I am working with our inventory database and I created a query (access 2002 format citrix run server) that counts all items of a type meeting a serviceability status and it runs as I had expected but when I try to display the item name Equipment.Model in the other table which is already left joined via the ID I get the error Tried to execute a query that does not include the specified expression 'model' as part of an aggregate function. I think I would expect to get this if I tried to list something like an asset ID but this is related to the items I am counting. The trouble piece is quoted. The tables are quite large but they are basically the below
Equipment
|EquipmentID|CompanyID|Model|Description|TypeID|...
Inventory
|InventoryID|EquipmentID|Serial|Status|...
SELECT Inventory.EquipmentID, "Equipment.Model", COUNT(*) AS Count
FROM (Inventory LEFT JOIN Equipment ON Inventory.EquipmentID=Equipment.EquipmentID)
WHERE Equipment.TypeID = 14
AND Inventory.Status NOT IN (4,5,6,8)
GROUP BY Inventory.EquipmentID;
SELECT Inventory.EquipmentID, Equipment.Model, COUNT(*) AS Count
FROM Inventory
LEFT JOIN Equipment ON Inventory.EquipmentID=Equipment.EquipmentID
WHERE Equipment.TypeID = 14
AND Inventory.Status NOT IN (4,5,6,8)
GROUP BY Inventory.EquipmentID, Equipment.Model;
You have to use all non aggregate columns in the GROUP BY clause.
You need to include equipment.Model in your group by clause

I have two tables in a SQL Server database - IT_Order and Product. I want to group by the product_id from IT_Order but also select the product name from Product. But I get an error for this query. Please help...
The tables:
The query:
SELECT
Product.product_name, IT_Order.product_id,
COUNT(IT_Order.it_order_id) AS Product_volume
FROM
IT_Order, Product
WHERE
IT_Order.product_id = Product.product_id
GROUP BY
IT_Order.product_id;
I get this error:
Column 'Product.product_name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
The error message is clear, you can use column without aggregation, in a GROUP BY, but as every product has only one name(i guess) you can make
SELECT Product.product_name, IT_Order.product_id, COUNT(IT_Order.it_order_id) as
Product_volume
FROM IT_Order JOIN Product
ON IT_Order.product_id = Product.product_id
GROUP BY IT_Order.product_id,Product.product_name;
also please use in future JOIN for your table, as they are around for 30 years now.
I have broken my head with syntax error response from Access Jet engine.
I have three tables.
First one "tblMstItem" is the master table for Item details contains two columns "colITemID" PK and "colItemName"
Second one "tblStocks" is the table where the purchases are maintained. This table has a column "colRQty" which keeps the quantity of the particular item purchased. "colItemID" FK from "tblMstItem"
Third one "tblSales" is the table where the sales are maintained. This table has a column "colSoldQty" which keeps the quantity of the particular item sold. "colItemID" FK from "tblMstItem"
Therefore "colItemID" is common in all the three tables and has links created.
My requirement is I need all the Items listed in the "tblMstItem" table columns are "colItemID" "colItemName" and if there is any item purchased or any item sold should be shown as sum of that particular item.
I have used Left Join shown in the following select statement but it always giving me an error message.
Select statement as follows:
SELECT
i.colItemID,
i.colItemName,
s.rqty,
n.soldqty
from tblMstItem i
left join
( select sum( colRQty ) as rqty from tblStocks group by colItemID ) s
on i.colItemID = s.colItemID
left join
( select sum( colSoldQty ) as soldqty from tblSales group by colItemID ) n
on i.colItemID=n.colItemID``
I tried the above given code with many different syntax but every time I get syntax error. It is making me to doubt do MS Access support three table joins, I am sure I am wrong.
See the error Message below
Table columns and table link shown below
I would be very thankful to get any help on this. Access sql please because this I am able to get results in SQL Server.
Thanks in Advance
MS Access has a picky syntax. For instance, joins need extra parentheses. So, try this:
select i.colItemID, i.colItemName,
s.rqty, n.soldqty
from (tblMstItem as i left join
(select colItemID, sum(colRQty ) as rqty
from tblStocks
group by colItemID
) as s
on i.colItemID = s.colItemID
) left join
(select colItemID, sum( colSoldQty ) as soldqty
from tblSales
group by colItemID
) as n
on i.colItemID = n.colItemID;
You also need to select colItemID in the subqueries.
I am fairly new to SSRS and SQL Server and I need help with the following issue:
I have two tables. One contains the time stamped record of purchases of one single product by a small group of customers. The other table contains the time stamped record of price changes for that product.
