editing the display of an existing table - mysql

How to make a data upload request correctly in order to get data from the table in the form I expect?
I have this table:
But am expecting this:


You can use GROUP_CONCAT for this purpose:
SELECT
ID,
GROUP_CONCAT(TitleUid) As TitleUid,
GROUP_CONCAT(Title) AS Title,
GROUP_CONCAT(types) AS types
FROM my_table
GROUP BY ID;
-- ID TitleUid Title types
-- 1 asd,dsa,ssd title1,title2,title3 typeA,typeB,typeC
-- 2 asd,ssf title1,title2 typeB,typeC
-- 3 ssf,xcv,zxc title1,title2,title3 typeA,typeB,typeC

UPDATE statement using GROUP_CONCAT()

I'm attempting to create a single query that UPDATES another table but the SUBQUERY/DERIVED-QUERY that I would use requires me to have them GROUP BY and GROUP_CONCAT().
I was able to get my desired output but to do so I had to create a temporary table to store the "grouped/ concated" data and then push that "re-organized" data to the destination table. TO do so, I have to literally run 2 separate queries one that populates the temp table with the "organized" data in it's fields and then run another UPDATE that pushes the "organized" data from the temp table to the final destination table.
I've created a REPREX that exemplifies what I'm trying to achieve below:
/*
Create a simplified sample table:
*/
CREATE TABLE `test_tbl` (
`equipment_num` varchar(20),
`item_id` varchar(40),
`quantity` decimal(10,2),
`po_num` varchar(20)
)
--
-- Dumping data for table `test_tbl`
--
INSERT INTO `test_tbl` (`equipment_num`, `item_id`, `quantity`, `po_num`) VALUES

--- The data above is a subsample of what I have on the db, what I'm trying to do is to update another table based off this info but with some GROUP_CONCAT()
--- With the data from above, I need to GROUP_CONCAT(item_id),GROUP_CONCAT(quantity), GROUP_CONCAT(po_num) -- grouping by equipment_num field.
---
--- What I'm attempting to do is to do an UPDATE to another table with the GROUPED by equipment_num with and the Group_concats for the fields described above.
---
--- The only way I was able to do what I desired was with a intermediary TEMPORARY table.
---
--- Create the temp table:
--- Since what I need is a "list" of the quantities, I had to do a GROUP_CONCAT(CONCAT(quantity,''))
DROP TABLE __tmp__; CREATE TABLE __tmp__
SELECT equipment_num, GROUP_CONCAT( item_id ), GROUP_CONCAT(CONCAT( quantity , '' ) ), GROUP_CONCAT( po_num )
FROM `test_tbl`
GROUP BY equipment_num
--- Then FINALLY pull the information in the format I desire to the destination table:
UPDATE `dest_tbl` AS ms INNER JOIN `__tmp__` AS isn ON ( ms.equipment_num = isn.equipment_num ) SET ms.item_id = isn.item_id,
ms.piece_count = isn.quantity,
ms.pieces_detail = isn.po_num
I'm trying to create a single queries that generates a derived query that does the group_concat part and then pushes that derived query result to the final destination table.
Any suggestions would be greatly appreciated.
Thank you for your time.

EDIT: Thank you for the replies I've got, but I'm trying to AVOID using the temp table.
I'm trying to AVOID creating a temp table.... I'm wondering how to do it in one go...
I was thinking something along the lines of:
UPDATE dest
INNER JOIN(
SELECT src.equipment_num, GROUP_CONCAT(src.item_id) as item_id,
GROUP_CONCAT(CONCAT(src.quantity)) as quantity,
GROUP_CONCAT(src.po_num) as po_num
FROM `item_shipped_ns` as src
INNER JOIN milestone_test_20221019 as dest ON(src.equipment_num=dest.equipment_num)
WHERE src.importer_id='123456'
GROUP BY src.equipment_num
) as tmp ON(src.equipment_num=tmp.equipment_num)
SET
dest.item_num=tmp.item_id,
dest.piece_count=tmp.quantity,
dest.pieces_detail=tmp.po_num;
Unfortunately, the above doesn't work, I get the following error msg.
#1146 - Table 'fgcloud.dest' doesn't exist
Edit 2: I had a missing brackets in the above which caused a different error, I've fixed it but having issues with the table aliases. The table in question that should be updated is the "milestone_test_20221019" - it is declared as "dest", yet I it says it cannot find it, suggestions? The source table which I need to get the info and aggregate before updating "milestone_test_20221019" is the "item_shipped_ns" and I believe that "tmp" table is the derived/sub-query table alias...

