Looking on how to update a part of string.
String looks like this: '0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4'
What I want is to change first 9 numbers of string to 0.
Any suggestions on how to do in only with MySQL?
Quick and dirty if your string format/length is fixed:
-- Concat with hardcode prefix with tail of the string:
SELECT CONCAT("0 0 0 0 0 0 0 0 0 ", SUBSTRING("0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4", 19))
-- Update
UPDATE {TABLE}
SET {COLUMN} = CONCAT("0 0 0 0 0 0 0 0 0 ", SUBSTRING({COLUMN}, 19))
Try this (it is tested):
select
CONCAT(
LEFT('0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4', INSTR('0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4','9')-1)
,'0',
RIGHT( '0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4',CHAR_LENGTH('0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4')-1- CHAR_LENGTH(LEFT('0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4', INSTR('0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4','9')-1)))
)
Assume that s='0 0 0 6 7 2 6 8 6 1 7 5 3 2 4 9 9 4' (and can be every strings)
select
CONCAT(
LEFT(s, INSTR(s,'9')-1)
,'0',
RIGHT(s,CHAR_LENGTH(s)-1- CHAR_LENGTH(LEFT(s, INSTR(s,'9')-1)))
)

I have the following scenario:
columns from A-Z and 100 rows
in each row for the Z column I want to find if the value in A column from the current row exists in the rows above in A column
then if exists, I would like to find if the B column for the matching rows have the cell completed with a value
for all the rows that are matching I would to receive the matching rows in an array list, not as rows or at least to be able to put a value like "mathing"/"not matching"
this should be an array formula
I've tried something like this, only for the first criteria, but somehow it checks only the current row.
=ARRAYFORMULA( IF(ROW(Z2:Z)>2, IF(MATCH(A2:A,$A$2:A&ROW(A2:A)-1),"matching","not matching"),"not matching"))
I check to see if it's the first row (as it has headers), and if it's the first row, then surely it can't have any data matching above
It will be great to have it as a google sheet formula but if it's not possible it could also be a google app script
Try this:
function myfunk() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName("Sheet0");
const osh = ss.getSheetByName("Sheet1");
osh.clearContents();
const dsr = 2;
const vs = sh.getRange(dsr, 1, sh.getLastRow() - dsr + 1, sh.getLastColumn()).getDisplayValues();
let o = [];
vs.forEach((r, i) => {
if (i > 0) {
let as = vs.map(r => r[0]).slice(0, i);// suggested by DoubleUnary
let bs = vs.map(r => r[1]).slice(0, i);//suggested by DoubleUnary
let idx = as.indexOf(r[25]);
if (~idx && bs[idx]) {
o.push(['yes', dsr + i, dsr + idx, r[25], bs[idx]])
} else {
o.push(['no', dsr + i, ~idx ? as[idx] : '', r[25], ~idx ? bs[idx] : '']);
}
}
});
o.unshift(['Value', 'Test Row', 'Result Row', 'Z value', 'B value'])
Logger.log(JSON.stringify(o));
osh.getRange(1, 1, o.length, o[0].length).setValues(o);
}

using mysql without using With CTE ie i need normal sql that sum the balance
Here is the problem. I have four columns that I want to present in a select query.
But, I want the RSV column to have a 10-1 scale instead of its + and - values.
The greatest number +8,6 should get 10. Several of the values in the bottom can have 1.
I have absolutley no idea how to solve this...
Nr is race horses start number.
A race can also contain less than fifteen horses
Nr RPO RSP RSV
1 10 9 +5,3
2 9 10 +8,6
3 8 7 -2,7
4 7 8 +3,8
5 6 4 +4,3
6 5 6 -1,0
7 4 5 +3,3
8 3 1 +6,6
9 2 1 +2,1
10 1 1 +3,8
11 1 3 +2,9
12 1 2 -2,1
13 1 1 +1,0
14 1 1 -1,0
15 1 1 +2,4
Last column shows the output:
Nr RPO RSP RSV RSVOutput
2 9 10 8,6 10
8 3 1 6,6 9
1 10 9 5,3 8
5 6 4 4,3 7
4 7 8 3,8 6
10 1 1 3,8 5
7 4 5 3,3 4

15 1 1 2,4 2
9 2 1 2,1 1
13 1 1 1 1
6 5 6 -1 1
14 1 1 -1 1
12 1 2 -2,1 1
3 8 7 -2,7 1
SELECT *
FROM rank
ORDER BY Nr
You could use something like this:
SELECT
Nr, RPO, RSP, RSV,
CASE WHEN #row>1 THEN #row:=#row-1 ELSE 1 END RSVOutput
FROM
yourtable, (SELECT #row:=11) rows
ORDER BY
RSV DESC
Please see fiddle here.
i have a table
id typesignal close open cont

13 8 5 4 0
i want to display the last row of each kind from the typesignal column.
$this->db->group_by('typesignal');
$query = $this->db->get('signals');
but I need the last row that was create i use
$this->db->group_by('typesignal');
$this->db->order_by("idSignal");
$query = $this->db->get('signals');
but its not working.
The expected output is: 13,12,11,9,8,7,6,5,3,2
i use this query
$this->db->group_by('typeSignal');
$this->db->select_max('idSignal');
$this->db->order_by("idSignal", "DESC");
$query = $this->db->get('signals');
return $query->result_array();
is working the secret is $this->db->select_max('idSignal');
Thanx for the help
