Having an issue with a join code where the code is executing but is giving me a warning that it is truncating my PROD_INTO_DATE but I noticed that it was entered into the PROD_CAT_CD column.
INSERT INTO `goac`.`product`
(`PROD_ID`,
`PROD_NM`,
`PROD_SKU_NO`,
`PROD_CAT_CD`,
`PROD_PACKAGE_SIZE_NO`,
`PROD_INTRO_DT`)
select distinct
c.PROD_ID, c.PROD_NM, c.PROD_SKU_NO,c.PROD_INTRO_DT,
s.PROD_PACKAGE_SIZE_NO, s.PROD_CAT_CD
FROM ods_product AS c
join ods_sale_large as s
on s.PROD_NM = c.PROD_NM;
select * from product
Where the data is being inserted
The PROD_CAT_CD has data that should be there.
And where the join is coming from it should be fine because it sees the date as date.
from the ods_product
You need to insert the columns in the same order as in the insert column list:
INSERT INTO `goac`.`product` (`PROD_ID`, `PROD_NM`, `PROD_SKU_NO`, `PROD_CAT_CD`, `PROD_PACKAGE_SIZE_NO`, `PROD_INTRO_DT`)
select distinct c.PROD_ID, c.PROD_NM, c.PROD_SKU_NO, s.PROD_CAT_CD, s.PROD_PACKAGE_SIZE_NO, c.PROD_INTRO_DT
from ods_product c join
ods_sale_large s
on s.PROD_NM = c.PROD_NM;
Once I had a colleague that I respected very much. She initially had the same confusion with insert . . . although you list the columns and the select also has column names, the matching is by position rather than by name.
I have an sql query like the following
select *
from register_bs
INNER JOIN spouse_details ON register_bs.reg = spouse_details.reg
WHERE country NOT IN('Australia', 'USA', 'Germany', 'Canada');
This query is displaying correct values for all fields except the 'id' field, it's giving some random id for every data. for example the below data:
when i click on any button of the above data it is going to edit page with different data like below
because the id got is wrong
As there are 900 columns in my register_bs table, I cant use field alias instead of *. Can anyone please tell me how to correct my statement to get the correct id? Thanks in advance
First execute the below query in server and check the values of ID
SELECT register_bs.ID AS ValidateedID, register_bs.*, spouse_details.*
FROM register_bs INNER JOIN spouse_details ON register_bs.reg = spouse_details.reg
WHERE country NOT IN('Australia', 'USA', 'Germany', 'Canada');
Kindly check if the two tables that you have joined have the same column name for their id.
If yes, specify the table first and then the column of the id you want to retrieve.
e.g. register_bs.id
I am trying to group rows in MySQL but end up with a wrong result.
My DB looks like this:
I'm using this query:
SELECT
r_id, va_id,va_klasse,va_periode,
1va_mer,1va_hjem,1va_mot,1va_bil,1va_fit,1va_hand,1va_med,1va_fra,
2va_mer,2va_hjem,2va_trae,2va_bil,2va_sty,2va_mus,2va_med,2va_fra,
3va_mer,3va_hjem,3va_mot,3va_bil,3va_pima,3va_nat,3va_med,3va_fra,
va_lock, va_update
FROM o6hxd_valgfag
WHERE va_klasse IN('7A','7B','7C','8A','8B','8C','9A','9B','9C')
GROUP BY va_id
ORDER BY va_klasse,va_name
This produces a wrong result, where one row is returned with only the first three numbers 123 and not the ones from row two and three.
What I would like is a result where the numbers 123, 321 and 132 are gathered in one line.
I can explain more detailed if this isn't sufficient.
If across those fields there should only be ever one value, you should really have them all in the same record and go about fixing it to insert and update the same record.
Ie I am aware that you database isn't designed correctly
However
To dig you out, you could give this a crack, I suppose.
SELECT
r_id, va_id,va_klasse,va_periode,
MAX(1va_mer),MAX(1va_hjem),MAX(1va_mot),MAX(1va_bil),MAX(1va_fit),MAX(1va_hand),MAX(1va_med),MAX(1va_fra),
MAX(2va_mer),MAX(2va_hjem),MAX(2va_trae),MAX(2va_bil),MAX(2va_sty),MAX(2va_mus),MAX(2va_med),MAX(2va_fra),
MAX(3va_mer),MAX(3va_hjem),MAX(3va_mot),MAX(3va_bil),MAX(3va_pima),MAX(3va_nat),MAX(3va_med),MAX(3va_fra),
va_lock, va_update
FROM o6hxd_valgfag
WHERE va_klasse IN('7A','7B','7C','8A','8B','8C','9A','9B','9C')
GROUP BY va_id
ORDER BY va_klasse,va_name
Your query will not work as intended. Think about this use-case:
what if for row1 (r_id =9), the fields 2va_sty, 2va_mus, 2va_med are not empty and has values?
