Is there a better way to write the following simple SQL Server 2005 update statement? This just seems a bit messy inefficient.
UPDATE QuotationItem
SET Recurring_Cost =
(SELECT TOP (1) Recurring_Cost
FROM Products
WHERE (Remote_ID = QuotationItem.Product_ID))
WHERE (Quotation_ID = 115)
Thanks,
Nick
How About using a join
UPDATE QuotationItem
SET Recurring_Cost = p.recurring_cost
FROM QuotationItem q join Products p on q.Product_ID = p.Remote_ID
WHERE q.Quotation_ID = 115
Is your TOP 1 really needed? If it is, since you don't specify an ordering, you've got pretty random results from your query anyway! If it is not really necessary, this will do:
UPDATE q
SET Recurring_Cost = p.RecurringCost
FROM QuotationItem q
INNER JOIN
Products p
ON p.Remote_ID = q.Product_ID
WHERE q.Quotation_ID = 115

I have written a SQL query that joins two tables and calculates the difference between two variables. I want a while loop iterate through the code and do the procedure for a list of organizations numbers orgnr.
Use Intra;
drop table #Tabell1
go
select Månad = A.Manad, Intrastat = A.varde, Moms = B.vardeutf
into #Tabell1
From
IntrastatFsum A
join
Momsuppg B
on A.Orgnr = B.Orgnr
where A.Orgnr = 165564845492
AND A.Ar = 2017
AND B.Ar = A.AR
--AND A.Manad = 11
AND A.Manad = B.Manad
AND A.InfUtf = 'U'
order by A.Manad
select *, Differens = (Intrastat - Moms)/ Moms from #Tabell1
Where do I put the while loop and how should I write it? I don't have a lot of experience with SQL so any help is appreciated.
wasnt clear at all when posting this question was in a big hurry, so sorry guys for that. But what im trying to do is:
This code just runs trough some data, calculates the difference in % for a special company. Each month we get a list of companies that show high standard deviation for some variables. So we have to go through them and compare the reported value with the taxreturn. What im trying to do is write a code that compares the values for "Intra" which is the reported value and " Moms" which is reported tax value. That part i have already done what i need to do now is to insert a loop into the code that goes through a list instead where i have stored the orgnr for companies that show high std for some variables.I want it to keep a list of the companies where the difference between the reported values and taxreturn is high, so i can take an extra look at them. Because sometimes the taxreturn and reported value to ous is almost the same, so i try to remove the most obvious cases with automation
I don't think you need a loop in your query.
Try changing this where-clause:
where A.Orgnr = 165564845492
To this:
where A.Orgnr in (165564845492, 123, 456, 678)
just remove A.Orgnr = 165564845492 in where clause, there is no need of loop
Use Intra;
drop table #Tabell1
go
select Månad = A.Manad, Intrastat = A.varde,Moms = B.vardeutf
into #Tabell1
From
IntrastatFsum A
join
Momsuppg B
on A.Orgnr = B.Orgnr
where A.Ar = 2017
AND B.Ar = A.AR
--AND A.Manad = 11
AND A.Manad = B.Manad
AND A.InfUtf = 'U'
order by A.Manad
select *, Differens = (Intrastat - Moms)/ Moms from #Tabell1
Question is not clear (to me)
select Månad = A.Manad, Intrastat = A.varde, Moms = B.vardeutf
, Differens = (A.varde - B.vardeutf) / B.vardeutf
From
IntrastatFsum A
join
Momsuppg B
on A.Orgnr = B.Orgnr
AND A.Orgnr in (165564845492, ...)
AND A.Ar = 2017
AND A.Manad = B.Manad
AND A.InfUtf = 'U'
order by A.Manad
I have a table of measurements from weather stations, with station names (in Hebrew):
I also have created a table of those weather stations with their latitudes and longitudes:
I've written a query that should update the first table with the lat/longs from the second, but it's not working:
update t1
set t1.MeasurementLat = t2.Latitude,
t1.MeasurementLong = t2.Longitude
from [dbo].[Measurements] as t1
inner join [dbo].[StationCoords] as t2 on t1.StationName like t2.Station
I think there is a problem with the way the station name is being read, and perhaps something to do with encoding, because this query brings back an empty result, too:
SELECT TOP (5) *
FROM [dbo].[Measurements]
WHERE [StationName] = 'אריאל מכללה';
Any ideas?
