Here's a sample of the data I'm pulling from:
+-----+------------+---------+----------+------------+
| id | name | carrier | tracking | date |
+-----+------------+---------+----------+------------+
| 123 | john smith | UPS | abcdefgh | 2018-06-22 |
| 123 | john smith | USPS | 12345678 | 2018-06-23 |
+-----+------------+---------+----------+------------+
The table I'm updating to only has one record for each ID (whereas the table I'm pulling from can have multiple), and I'm trying to get the final output to look like this:
+-----+------------------------------------------+
| id | shipping_info |
+-----+------------------------------------------|
| 123 | 6/22 - UPS abcdefgh 6/23 - USPS 12345678 |
+-----+------------------------------------------+
I have a query and I'm almost there:
update table1
set shipping_info = concat(
DATE_FORMAT(table2.date_time, '\n%c/%e - '),
table2.carrier,
table2.tracking)
where id = '123'
+-----+---------------------+
| id | shipping_info |
+-----+---------------------|
| 123 | 6/22 - UPS abcdefgh |
+-----+---------------------+
So my problem is, when I run the update it only updates the table with the first row of data, but I need to append it with the second row as well.
you should group_concat the concatenated string eg:
select id, group_concat(concat(date,'-' , carrier,'-', tracking))
from my_table
group by id
and for update
update my_update_table m
inner join (
select id, group_concat(concat(date,'-' , carrier,'-', tracking)) my_col
from my_table
group by id
) t on m.id = t.id
set m.shipping_info = t.my_col

I got working code from three queries but I would like to combine them into one or two. Basically I am checking if a provided phone number exists in table contacts or leads as well as if it exists as a secondary number in customfieldsvalues (not all leads have a customfield value though). I am using a CRM system based on CodeIgniter.
What I want to do (non-correct/hypothetical query):
SELECT * FROM contacts OR leads WHERE phonenumber = replace(X, '-', '')
OR leads.id = customvaluefields.relid AND cfields.fieldid = 41 AND cfields.value = X
Tables
table : contacts
+-------+----------------+----------------+
| id | firstname | phonenumber |
+-------+----------------+----------------+
| 1 | John | 214-444-1234 |
| 2 | Mary | 555-111-1234 |
+-------+----------------+----------------+
table : leads
+-------+-----------+---------------------+
| id | name | phonenumber |
+-------+-----------+---------------------+
| 1 | John | 214-444-1234 |
| 2 | Mary | 555-111-1234 |
+-------+-----------+---------------------+
table : customvaluefields
+-------+-----------+-------------+-----------+
| id | relid | fieldid | value |
+-------+-----------+-------------+-----------+
| 1 | 1 | 41 | 222333444 |
| 2 | 1 | 20 | Management|
| 3 | 2 | 41 | 333444555 |
+-------+-----------+-------------+-----------+
If I understand what you are trying to, maybe UNION ALL would work. This is something to get you started:
SELECT C.ID, C.FirstName, C.Phonenumber
FROM Contacts C
JOIN CustomValueField CVF
ON c.ID = CVF.RelID AND
CVF.ID = 41
AND REPLACE(Phonenumber,'-','') = cvf.Value
UNION ALL
SELECT L.ID, L.FirstName, L.Phonenumber
FROM Leads L
JOIN CustomValueField CVF
ON L.ID = CVF.RelID AND
CVF.ID = 41
AND REPLACE(Phonenumber,'-','') = cvf.Value
I'm joining the contacts and leads tables to CustomeValueField in each query and then UNION them together along with the WHERE clause in each. I'm sure it's not 100% correct for what you need, but should get you headed to a solution. Here is more information: https://dev.mysql.com/doc/refman/8.0/en/union.html
I have a DB table
frequency table as follows
(companyid, task, and frequency) is unique key
| companyid| task |frequency | date |
| -------- | ----- | ------- | ----- |
| 123 | abc | Day | 03-03-2020 |
| 123 | def | Week | 09-03-2020 |
| 456 | abc | Week | 10-03-2020 |
| 456 | klm | Week | 12-03-2020 |
History table as follows PRIMARY KEY ("companyid", "RECORDNO")
| companyid| RECORDNO | STAGE | STATE |
| -------- | ----- | ------- | ----- |
| 123 | 12 | 1 | P |
| 456 | 13 | 2 | A |
| 123 | 13 | 1 | S |
Entry table , unique ("companyid", "ID")
| companyid| ID | STATE | task |
| -------- | ----- | ----- | ----- |
| 123 | 12 | Purchased | abc |
| 123 | 13 | Accesible | def |
| 456 | 13 | Store | abc |
| 456 | 14 | Store | klm |
I am running a job that frequently runs every 6 hours.
I have to fetch unique companyids where the state in history table is 'S' and has the task in frequency = task in entry table and recordno is history table = id in entry table and current system date is greater than the date in the frequency table.