In such case what should your desired output be? It certainly cannot be the numbers 123, 321 and 132 gathered in one line. Group by is usually used if you want to use aggregate functions executed against a certain field value, in your case va_id.
Not a solution to your problem but i think a better query would be like this (because of the not named columns in the group by clause https://dev.mysql.com/doc/refman/5.5/en/group-by-handling.html):
SELECT
aa.r_id, aa.va_id, aa.va_klasse, aa.va_periode,
aa.1va_mer, aa.1va_hjem, aa.1va_mot, aa.1va_bil, aa.1va_fit, aa.1va_hand, aa.1va_med, aa.1va_fra,
aa.2va_mer, aa.2va_hjem, aa.2va_trae, aa.2va_bil, aa.2va_sty,2va_mus, aa.2va_med, aa.2va_fra,
aa.3va_mer, aa.3va_hjem, aa.3va_mot, aa.3va_bil, aa.3va_pima, aa.3va_nat, aa.3va_med, aa.3va_fra,
aa.va_lock, aa.va_update
FROM o6hxd_valgfag AS aa
INNER JOIN (
SELECT va_id
FROM o6hxd_valgfag
GROUP BY va_id
) AS _aa
ON aa.va_id = _aa.va_id
WHERE aa.va_klasse IN ('7A','7B','7C','8A','8B','8C','9A','9B','9C')
ORDER BY aa.va_klasse, aa.va_name;
Hey guys how do you add two values on separate fields but on the same table
for example:
tblbooks
Quantity
Borrowed
each time a user issue a book to a borrower the Quantity its reduce by 1 and Borrowed is added by 1....
INSERT INTO tablename(field1,field2)
VALUES(v1,v2)
In your case I guess you need to update.
Update yourtable
SET Quantity =Quantity-1,
Borrowed=Borrowed+1
Where userid=1
The way I generally do it is select the row I want to update using LinQ and then just update the values.
For example:
With (From rw In tblBooks Select rw Where rw.Item("MyCondition").ToString = "Condition").First
.Item("Quantity") = .Item("Quantity") - 1
.Item("Borrowed") = .Item("Borrowed") + 1
End With
... I didn't test this code, and it doesn't take into account conversion, error checking, etc, but I hope it conveys the idea...
I am importing data to a table structured: content_id|user_id|count - all integers all comprise the composite primary key
The table I want to select it from is structured: content_id|user_id
For reasons quite specific to my use case, I will need to fire quite a lot of data into this regularly enough to want a pure MySQL solution
insert into new_db.table
select content_id,user_id,xxx from old_db.table
I want each row to go in with xxx set to 0, unless this would create a duplicate key, in which case I wish to increment the number, for the current user_id/content_id combination
Not being a MySQL expert, I tried a few options like trying to populate xxx by selecting from the target table during insert, with no luck. Also tried using ON DUPLICATE KEY to increment counters instead of the usual UPDATE. But it all seemed a bit daft so I thought I would come here!
Any ideas anyone? I have a backup option of wrapping this in PHP, but it would drastically raise the overall running time of the script in which this would be the only non-pure MySQL part
Any help really appreciated. thanks in advance!
--edit
this may sound really awful in principle. but id settle for a way to do it in an update after entering random numbers (i have sent in random numbers to allow me to continue other work at the moment) - and this is a purely dev setup
--edit again
12|234
51|45
51|45
51|45
23|67
would ideally insert
12|234|0
51|45|0
51|45|1
51|45|2
23|67|0
INSERT INTO new_db.table (content_id, user_id, cnt)
SELECT old.content_id, old.user_id, COUNT(old.*) - 1 FROM old_db.table old
GROUP BY old.content_id, old.user_id
this would be the way I would go, so if 1 entry it would put 0 on cnt, for more it would just put 1-2-3 etc.
Edit:
Your correct answer would be somewhat complicated but I tested it and it works:
INSERT INTO newtable(user_id,content_id,cnt)
SELECT o1.user_id, o1.content_id,
CASE
WHEN COALESCE(#rownum, 0) = 0
THEN #rownum:=c-1
ELSE #rownum:=#rownum-1
END as cnt
FROM
(SELECT user_id, content_id, COUNT(*) as c FROM oldtable
GROUP BY user_id, content_id ) as grpd
LEFT JOIN
(SELECT oldtable.* FROM oldtable) o1 ON
(o1.user_id = grpd.user_id AND o1.content_id = grpd.content_id)
;
Assuming that in the old db table (source), you will not have the same (content_id, user_id) combination, then you can import using this query
insert newdbtable
select o.content_id, o.user_id, ifnull(max(n.`count`),-1)+1
from olddbtable o
left join newdbtable n on n.content_id=o.content_id and n.user_id=o.user_id
group by o.content_id, o.user_id;