Your example names are not the same. Perhaps this will work:
update m
set MeasurementLat = sc.Latitude,
MeasurementLong = sc.Longitude
from dbo.[Measurements] m join
dbo.[StationCoords] sc
on m.StationName like sc.Station + '%';
I am trying to create a MySQL statement that I can put in a php script to update the weight on a few thousand products in magento 1.9.
This is the statement I currently have:
UPDATE dp_catalog_product_entity_decimal AS ped JOIN dp_eav_attribute AS ea ON ea.entity_type_id = 10 AND ea.attribute_code = 'weight' AND ped.attribute_id = ea.attribute_id SET ped.value = 8 WHERE ped.entity_id = P1000X3;
It was partially taken from another post so I am not sure if it will work at all but I currently have the error "#1054 - Unknown column 'P1000X3' in 'where clause'"
I am not that great with sql joins and I dont really know the magento databse at all so any help to get this statement to work is much apreciated.
Thanks.

The correct SQL to update the weight of a product with a specific SKU in Magento is this (replace YOUR-MAGENTO-SKU with the sku of the item you want to update, and the 8 with the weight value).
UPDATE catalog_product_entity_decimal AS cped
JOIN eav_attribute AS ea ON ea.entity_type_id = (SELECT entity_type_id FROM eav_entity_type WHERE entity_type_code = 'catalog_product')
LEFT JOIN catalog_product_entity AS cpe ON cpe.entity_id = cped.entity_id
AND ea.attribute_code = 'weight'
AND cped.attribute_id = ea.attribute_id
SET cped.value = 8
WHERE cpe.sku = 'YOUR-MAGENTO-SKU';
In your case, you have the table prefix dp_, and the product sku P1000X3, so the correct SQL for you would be:
UPDATE dp_catalog_product_entity_decimal AS cped
JOIN dp_eav_attribute AS ea ON ea.entity_type_id = (SELECT entity_type_id FROM dp_eav_entity_type WHERE entity_type_code = 'catalog_product')
LEFT JOIN dp_catalog_product_entity AS cpe ON cpe.entity_id = cped.entity_id
AND ea.attribute_code = 'weight'
AND cped.attribute_id = ea.attribute_id
SET cped.value = 8
WHERE cpe.sku = 'P1000X3';
After running this, be sure to reindex your Magento Indexes.
Do your Magento tables have the prefix dp_? Make sure of this.
Also on this part:
WHERE ped.entity_id = P1000X3;
ped.entity_id will be an integer value (number).
I'm not sure where you got P1000X3, but using that won't work (it's a string value). Even so, strings should be wrapped with a single quotes ', like this:
'P1000X3';
I am trying to translate a QueryExpression that is in some existing code into a T-SQL select statement.
I've run across the following statement and I'm having trouble understanding what they mean by a Natural Join:
linkEntity1.JoinOperator = JoinOperator.Natural;
Would this be equivalent to an Inner Join in T-SQL? Googling has not been much help.
Here's the rest of the QueryExpression Code:
QueryExpression query = new QueryExpression();
query.EntityName = "showinfo";
ColumnSet columns = new ColumnSet();
columns.Attributes = new String[] { "company" };
query.ColumnSet = columns;
query.Criteria = new FilterExpression();
query.Criteria.FilterOperator = LogicalOperator.And;
ConditionExpression condition1 = new ConditionExpression();
condition1.AttributeName = "company";
condition1.Operator = ConditionOperator.NotNull;
query.Criteria.Conditions = new ConditionExpression[] { condition1 };
LinkEntity linkEntity1 = new LinkEntity();
linkEntity1.JoinOperator = JoinOperator.Natural;
linkEntity1.LinkFromEntityName = "show";
linkEntity1.LinkFromAttributeName = "showid";
linkEntity1.LinkToEntityName = "showintegration";
linkEntity1.LinkToAttributeName = "showcode";
linkEntity1.LinkCriteria = new FilterExpression();
linkEntity1.LinkCriteria.FilterOperator = LogicalOperator.And;
ConditionExpression condition2 = new ConditionExpression();
condition2.AttributeName = "showend";
condition2.Operator = ConditionOperator.Null;
linkEntity1.LinkCriteria.Conditions = new ConditionExpression[] { condition2 };
query.LinkEntities = new LinkEntity[] { linkEntity1 };
There is no equivalent in SQL Server of a natural join where table intersect is based on column names by the RDBMS.
