I have two queries:
1) $query = "SELECT `login`, `password` FROM `TEST_ACCS` WHERE `sold` = '0' LIMIT 3";
And then I need change sold to 1 from the result of first query
2) $setQuery = "UPDATE `chrome_ext`.`TEST_ACCS` SET `sold` = '1' WHERE `sold` = '0' LIMIT 3";
How to concat these two queries into one?
I tried
UPDATE `chrome_ext`.`TEST_ACCS` dest, (SELECT `login`, `password` FROM `TEST_ACCS` WHERE `sold` = '0' LIMIT 3) src SET dest.sold = '1' where dest.sold= '0'
But it set sold = 1 to all raws, but need just 3

My Query is very slow returning results. It takes more than 30s (depending a lot on the use of the server). The table has some records.
I cannot divide this table for other reasons. I added this to the query `TYPE` IN (1,3)' and the response time has improved significantly. But it remains very slow.
It is worth mentioning that I have already add an INDEX for the PRODUCT, TYPE, STATUS columns.
Question: How can I speed up the query response time without having to divide it by many tabs and have to use the INNER JOIN?

My Query:
SELECT `PRODUCT`,
SUM(DATE_FORMAT(`REG_DATE`,'%m/%Y') = '11/2020' AND `TYPE` = 1) AS `SUMT1_1`,
SUM(DATE_FORMAT(`REG_DATE`,'%m/%Y') = '12/2020' AND `TYPE` = 1) AS `SUMT1_2`,
SUM(DATE_FORMAT(`REG_DATE`,'%m/%Y') = '01/2021' AND `TYPE` = 1) AS `SUMT1_3`,

SUM(DATE_FORMAT(`REG_DATE`,'%m/%Y') = '04/2021' AND `TYPE` = 3) AS `SUMT3_6`
FROM `MY_TABLE` WHERE
`TYPE` IN (1,3) AND
`STATUS` IN('AVAILABLE','IN PROCESS')
GROUP BY `PRODUCT` ASC
WITH ROLLUP HAVING (`SUMT1_1`+`SUMT1_2`+`SUMT1_3`+`SUMT1_4`+`SUMT1_5`+`SUMT1_6`+`SUMT3_1`+`SUMT3_2`+`SUMT3_3`+`SUMT3_4`+`SUMT3_5`+`SUMT3_6`) >= 1
With an index on some combination of (status,type,reg_date), I would write that query this way:
SELECT product
, DATE_FORMAT(reg_date,'%Y-%m') reg_ym
, type
, COUNT(*) subtotal
FROM my_table
WHERE type IN (1,3)
AND status IN('AVAILABLE','IN PROCESS')
AND reg_date >= '2020-11-01'
AND reg_date < '2020-05-01'
GROUP
BY product
, reg_ym
, type
ORDER
BY product
, reg_ym
, type
...and handle any remaining aspects of the problem in application code
The best solution was given by #Akina (in the comments), and reduced the response time from 30s to 3s (average).
Adding the condition:
`REG_DATE` BETWEEN '20220-11-01' AND '2021-04-30'
But to fit better with my php code i prefer to use:
DATE_FORMAT(`REG_DATE`,'%m/%Y') IN ('11/2020','12/2020','01/2021','02/2021','03/2021','04/2021')
I have working Update query
UPDATE contact
SET ownerid = '1548'
, alloted = '1'
, genby = '1548'
, leadstatus = '-34-,'
, callbackdate = '2019-09-25'
, read = '0'
WHERE id = '22484307'
AND alloted = '0'
AND leadsource = '29'
AND `delete` = '0'
AND ownerid = '0'
AND oldlead != '1'
but when this query is updated by two users at the same time (approx) WHERE condition stops working

It's updating again with the same id and replacing data with millisec difference here is log