Table1
PurchaseDateTime - primary key,
CustCode, kgs
Table2
Price, ChangeDateTime
I can display all required information from the two tables in a tablix using the following query:
SELECT input.purchasedatetime,
input.custcode,
input.kgs,
price.price,
price.changedatetime
FROM input
LEFT OUTER JOIN price
ON input.purchasedatetime > price.changedatetime
However, the query correctly returns the results which includes the superseded prices as well. I could hide those rows, but the totals still sum it all. I could group it by the Price.ChangeDateTime as the third subgroup and then filter it on TopN, but the result is the same. The display is correct, the totals are not, which is probably to be expected since the totals are on the higher level grouping.
I cannot apply the conditions for the visibility to the SUM() as it does not allow aggregates and I am hiding on Previous().
I would prefer the query to do the complete work and I have seen that some other databases implement the LIMIT 1 clause, but here this is not supported.
I am still to try the custom code on the report level, but I am not too familiar with VB code.
I am using the SQL Server 2014 Express and Visual Studio 2013 integrated shell as Data Tools or BI
Any help is much appreciated.
you can get maximum change date time for each purchase time using GROUP BY and MAX
These values can be joined further to get price for each purchase time
SQL Fiddle
with cte
as
(
SELECT input.purchasedatetime, MAX(price.changedatetime) as ChangeDateTime
FROM input
LEFT OUTER JOIN price
ON input.purchasedatetime > price.changedatetime
GROUP BY input.purchasedatetime
)
SELECT input.purchasedatetime,
input.custcode,
input.kgs,
price.price,
price.changedatetime
FROM input
JOIN cte
on input.purchasedatetime = cte.purchasedatetime
left join price
on cte.changedatetime = price.changedatetime
I have a program using SQL Server 2005 Express and I need some help looping through 2 tables to calculate inventory.
Table 1: stores all products with the inventory total upon setup
Table 2: stores the transactions against all products from table 1
How can I loop through all items in table 2 and subtract that amount from table 1 counts?
If I have my query like this then I get data for each product
SELECT
ii.ItemNum, ii.ItemName, ii.OzOnHand
FROM
dbo.InventoryItems ii
INNER JOIN
dbo.InventoryLog il ON ii.ItemNum = il.InvItemNum
WHERE
ii.active = 1
I need each occurrence from table 2 to be subtracted from table 1's total amount
This is an example of a join to an aggregated table (I think that is the best way to understand it):
SELECT ii.ItemNum, ii.ItemName, ii.OzOnHand, ii.OzOnHand - coalesce(il.cnt, 0)
FROM dbo.InventoryItems ii LEFT JOIN
(select il.InvItemNum, sum(OzRemoved) as cnt
from dbo.InventoryLog il
group by il.InvItemNum
) il
ON ii.ItemNum = il.InvItemNum
WHERE ii.active = 1;
The subquery groups everything in the log and counts the number of entries. If each entry could affect more than one item, then you would use something like sum(cnt) as cnt instead of count(*).
Then, the query uses a left outer join. This type of join ensures that all inventory items remain, even those with nothing in the log. Finally, the count is subtracted from what is available in set up. The coalesce() is to handle the situation where there are no matches in the log table. To avoid getting NULL, the NULL is turned into a 0.
Thanks for any help in advance, I can't wrap my SQL skills around this one...
I have two tables like this:
Settings
Customerid ViewerLimit
1 50
2 50
Distribution
Customerid ServerIP
1 stream3
1 stream4
2 stream3
I want to calculate the load on each server. A customer divides the load if they have more than one server, so here customer 1 puts a load of 25 on each server. The result I'm trying to get is this:
ServerIP Load
stream3 75
stream4 25
I tried to do a sum function similar to this:
sum(viewerlimit/(count # of servers)) as load group by serverip
But I can't do a sub query within a sum function. There are many customers and possibly many servers per customer so it will become too complex to do manually. I appreciate any input.
Here is uninspired version with count in derived table:
select serverip, sum (viewerlimit/cast (ServerCount as float)) Load
from
(
select customerid, count(*) ServerCount from distribution group by customerid
) a
inner join settings
on a.customerid = settings.customerid
inner join distribution
on settings.customerid = distribution.customerid
group by serverip
Sql Fiddle to play around
UPDATE - an attempt at explanation
Derived tables are used to produce ad-hoc result sets that can be joined to main body of a query. It is placed in from clause and enclosed in parenthesis. You can use anything an ordinary select can use, top, order by, aggregate functions etc. The only thing you cannot use is correlation to a table in main body. Oh, and CTE. Derived table must be aliased.
In previous sample derived table 'a' selects counts of servers by customerid. Main body sees it as a table with CustomerId and ServerCount columns, ready to be used as any column from all listed tables. A join on customerid is performed between settings and 'a'. As this is 1:1 relation (both tables produce single row given a customerid), no duplication occurs.
How about doing a count of servers in a sub query and assign that to a query variable and then use that query variable inside the sum function?
select d.serverip, sum(s.viewerlimit/d.devider)
from (
select customerid, serverip, COUNT(serverip) over (partition by customerid) servercount
from distribution
) d
join settings s
on s.customerid=d.customerid
group by d.serverip