I'm glad of that because it is at best ambiguous and at worst dangerous. JOINs should be explicit. Examples why:
having a InsertedBy column in both tables (quite common): should we have to prefix with the table name to remove ambiguity?
future DDL that add columns that change JOIN semantics
See
Natural join in SQL Server
SQL Server - lack of NATURAL JOIN / x JOIN y USING(field)
Edit:
It looks like natural join means "don't repeat the column in the output" (like USING in MySQL would do) according to the JoinOperator Enumeration.
If I understand this (debatable!) it's misleading. Especially when I read the "LeftOuter" narrative..
A natural join compares all columns in the two tables that have the same column names. It's equivalent to an inner join with the matching columns explicitly listed.
Yes - the natural join is inner join - so you can write:
select * from tab1, tab2 where tab1.col1 = tab2.col1
as
select * from tab1 inner join tab2 on tab1.col1 = tab2.col1
I would appreciate some help with an UPDATE statement.
I want to update tblOrderHead with the content from tblCustomer where the intDocumentNo corresponds to the parameter #intDocumentNo. But when I run the my statement, the order table is only updated with the content from the first row of the customer table.
What is the problem with my logic?
I use Microsoft SQL Server.
Thanks,
Stefan
UPDATE dbo.tblOrderHead
SET dbo.tblOrderHead.intCustomerNo = #intCustomerNo ,
dbo.tblOrderHead.intPaymentCode = dbo.tblCustomer.intPaymentCode,
dbo.tblOrderHead.txtDeliveryCode = dbo.tblCustomer.txtDeliveryCode,
dbo.tblOrderHead.txtRegionCode = dbo.tblCustomer.txtRegionCode,
dbo.tblOrderHead.txtCurrencyCode = dbo.tblCustomer.txtCurrencyCode,
dbo.tblOrderHead.txtLanguageCode = dbo.tblCustomer.txtLanguageCode
FROM dbo.tblOrderHead
INNER JOIN dbo.tblCustomer ON dbo.tblOrderHead.intOrderNo = #intDocumentNo
Solution
If anyone as stupid as me out there thing the same thing, this is how you solve it:
UPDATE dbo.tblOrderHead
SET dbo.tblOrderHead.intCustomerNo = #intCustomerNo ,
dbo.tblOrderHead.intPaymentCode = dbo.tblCustomer.intPaymentCode,
dbo.tblOrderHead.txtDeliveryCode = dbo.tblCustomer.txtDeliveryCode,
dbo.tblOrderHead.txtRegionCode = dbo.tblCustomer.txtRegionCode,
dbo.tblOrderHead.txtCurrencyCode = dbo.tblCustomer.txtCurrencyCode,
dbo.tblOrderHead.txtLanguageCode = dbo.tblCustomer.txtLanguageCode
FROM dbo.tblOrderHead
INNER JOIN dbo.tblCustomer ON dbo.tblOrderHead.intCustomerNo = dbo.tblCustomer.intCustomerNo
AND dbo.tblOrderHead.intOrderNo = #intDocumentNo
Problem is that, you are not specifying the condition on which the 2 tables tblOrderHead, tblCustomer need to be joined!
you need something like
INNER JOIN dbo.tblCustomer
ON dbo.tblOrderHead.someColumn = dbo.tblCustomer.someColumn
and dbo.tblOrderHead.intOrderNo = #intDocumentNo
