I work as administrator in one electronic shop we are using OpenCart eCommerce and recently they asked me to add special price to Bulk products and leave it running for some days. Of course i can change it in admin page one by one. The things is how i can change it through phpMyAdmin.
( Opencart Version 2.1.0.1 )
I have 46 products which cost 25€ and i have to add special price to 20€.
Table we have to update price is
oc_product_special
and column we have to update is
oc_product_special.price
Of course we need products which cost 25€ from table
oc_product
to retrieve products from this table and add special price to 20€
The thing is how to connect these two tables so i can add special price which sql query to run so i can achieve this.
oc_product & oc_product_special , update this column oc_product_special.price
I 've tried to run this sql query but i receive error
UPDATE `oc_product_special`.price
SET `oc_product_special`.price = 16.1290
FROM `oc_product`
INNER JOIN `oc_product_special`
ON `oc_product`.product_id =`oc_product_special`.product_id
WHERE`oc_product`.price = 20.1612;
**** Price is without taxes 25€ / 1,24(tax rate) = 20.1612€
Error
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM oc_product INNER JOIN oc_product_special ON oc_product.product_id =' at line 2
Any help is appreciated
** EDIT
Updating my Sql query
UPDATE oc_product_special AS ps
INNER JOIN oc_product op ON ps.product_id = op.product_id
set ps.price = 16.1290
where op.price = 20.1612
but the thing is that 0 rows affected. (Query took 0.0003 sec) , if i run select query with these prices i have results.
select *
from oc_product as op
where op.price=20.1612
Showing rows 0 - 29 (46 total, Query took 0.0010 sec)
***** Updated 2nd time
Firstly i ran
DELETE FROM `oc_product_special`
WHERE product_id IN
(
SELECT product_id
FROM oc_product p
WHERE p.price = 20.1612
);
so i can " remove any existing specials from these products " , this query ran without any issue
After that i tried to ran Insert query
INSERT INTO `oc_product_special` (`product_special_id`, `product_id`, `customer_group_id`, `priority`, `price`, `date_start`,`date_end`)
VALUES
(
SELECT NULL, 78, 1, 0, 16.1290, 0000-00-00, 0000-00-00
FROM oc_product p
WHERE p.price = 20.1612
);
I adjusted my data concerning to my table's data. But i receive this error
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT NULL, 78, 1, 0, 16.1290, 0000-00-00, 0000-00-00 FROM oc_product p ' at line 4
Your query has no formatting and does not correspond to MySQL standards, you have to pay attention to the following:
After an UPDATE statement one should specify the table to use and not the column
The SET statement only comes after an INNER JOIN
Use suffixes for convenience when joining tables
Correct MySQL query below (change the prices):
UPDATE oc_product_special AS ps
INNER JOIN oc_product op ON ps.product_id = op.product_id
set ps.price = 22 where op.price = 0.00
You need an insert statement rather than an update. You might also consider removing any existing specials from these products beforehand and run a query to clear them like this:
DELETE FROM `oc_product_special`
WHERE product_id IN
(
SELECT product_id
FROM oc_product p
WHERE p.price = 20.1612
);
Then you can select the desired product ids along with other fields and insert them like this:
INSERT INTO `oc_product_special` (`product_special_id`, `product_id`, `customer_group_id`, `priority`, `price`, `date_start`, `date_end`)
VALUES
(
SELECT NULL, product_id, 1, 0, 16.1290, CURDATE(), CURDATE() + INTERVAL 1 DAY
FROM oc_product p
WHERE p.price = 20.1612
);
In this example the special starts today and runs for 5 days. Of course you should adjust the customer_group_id, priority,start_date, andend_date` in my query.

I have the following table(let's call it Sales) structure:
What I would like to do is to fill the field "SalesID" with values resulting from a query I have created in the same DB. This query reflects the table structure so I was thinking to connect the two using the ID.
Basically, I am trying with scripts of this forms:
UPDATE Sales
SET SalesID = ( SELECT SalesIDCalc FROM (SELECT Sales.ID, Sales.[Email Address], Sales.[Points], IIf([Points] >80,"Super","Normal") AS SalesIDCalc FROM Sales) AS q
WHERE Sales.ID = q.ID);
but I am nowhere near the solution. Do you have any idea on how to proceed?
EDIT: Now I get the Error 'Operation must use an updateable table'
I think you want UPDATE with a correlated subquery:
UPDATE Sales
SET SalesID = (SELECT SalesIDCalc
FROM (MyQuery) as q
WHERE Sales.ID = q.ID
);
I am a new in PL/SQL. After hours of learning, I have some
I have a few curious questions. Example I have a SQL statement like this:
SELECT ShipperName, OrderID, NumberOfOrders, ...
FROM Orders
Can we declare a variable that hold the "list select" like list_select = 'ShipperName, OrderID, NumberOfOrders, ... '
And then replace the select statement with the "list select" we was declared?
SELECT list_select
FROM Orders
And other question, Can we reduce the SQL statement like the Image . I was try this in Oracle SQL Developer, the compiler is ok but when I ran the test I was got an error "by segment".
Any help is appreciated and thank for help.