I was only checking query execution status not affected status adding that resolved issue thanks all for time mysqli_affected_rows($con) thank you #Solarflare
$updateStatus=mysqli_query($con,"UPDATE `contact` SET `ownerid` = '$loggeduserid',`alloted` = '1',`genby` = '$loggeduserid', `leadstatus` = '-34-,', `callbackdate` = '$date', `read` = '0' WHERE `id` = '$row[0]' AND `alloted` = '0' AND `leadsource` = '$leadS' AND `delete` = '0' AND `ownerid` = '0' AND `oldlead` != '1'") or die(mysqli_error($con));

this is i am getting
SELECT * FROM (`lkt_messages`) WHERE `sender_id` = '1' AND `receiver_id` = '2' OR `sender_id` = '2' OR `receiver_id` = '1' ORDER BY `added_on` DESC
I want like this
SELECT * FROM (`lkt_messages`) WHERE `sender_id` = '1' AND `receiver_id` = '2' OR `sender_id` = '2' AND `receiver_id` = '1' ORDER BY `added_on` DESC
I write the query below.
$cls=MESSAGES_TBL;
$id= $this->session->userdata('user_id');
$condition_query=array('sender_id'=>$replymsg_id,'receiver_id'=>$id);
$condition_query1=array('sender_id'=>$id,'receiver_id'=>$replymsg_id);
$data=$cls::where($condition_query)->or_where($condition_query1);
$result=$data->order_by('added_on', 'DESC')->all();
return $result;
Following change should work:
$condition_query = "(sender_id = $replymsg_id and receiver_id = $id)";
$condition_query1 = "(sender_id = $id and receiver_id = $replymsg_id)";
$data = $cls::where($condition_query)->or_where($condition_query1);
Try this sql query:-
SELECT *
FROM (`lkt_messages`)
WHERE (`sender_id` = '1' AND `receiver_id` = '2')
OR (`sender_id = '2' AND `receiver_id` = '1')
ORDER BY `added_on` DESC
Can somebody refresh my memory on how to build a query for this.
I want to use a list of several names (first and last), to update their rows in the table with same information. for example:
if I have a table set up with the columns:
[first_name],[last_name],[dob],[married_status]
I want to find:
(bob, smith),
(robert, john),
(jane, doe);
and edit their field for [married_status] to 'm'.
how do I structure this search and replace?
Thanks!
Use the IN operator:
UPDATE myTable
SET married_status = 'm'
WHERE (first_name, last_name) IN (
('bob' , 'smith'),
('robert', 'john'),
('jane' , 'doe'))
Code:
UPDATE tablename
SET married_status = 'm'
WHERE
( first_name = 'bob' AND last_name = 'smith' )
OR
( first_name = 'robert' AND last_name = 'john' )
OR
( first_name = 'jane' AND last_name = 'doe' )
You would use UPDATE query:
UPDATE `table`
SET `married_status` = 'm'
WHERE
(`first_name` = 'bob' AND `last_name` = 'smith')
OR (`first_name` = 'robert' AND `last_name` = 'john')
OR (`first_name` = 'jane' AND `last_name` = 'doe')
I have a table named tbl_populations having following fields:
pk_populationid,residence,value,aspect,gender,fk_tbl_states_stateid
I am trying to calculate the difference of rows for two aspects
for e.g.
SELECT fk_tbl_states_stateid, value - (
SELECT value
FROM tbl_populations
WHERE fk_tbl_states_stateid = '16'
AND fk_tbl_districts_districtid = '0'
AND residence = '0'
AND gender = '0'
AND aspect = '2' ) AS difference
FROM tbl_populations
WHERE fk_tbl_states_stateid = '16'
AND fk_tbl_districts_districtid = '0'
AND residence = '0'
AND gender = '0'
AND aspect = '1'
It is working fine as it returns one row
For fetching multiple data that is i want to retrieve all gender values , i have removed the gender from the condition.
SELECT fk_tbl_states_stateid,gender, value - (
SELECT value
FROM tbl_populations
WHERE fk_tbl_states_stateid = '16'
AND fk_tbl_districts_districtid = '0'
AND residence = '0'
AND aspect = '2' ) AS difference
FROM tbl_populations
WHERE fk_tbl_states_stateid = '16'
AND fk_tbl_districts_districtid = '0'
AND residence = '0'
AND aspect = '1'
I am getting Subquery returns more than 1 row error.
How can i get the all results?
SELECT Table11.fk_tbl_states_stateid,Table1.Gender,Table1.value - table2.Value as Diff
From
(SELECT *
FROM tbl_populations
WHERE fk_tbl_states_stateid = '16'
AND fk_tbl_districts_districtid = '0'
AND residence = '0'
AND aspect = '2' ) Table1,
(SELECT value,Gender
FROM tbl_populations
WHERE fk_tbl_states_stateid = '16'
AND fk_tbl_districts_districtid = '0'
AND residence = '0'
AND aspect = '1' ) Table2
Where Table1.Gender = Table2.Gender
use a function for it , should be easy that way
