I have 2 tables. 'report' and 'panel_calculation' are the tables.
report contains:
r_zone r_address r_status
=======+==========+============
1 8 0
2 9 0
2 6 0
7 9 0
3 2 0
panel_calculation contains:
p_cal_zone p_cal_address p_status
===========+==============+============
7 9 1
3 2 1
I need to update the r_status column in 'report' table on the basis of 'panel_calculation' table.
so that the final result would be like this:
Final 'report' should be like this:
r_zone r_address r_status
=======+==========+============
1 8 0
2 9 0
2 6 0
7 9 1
3 2 1
I need your suggestion.
you could still join both table even when updating the table.
UPDATE report s
INNER JOIN panel_calculation b
ON s.r_zone = b.p_cal_zone
SET s.r_status = b.p_status
SQLFiddle Demonstration
Try this:
UPDATE report r
INNER JOIN panel_calculation p ON r.r_zone = p.p_cal_zone
SET r.r_status = p.p_status;
SQL Fiddle Demo
As a solution to your problem please try executing below sql query
update report r set r_status=(select p_status from panel_calculation where p_cal_zone=r.r_zone limit 1 )
You can use LEFT JOIN like this:
UPDATE report t1
LEFT JOIN panel_calculation t2
ON t1.r_zone=t2.p_cal_zone
AND t1.r_address=t2.p_cal_address
SET t1.r_status=t2.p_status

I have four tables look like below:
test_case (1='pass',2='fail',3='skip')
id testing_status
1 1
2 3
3 1
4 2
5 3
6 2
7 2
8 3
test_suite_with_case (referenced with test_case_id in test_case table and test_suite_id with test_suite table)
id test_suite_id test_case_id
1 4 1,3,5,2,6,7,8
2 3 2,5,4,6,7
test_suite
id test_suite_name
3 test_1
4 test_2
test_suite_run (referenced with test_suite_id in test_suite table)
id test_suite_id name
1 3 BBH
2 4 CXN
Now i want to run a where query from test_suite_run by id (for example id=2 in test_suite_run) and want a output look like below:
id(test_suite_run) name test_suite_name pass fail skip
1 CXN test_suite_2 2 2 3
I am new in PHP and MySQL.
Try this:
select
tr.id,
tr.name,
ts.test_suite_name,
sum(testing_status = 1) pass,
sum(testing_status = 2) fail,
sum(testing_status = 3) skip
from test_suite_run tr
inner join test_suite ts on tr.test_suite_id = ts.id
inner join test_suite_with_case tsc on ts.id = tsc.test_suite_id
inner join test_case tc on find_in_set(tc.id, tsc.test_case_id) > 0
group by
tr.id,
tr.name,
ts.test_suite_name;
I`ve got the following table in mysql
id|top_id|amount
1 NULL 2
2 NULL 8
3 NULL 4
4 3 7
5 2 8
6 2 4
7 5 5
8 7 1
9 6 6
10 8 6
For the first 3 ids i need to sum up all amounts of its successors to get the following:
id | amount
1 8
2 32
3 11
I guess there should be joins but unfortunately I can`t get the working mysql request. Can somebody help me?
UPD: In php I have the following query:
$tops = $mysqli->query('SELECT * FROM table WHERE top_id IS NULL')
which obviously returns me just 3 top ids and their plain amounts (2, 8 and 4 respectively). Instead of 2, 8 and 4 I need to get 12, 28 and 11 and that`s the problem((
This is the crudest solution... No doubt someone will provide some hints for a more scalable solution shortly (perhaps employing PHP)...
SELECT a.id
, COALESCE(a.amount,0)
+ COALESCE(b.amount,0)
+ COALESCE(c.amount,0)
+ COALESCE(d.amount,0)
+ COALESCE(e.amount,0)
+ COALESCE(f.amount,0) total
FROM my_table a
LEFT
JOIN my_table b
ON b.top_id = a.id
LEFT
JOIN my_table c
ON c.top_id = b.id
LEFT
JOIN my_table d
ON d.top_id = c.id
LEFT
JOIN my_table e
ON e.top_id = d.id
LEFT
JOIN my_table f
ON f.top_id = e.id
WHERE a.top_id IS NULL;
i have two tables. 'listing_messages' and 'listing_message_history'.
listing_messages
=============
message_id listing_id listing_user third_party_user
1 162 7 32
2 162 7 33
3 162 7 12
listing_message_history
======================
listing_message_history message_id is_checked
1 1 0
2 1 1
3 1 1
4 2 0
5 2 1
6 3 0
Search criteria==> listing_user=7, is_checked=1
I want result..