For your first question, You may search for "EXECUTE IMMEDIATE" statement which is used for dynamic query execution. So you may try something like below -
EXECUTE IMMEDIATE 'SELECT ' || YOUR_COMMA_DELIMITED_COLUMNS_LIST || ' FROM Orders';
For 2nd, Please post the sample data and expected result.
For your second question: You don't want joins here, because you only select from table1. You rather want [NOT] EXISTS or [NOT] IN. E.g.:
SELECT orderid, clientid
FROM orders o
WHERE EXISTS -- We are looking for orders containing expensive items
(
SELECT null
FROM orderposition op
WHERE op.orderid = o.orderid
AND op.price > 1000
)
AND -- and the client ...
(
NOT EXISTS -- ... must have paid all their invoices (there exists no unpaid invoice)
(
SELECT null
FROM invoices i
WHERE i.clientid = o.clientid
AND i.paid_date IS NULL
)
OR clientid IN -- ... or be known as reliable client (they are in the set of reliable ones)
(
SELECT c.clientid
FROM clients c
WHERE c.reliable = 'YES'
)
);
tables
Hi, I'm looking to update the last column in a blank table. Picture shows input and desired output. Trying to pick the largest date where workorder and state match.
I've tried a couple different codes:
UPDATE mytable
SET mytable.orderstartdate = MAX(table2.earliestdate)
FROM mytable as table2
WHERE (mytable.workorder = table2.workorder AND
mytable.state = table2.state)
;
"Syntax Error (missing operator) in query expression 'MAX(table2.earliestdate) FROM mytable as table2'."
UPDATE mytable
SET mytable.orderstartdate = (
SELECT max(earliestdate)
FROM mytable as table2
WHERE (mytable.workorder = table2.workorder AND
mytable.state = table2.state)
)
;
"Operation must use an updateable query"
Edit - click tables link for image.
Write PL/SQL Code.
First, select DISTINCT WorkOrder and State and capture in variables.
Now, Iterate the list and Write a query to get max date i.e. max(date) using work_order and State in where clause. Capture the
date.
Now, In the same loop write update query setting max(date) and workorder and State in where clause.
UPDATE table A
SET A.orderstartDate = (SELECT max(earliestdate)
FROM table B
WHERE A.WorkOrder = B.WorkOrder
GROUP BY WorkOrder)
not sure if access supports correlated subqueries but if it does...
and if not...
UPDATE table A
INNER JOIN (SELECT WorkOrder, max(OrderStartDate) MOSD
FROM Table B
GROUP BY WorkOrder) C
ON A.WorkOrder = C.workOrder
SET A.OrderStartDate = C.MOSD

I am trying to Set the value of AmountOwed in my TransactionDetail table based on a formula using fields from TransactionDetail and SalesDetail tables. The inner Select query works and returns the expected value(s). The fields in use are of the following types:
TotalTender - money
PriceEntered - money
TaxRate - float
----- SQL Query -----
Update [POSDatabase].[dbo].[TransactionDetail]
Set AmountOwed =
(Select (TotalTender - (Select sum(PriceEntered+(PriceEntered*TaxRate*.01))
from POSDB.dbo.SalesDetail as Sales
where Sales.TransactionID = Trans.ID))
From POSDB.dbo.TransactionDetail as Trans
Where TransactionDetail.ID = Trans.ID)
Where ID = 4207
----- End SQL Query -----
When I run this query it says it affected 1 row, but when I try to view the table (Select * from Table), the query just spins. Oddly enough, if i scroll down, it has displayed all the records up to 5-6 less than the ID identified in this query.
I thought maybe I was having a data type mismatch, but same thing happens after a CONVERT or CAST has been done to change the result to a money type.
Any suggestions out there?
I am having a hard time following your query but I think something like this might work if I am understanding correctly.
;with s (TransactionID, total) as (
select TransactionID, sum(PriceEntered+(PriceEntered*TaxRate*.01))
from [POSDB].[dbo].[SalesDetail]
group by TransactionID
)
update td
set amountOwed = td.TotalTendered-s.total
from [POSDatabase].[dbo].[TransactionDetail] td
join s on td.id = s.TransactionID
where td.id = 4207
This query doesn't work
SELECT * FROM Catalogue WHERE Catalogue.ID IN (
SELECT ID_catalogue FROM Categories WHERE Categories.Product_type='xxx'
)
Error Code : 1064
You have an error in
your SQL syntax near 'SELECT
ID_catalogue FROM Categories WHERE
Categories.Product_type='xxx' ) ' at
line 2
Ok, that's because I am using a very old MySQL version.
What I am trying to get is
SELECT * FROM Catalogue WHERE Product_type='xxx' OR Catalogue.ID IN (
SELECT ID_catalogue FROM Categories WHERE Categories.Product_type='xxx'
)
Is there any equivalent for that?
Thank you for all your comments.
If you're using mysql version <= 4.0 - then it is the reason, since subqueries were added in 4.1
SELECT c.*,
g.ID_catalogue
FROM Catalogue c
LEFT JOIN Categories g ON g.ID_catalogue = c.ID
AND g.Product_type='xxx'
HAVING ID_catalogue IS NOT NULL
OR Product_type = 'xxx'
You should add composite index ID_catalogue + Product_type for table Categories AND index Product_type for table Catalogue to have this query performed fast
There is nothing wrong with your query. It is the version of MySQL that is more than likely your problem.