The basic need is to process the job(entries from entry table) which has less date than the current system date. (Note the system date is always in UTC and date in frequency table can be configured by the user).
companyid is common in all tables.
I have tried the below query to fetch the result without having the date filters.
Need help in getting the time filter properly.
select distinct cny#
from frequency
where exists
(select 1
from history, entry
where history.companyid = entry.companyid
and history.state='S'
and history.record# = entry.id);
You can use oracle sysdate function to get the current date and time of the database server, and use it in the query.
select distinct companyid
from frequency
where exists
(select 1
from history, entry
where history.companyid = entry.companyid
and history.state='S'
and history.recordno = entry.id)
and sysdate > to_date(date,'DD-MM-YYYY');
Isn't this a simple join of the three tables?
select distinct e.company_id
from entry e
join history h on h.companyid = e.companyid and h,recordno = e.id
join frequency f on f.companyid = e.companyid and f.task = e.task
where f.date < trunc(sysdate)
and h.state = 'S';
or with the criteria in the ON clauses:
select distinct e.company_id
from entry e
join history h on h.companyid = e.companyid and h,recordno = e.id and h.state = 'S'
join frequency f on f.companyid = e.companyid and f.task = e.task and f.date < trunc(sysdate)
;
Usually, though, you'd have a company table, so you wouldn't need DISTINCT:
select * from company where companyid in (select e.companyid from ...);
I have a Mysql table with the following data.
|ID | Date | BillNumber|BillMonth | Amount | Name |AccNum |
| 2 |2015-09-25| 454345 | 092015 | 135.00 |Andrew Good| 735976|
| 3 |2015-09-26| 356282 | 092015 | 142.00 |Peter Pan | 123489|
| 4 |2015-08-11| 312738 | 082015 | 162.00 |Andrew Good| 735976|
| 5 |2015-07-12| 287628 | 072015 | 220.67 |Andrew Good| 735976|
| 6 |2015-06-12| 100756 | 062015 | 556.34 |Andrew Good| 735976|
What I wanted to achieve is to retrieve the data of Andrew Good with AccNum 735976 for the BillMonth of 092015, provided that the user can entry any of his BillNumber(past/current).
If the reason that that row is of interest is because it is the latest of his rows, try:
select *
from tbl t
where name = ( select name
from tbl
where billnumber = 100756 -- can be any of his
)
and date = ( select max(date)
from tbl x
where x.name = t.name
)
(the billnumber can be any of his)
I would like to ask a quick question regarding a mysql query.
I have a table named trans :
+----+---------------------+------+-------+----------+----------+
| ID | Date | User | PCNum | Customer | trans_In |
+----+---------------------+------+-------+----------+----------+
| 8 | 2013-01-23 16:24:10 | test | PC2 | George | 10 |
| 9 | 2013-01-23 16:27:22 | test | PC2 | Nick | 0 |
| 10 | 2013-01-24 16:28:48 | test | PC2 | Ted | 10 |
| 11 | 2013-01-25 16:36:40 | test | PC2 | Danny | 10 |
+----+---------------------+------+-------+----------+----------+
and another named customers :
+----+---------+-----------+
| ID | Name | Surname |
+----+---------+-----------+
| 1 | George | |
| 2 | Nick | |
| 3 | Ted | |
| 4 | Danny | |
| 5 | Alex | |
| 6 | Mike | |
.
.
.
.
+----+---------+-----------+
I want to view the sum of trans_in column for specific customers in a date range BUT ALSO include in the result set, those customers that haven't got any records in the selected date range. Their sum of trans_in could appear as NULL or 0 it doesn't matter...
I have the following query :
SELECT
`Date`,
Customer,
SUM(trans_in) AS 'input'
FROM trans
WHERE Customer IN('George','Nick','Ted','Danny')
AND `Date` >= '2013-01-24'
GROUP BY Customer
ORDER BY input DESC;
But this will only return the sum for 'Ted' and 'Danny' because they only have transactions after the 24th of January...
How can i include all the customers that are inside the WHERE IN (...) function, even those who have no transactions in the selected date range??
I suppose i'll have to join them somehow with the customers table but i cannot figure out how.
Thanks in advance!!
:)
In order to include all records from one table without matching records in another, you have to use a LEFT JOIN.
SELECT
t.`Date`,
c.name,
SUM(t.trans_in) AS 'input'
FROM customers c LEFT JOIN trans t ON (c.name = t.Customer AND t.`Date` >= '2013-01-24')
WHERE c.name IN('George','Nick','Ted','Danny')
GROUP BY c.name
ORDER BY input DESC;
Of course, I would mention that you should be referencing customer by ID, and not by name in your related table. Your current setup leads to information duplication. If the customer changes their name, you now have to update all related records in the trans table instead of just in the customer table.
try this
SELECT
`Date`,
Customer,
SUM(trans_in) AS 'input'
FROM trans
inner join customers
on customers.Name = trans.Customer
WHERE Customer IN('George','Nick','Ted','Danny')
GROUP BY Customer
ORDER BY input DESC;
I have some MySQL results like this:
---------------------------
| name | something_random |
---------------------------
| john | ekjalsdjalfjkldd |
| alex | akjsldfjaekallee |
| alex | jkjlkjslakjfjflj |
| alex | kajslejajejjaddd |
| bob | ekakdie33kkd93ld |
| bob | 33kd993kakakl3ll |
| paul | 3k309dki595k3lkd |
| paul | 3k399kkfkg93lk3l |
etc...
