col 4th col ------------------------------------------------------ | | | 1st Inst | 2nd Inst | | Athletic | 100 | 200 | 400 | | Socio-cultural | 200 | 600 | 800 | | Library | 300 | 1000 | 1200 | | Medical | 400 | | | | School Organ | 500 | | | | Dev't Fee | 600 | | | ------------------------------------------------------ | Buttons: (ADD) (DEL) | | | ------------------------------------------------------ | | |___2________|____________| ------------------------------------------------------ my code is displaying it horizontally.and i've been working on this for the las two weeks..i cant seem to make it to work..pls help..
