I am trying to update the table(orders)after calculate the total amount of that order, I successfully calculate the total amount, but I cannot find way to update the table using the result.
code I successfully calculate the total amount:
SELECT orders.orderid,
SUM(ordersdish.quantity*dish.price) AS total
FROM dish
JOIN ordersdish
ON ordersdish.dishid = dish.dishid
JOIN orders
ON orders.orderid = ordersdish.orderid
GROUP BY orders.orderid;
Result:
total amount
Code I tried to update table(orders):
UPDATE orders
SET total = t1.total
FROM (
SELECT orders.orderid,
SUM(ordersdish.quantity*dish.price) AS total
FROM dish
JOIN ordersdish
ON ordersdish.dishid = dish.dishid
JOIN orders
ON orders.orderid = ordersdish.orderid
GROUP BY orders.orderid
)t1
WHERE orders.orderid = t1.orderid;
MySQL said:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'from
(select orders.orderid, SUM(ordersdish.quantity*dish.price)as total
from ' at line 3
And here is the table "orders":
The correct syntax in MySQL use JOIN:
update orders o join
(select od.orderid, SUM(od.quantity * d.price)as total
from dish d join
ordersdish od
on od.dishid = d.dishid
group by od.orderid
) t1
on o.orderid = t1.orderid
set o.total = t1.total;
Note that orders is not needed in the subquery, because the orderid is in orderdish.
Please try this answer.
UPDATE o
SET o.total = t1.total
(SELECT o.orderid, SUM(od.quantity * d.price) AS total
FROM dish AS d
JOIN ordersdish AS od ON od.dishid = d.dishid
JOIN orders AS o ON o.orderid = od.orderid
GROUP BY orders.orderid) t1
WHERE o.orderid = t1.orderid;
I have to create a view in MySQL, this is the code:
CREATE VIEW dashboard_sales AS (
SELECT o.order_id,o.order_date,o.order_status,op.op_status,oi.oi_qty
FROM
order o
LEFT JOIN
order_items oi
ON
o.order_id = oi.order_id
LEFT JOIN
order_payment op
ON
o.order_id = op.order_id
GROUP BY o.order_id
);
but when I execute in phpmyadmin, I get an error:
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'order o
LEFT JOIN
order_items oi
ON
o.order_id = oi.' at line 4
How to solve this problem?
You need a backtick for order
CREATE VIEW dashboard_sales AS (
SELECT o.order_id,o.order_date,o.order_status,op.op_status,oi.oi_qty
FROM `order` o LEFT JOIN order_items oi
ON o.order_id = oi.order_id
LEFT JOIN order_payment op
ON o.order_id = op.order_id
);
When you use the keywords for the name of the tables, you should place the table between the Brackets.
CREATE VIEW dashboard_sales AS (
SELECT o.order_id,o.order_date,o.order_status,op.op_status,oi.oi_qty
FROM
[order] o
LEFT JOIN
order_items oi
ON
o.order_id = oi.order_id
LEFT JOIN
order_payment op
ON
o.order_id = op.order_id
GROUP BY o.order_id
);
I am using the below format to use select and update command in the same query.
UPDATE t
SET t.col1 = o.col1
FROM table1 AS t
INNER JOIN
table2 AS o
ON t.id = o.id
I applied the same concept in my query but it is throwing an error which I am not able resolve. Any idea where I am going wrong here?
update T set T.price = 2*OT.ingredients from Cake as T Inner join (select
A.cakeid, B.price, sum(C.price) ingredients
from
Contain as A
inner join
Cake as B ON A.cakeid = B.cakeid
inner join
Ingredient as C ON C.ingredid = A.ingredid
group by A.cakeid
having B.price <= 2 * sum(C.price) ) as OT on OT.cakeid = T.cakeid
Error Code: 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 Cake as T Inner join (select A.cakeid, B.price, sum(C.price) ingredien' at line 1
The correct syntax in MySQL is:
update Cake T Inner join
(select A.cakeid, B.price, sum(C.price) ingredients
from Contain A inner join
Cake B
ON A.cakeid = B.cakeid inner join
Ingredient as C
ON C.ingredid = A.ingredid
group by A.cakeid
having B.price <= 2 * sum(C.price)
) OT
on OT.cakeid = T.cakeid
set T.price = 2*OT.ingredients ;
I just can't figure out what's wrong with this syntax. I get a #1064 syntax error at the last line.

I've tried to join the tables with RIGHT and LEFT JOINS to see if there is a difference, but they give me the same error.
The different queries within work fine on themselves, but when I join them together in this query I get a syntax error. Does anyone have an idea what I should or shouldn't do?
The 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 '' at line 21"
Here is the reference for Multiple LEFT JOIN

I am getting the following Error
064 - 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 catalog_product_flat_1 a inner join
catalog_product_entity c on a.sku' at line 3
when I try out the below query on phpmyadmin
update a
set a.small_image = b.value
from `catalog_product_flat_1` a
inner join `catalog_product_entity` c
on a.sku = c.sku
inner join `catalog_product_entity_media_gallery` b
on b.entity_id = c.entity_id
I also tryout without using alias but still same issue
The SET clause comes after the JOIN clauses:
UPDATE `catalog_product_flat_1` a
inner join `catalog_product_entity` c
on a.sku = c.sku
inner join `catalog_product_entity_media_gallery` b
on b.entity_id = c.entity_id
SET a.small_image = b.value