This goes on for 1000's of rows of results. I need to limit the number of results to the first 50 unique names. I think there is a simple solution to this but I'm not sure.
I've tried using derived tables and variables but can't quite get there. If I could figure out how to increment a variable once every time a name is different I think I could say WHERE variable <= 50.
UPDATED
I've tried the Inner Join approach(es) suggested below. The problem is this:
The subselect SELECT DISTINCT name FROM testTable LIMIT 50 grabs the first 50 distinct names. Perhaps I wasn't clear enough in my original post, but this limits my query too much. In my query, not every name in the table is returned in the result. Let me modify my original example:
----------------------------------
| id | name | something_random |
----------------------------------
| 1 | john | ekjalsdjalfjkldd |
| 4 | alex | akjsldfjaekallee |
| 4 | alex | jkjlkjslakjfjflj |
| 4 | alex | kajslejajejjaddd |
| 6 | bob | ekakdie33kkd93ld |
| 6 | bob | 33kd993kakakl3ll |
| 12 | paul | 3k309dki595k3lkd |
| 12 | paul | 3k399kkfkg93lk3l |
etc...
So I added in some id numbers here. These ID numbers pertain to the people's names in the tables. So you can see in the results, not every single person/name in the table is necessarily in the result (due to some WHERE condition). So the 50th distinct name in the list will always have an ID number higher than 49. The 50th person could be id 79, 234, 4954 etc...
So back to the problem. The subselect SELECT DISTINCT name FROM testTable LIMIT 50 selects the first 50 names in the table. That means that my search results will be limited to names that have ID <=50, which is too constricting. If there are certain names that don't show up in the query (due to some WHERE condition), then they are still counted as one of the 50 distinct names. So you end up with too few results.
UPDATE 2
To #trapper: This is a basic simplification of what my query looks like:
SELECT
t1.id,
t1.name,
t2.details
FROM t1
LEFT JOIN t2 ON t1.id = t2.some_id
INNER JOIN
(SELECT DISTINCT name FROM t1 ORDER BY id LIMIT 0,50) s ON s.name = t1.name
WHERE
SOME CONDITIONS
ORDER BY
t1.id,
t1.name
And my results look like this:
----------------------------------
| id | name | details |
----------------------------------
| 1 | john | ekjalsdjalfjkldd |
| 3 | alex | akjsldfjaekallee |
| 3 | alex | jkjlkjslakjfjflj |
| 4 | alex | kajslejajejjaddd |
| 6 | bob | ekakdie33kkd93ld |
| 6 | bob | 33kd993kakakl3ll |
| 12 | paul | 3k309dki595k3lkd |
| 12 | paul | 3k399kkfkg93lk3l |
...
| 37 | bill | kajslejajejjaddd |
| 37 | bill | ekakdie33kkd93ld |
| 41 | matt | 33kd993kakakl3ll |
| 50 | jake | 3k309dki595k3lkd |
| 50 | jake | 3k399kkfkg93lk3l |
----------------------------------
The results stop at id=50. There are NOT 50 distinct names in the list. There are only roughly 23 distinct names.
My MySql syntax may be rusty, but the idea is to use a query to select the top 50 distinct names, then do a self-join on name and select the name and other information from the join.
select a.name, b.something_random
from Table b
inner join (select distinct name from Table order by RAND() limit 0,50) a
on a.name = b.name
SELECT DISTINCT name FROM table LIMIT 0,50
Edited: Ahh yes I misread question first time, this should do the trick though :)
SELECT a.name, b.something_random
FROM `table` b
INNER JOIN (SELECT DISTINCT name FROM `table` ORDER BY RAND() LIMIT 0,50) a
ON a.name = b.name ORDER BY a.name
How this work is the (SELECT DISTINCT name FROMtableORDER BY RAND() LIMIT 0,50) part is what pulls out the names to include in the join. So here I am taking 50 unique names at random, but you can change this to any other selection criteria if you want.
Then you join those results back into your table. This links each of those 50 selected names back to all of the rows with a matching name for your final results. Finally ORDER BY a.name just to be sure all the rows for each name end up grouped together.
This should do it:
SELECT tA.*
FROM
testTable tA
INNER JOIN
(SELECT distinct name FROM testTable LIMIT 50) tB ON tA.name = tB.name
;