message_id count_of_unread_message_history
12
2 1
3 0
I have made a query is
SELECT count(`lmh`.`message_history_id`) AS COUNT,
`lmh`.`message_id`
FROM `listing_message_history` AS `lmh`
LEFT JOIN `listing_messages` AS `lm` ON `lmh`.`message_id` = `lm`.`message_id`
WHERE `lm`.`third_party_user`=7
AND `lmh`.is_checked=1
GROUP BY `lm`.`message_id`
but it does not returns message_id with count = 0 which message_id do not have is_checked=1
In general, when you use left join, filter conditions on the second table should go in the on clause not the where clause. Try this:
SELECT count(`lmh`.`message_history_id`) AS COUNT,
`lmh`.`message_id`
FROM `listing_message_history` `lmh` LEFT JOIN
`listing_messages` `lm`
ON `lmh`.`message_id` = `lm`.`message_id` AND
`lm`.`third_party_user` = 7
WHERE `lmh`.is_checked = 1
GROUP BY `lmh`.`message_id`;
In addition, you should use the first table for the group by, not the second table.

UPDATE all column values equivalent to another tables column value based on their id
(1 answer)
Closed 8 years ago.
i have two tables
fw_invitations
id moduleid qdetailid
1 1 10
2 2 11
3 3 12
4 7 13
5 8 14
fw_ind_details
id moduleid officeid
10 0 100
11 0 110
12 0 120
13 0 130
14 0 104
the column qdetaild is the primary key in fw_ind_details.what i want to do is want to take the moduleid from fw_invitations table for that particular qdetailid and want to update in fw_ind_details.that is it should be done with an update query.
desired output
fw_ind_details
id moduleid officeid
10 1 100
11 2 110
12 3 120
13 7 130
14 8 104
this is what i tried so far;
UPDATE `fw_ind_details`
SET `moduleid`=(select moduleid
from fw_invitaions fo,fw_ind_details fi
where f0.qdetailid=fi.id
)
i know my approach is wrong,any suggestion will be appreciated.
I am open for the use of PHP.
UPDATE fw_ind_details d
JOIN fw_invitations i ON i.qdetailid = d.id
SET d.moduleid = i.moduleid
To get a particular module ID when there are multiple matches, you can join with a subquery; this example uses the highest module ID:
UPDATE fw_ind_details d
JOIN (SELECT qdetailid, MAX(moduleid) moduleid
FROM fw_invitations
GROUP BY qdetailid) i
ON i.qdetailid = d.id
SET d.moduleid = i.moduleid
Use a join...
UPDATE `fw_ind_details`
JOIN fw_invitations ON fw_ind_details.id = fw_invitations.qdetailid
SET fw_ind_details.moduleid = fw_invitations.moduleid
The SQL to use is:
UPDATE `fw_ind_details` fi
SET `moduleid`=(SELECT moduleid
FROM fw_invitaions fo
WHERE fo. qdetailid =fi.id
)
I have this table:
This selection is is duplicated many times for different var_lines (which pretty much work as one row of data, or respondent for a survey) and set_codes (different survey codes).
With this query:
SELECT
*, COUNT(*) AS total
FROM
`data`
WHERE
`var_name` = 'GND.NEWS.INT'
AND(
`set_code` = 'BAN11A-GND'
OR `set_code` = 'BAN09A-GND'
OR `set_code` = 'ALG11A-GND'
)
AND `country_id` = '5'
GROUP BY
`data_content`,
`set_code`
ORDER BY
`set_code`,
`data_content`
The query basically counts the number of answers for a specific question. Then groups them survey (set_code).
What I need is for each of the grouped data_content answers for GND.NEWS.INT to also show the SUM of all the corresponding GND_WT with the same var_line.
For example if I had this:
data_id data_content var_name var_line
1 2 GND.NEW.INT 1
2 1.4 GND_WT 1
3 2 GND.NEW.INT 2
4 1.6 GND_WT 2
5 3 GND.NEW.INT 3
6 0.6 GND_WT 3
I would get something like this:
data_id data_content var_name var_line total weight
1 2 GND.NEW.INT 1 2 3
5 3 GND.NEW.INT 3 1 0.6
Thanks for any help.
Your requirements are not exactly clear, but I think the following gives you what you want:
select d1.data_id,
d1.data_content,
d1.var_name,
d1.var_line,
t.total,
w.weight
from data d1
inner join
(
select data_content,
count(data_content) Total
from data
group by data_content
) t
on d1.data_content = t.data_content
inner join
(
select var_line,
sum(case when var_name = 'GND_WT' then data_content end) weight
from data
group by var_line
) w
on d1.var_line = w.var_line
where d1.var_name = 'GND.NEW.INT'
See SQL Fiddle with Demo
This Query can be suitable for your specific example:
select st.data_id,
st.data_content,
st.var_name,
st.var_line,
count(st.data_id) as total,
sum(st1.data_content) as weight
from data st
left join data st1 on st1.var_name = 'GND_WT' AND st1.var_line=st.var_line
where st.var_name='GND.NEW.INT'
group by st.data_content