You need to give an alias to the GROUP_CONCAT() so you'll get a column named item_id. It won't use the argument to GROUP_CONCAT() as the name of the resulting column automatically.
CREATE TABLE __tmp__
SELECT equipment_num,
GROUP_CONCAT( item_id ) AS item_id,
GROUP_CONCAT( quantity ) AS quantity,
GROUP_CONCAT( po_num ) AS po_num
FROM `test_tbl`
GROUP BY equipment_num
To do this in a single query without creating the __tmp__ table, just put the query used to create __tmp__ in a subquery in the UPDATE.
UPDATE milestone_test_20221019 AS dest
JOIN (
SELECT equipment_num,
GROUP_CONCAT( item_id ) AS item_id,
GROUP_CONCAT( quantity ) AS quantity,
GROUP_CONCAT( po_num ) AS po_num
FROM item_shipped_ns
GROUP BY equipment_num
) AS src ON dest.equipment_num = src.equipment_num
SET dest.item_id = src.item_id,
dest.quantity = src.quantity,
dest.po_num = src.po_num

Thanks for the assistance, after a few more test and tweaks I was able to achieve what I desired.
Below is an example of how to use an UPDATE with GROUP_CONCAT() as well an implicit-explicit casting for the quantity field.
UPDATE milestone_test_20221019 as dest
INNER JOIN(
SELECT src.equipment_num, GROUP_CONCAT(src.item_id) as item_id,
GROUP_CONCAT(CONCAT(src.quantity,'')) as quantity,
GROUP_CONCAT(src.po_num) as po_num
FROM item_shipped_ns as src
INNER JOIN milestone_test_20221019 as t1 ON(src.equipment_num=t1.equipment_num)
WHERE src.importer_id='4081836'
GROUP BY src.equipment_num
) AS tmp ON(tmp.equipment_num=dest.equipment_num)
SET
dest.item_num=tmp.item_id,
dest.piece_count=tmp.quantity,
dest.pieces_detail=tmp.po_num;
Thank you for the people that commented and assisted me with their inputs.
Best regards,

Select 2 different columns from 2 different tables

I'm trying to select 2 different columns (newsID from the table news and movID from the table movies) so that I can use mysql_num_rows to grab the items in those conditions.
I tried this with the code below, but it is not working. How can I fix it?
$queryy="SELECT newsID FROM ".PREFIX."news WHERE published='1'";
$queryy="UNION (SELECT movID FROM ".PREFIX."movies WHERE activated='2')";
$all=safe_query($queryy);
$gesamt=mysql_num_rows($all);

You're overwriting the variable with the second assignment. Do it all in one string assignment:
$queryy = "SELECT newsID FROM ".PREFIX."news WHERE published='1'
UNION (SELECT movID FROM ".PREFIX."movies WHERE activated='2')";

I need a desired table format in sql

TeacherApprover Table - Table format in Database
TeacherID ApproverID ApproverLevel
15122 4 1
15122 2 2
15122 3 3
i need the result as in select Statement- it should display as below
TeacherID ApproverID ApproverID2` ApproverID3
15122 4 2 3
i tried directly binding in front end but i have some issues after binding like this, So i want to try getting the result in Dataset directly from backend.
please guide me

I think you need approver id by teacher Id.
So I think you can get data using query,
SELECT ApproverID from table_name where teacherID = 15122;
Then handle the result according to your requirement.
Create new table having column as you needed.
insert into that new table .
INSERT INTO table2
(column_name(s))
SELECT column_name(s)
FROM table1;

MySQL INSERT INTO table 1 SELECT table 2 with different column name

I have a table (pdt_1) in database (db_1) and another table (pdt_2) in another database (db_2).
I met pdt_1 and pdt_2 to find pdt_1 products not present and published in pdt_2.
functional code :
SELECT * FROM db_1.pdt_1 AS lm
WHERE lm.product_sku
NOT IN (SELECT DISTINCT product_cip7 FROM db_2.pdt_2)
AND lm.product_publish=‘Y'
finally, I need to insert the result of this query in pdt_2.
However, the structure of pdt_1 and pdt_2 are different.
Example:
- columns's names
- columns's numbers
I also need an auto_increment id for pdt_1 products inserted into pdt_2.
I need help.
NB : sorry for my poor english :(

If you want a new table with just the id and product_sku, try:
INSERT INTO new_table # with id and product_sku from first table
SELECT pdt_1.id,
pdt_1.product_sku
FROM db_1.pdt_1
LEFT JOIN db_2.pdt_2
ON pdt_1.product_sku = pdt_2.product_cip7
WHERE pdt_2.product_cip7 IS NULL
AND pdt_1.product_publish = 'Y'

Get a list of ids not present in a table

I have a list of ids, and I want to query a mysql table for ids not present in the table.
e.g.
list_of_ids = [1,2,4]
mysql table
id
1
3
5
6
..
Query should return [2,4] because those are the ids not in the table

since we cant view ur code i can only work on asumption
Try this anyway
SELECT id FROM list_of_ids
WHERE id NOT IN (SELECT id
FROM table)
I hope this helps

There is a horrible text-based hack:
SELECT
substr(result,2,length(result)-2) AS notmatched
FROM (
SELECT
#set:=replace(#set,concat(',',id,','),',') AS result
FROM (
select #set:=concat(',',
'1,2,4' -- your list here
,',')
) AS setinit,
tablename --Your tablename here
) AS innerview
ORDER BY LENGTH(result)
LIMIT 1;

If you represent your ids as a derived table, then you can do this directly in SQL:
select list.val
from (select 1 as val union all
select 2 union all
select 4
) list left outer join
t
on t.id = list.val
where t.id is null;
SQL doesn't really have a "list" type, so your question is ambiguous. If you mean a comma separated string, then a text hack might work. If you mean a table, then something like this might work. If you are constructing the SQL statement, I would advise you to go down this route, because it should be more efficient.
