I have a database that contains a PERSONNEL table, a VISIT table, and a STARSHIP table.
I am trying to generate a single column list of the personnel that are from Vulcan (PERSONNEL.PLANET) and all starships that have visited Vulcan (VISIT.PLANET). VISIT.SHIP and STARSHIP.REGISTRY columns contain the ships identifiers. How would I accomplish this? I am just beginning sql so please be nice ;)
trouble with this...
i have a table that looks like this....
orderid=1 ordernumber=1 customernumber=1 product=1
orderid=2 ordernumber=1 customernumber=1 product=2
orderid=3 ordernumber=2 customernumber=2 product=5
how can i combine by the actual order
in other words 1 actual order has more then 1 orderid, i need this data more or less in 1 table or query for my form, i think.
if you know what im talking about, because i dont think i even do, haha, please help
thanks in advance for your time and understanding with my noob question.

Hi,
I have came across a situation -
When there are no indices on the tables and if we force SQL server to use the "Nested Loop" joins, the query becomes very slow. Since there are no indices then Nested loop join should not be used.
The background for this problem is -
Analysis services is sending some query to SQL server while doing the cube processing. SQL server is using Nested loop joins even though there are no indices on any of the tables. Is there any way by which we can force the SQL server/Analysis services not to use Nested loop joins since there are no indices in any of the tables.
regards,
datta.
i'm running the following code on Ms SQL Server 2000, Query Analyzer to analyze the result of Nested Loop Join.
SET STATISTICS PROFILE ON
GO
SELECT pdN.ProductID, pdN.ProductName,
spN.CompanyName, spN.ContactName
FROM dbo.ProductsNew pdN
INNER JOIN dbo.SuppliersNew spN
ON pdN.SupplierId = spN.SupplierId
GO
but the execution plan give me the following result :-
http://i31.photobucket.com/albums/c366/i3lu3fun/executionplan.jpg
instead of using nested, why does it using hash join? is there anything wrong with my code?
Could Any body Please give me one example of each of three types of joins that is
Merge Join
Hash Join
Nested join
If your prediction join is to a SQL datasource, you can easily write a SQL query which returns a nested table like:
SELECT
Predict([Subcategories],2) as [Subcategories]
FROM
[SubcategoryAssociations]
NATURAL PREDICTION JOIN
(SELECT
(SELECT 'Road Bikes' AS Subcategory
UNION SELECT 'Jerseys' AS Subcategory
) AS Subcategories
) AS t
What about if your datasource is a cube? Is there some special MDX syntax similar to the SQL syntax above? Or do you have to utilize the SHAPE/APPEND syntax as follows?
SELECT t.*, $Cluster as ClusterName
FROM [MyModel]
PREDICTION JOIN
SHAPE {
select [Measures].[My Measure] on 0,
[My Dimension].[My Attribute].[My Attribute].Members on 1
from MyCube
}
APPEND (
{
select [Measures].[Another Measure] on 0,
NON EMPTY [My Dimension].[My Attribute].[My Attribute].Members
*[Product].[Product].[Product].Members on 1
from MyCube
}
RELATE [[My Dimension]].[My Attribute]].[My Attribute]].[MEMBER_CAPTION]]]
TO [[My Dimension]].[My Attribute]].[My Attribute]].[MEMBER_CAPTION]]]
)
AS [My Nested Table] AS t
ON [MyModel].[Product].[Product] = t.[My Nested Table].[[Product]].[Product]].[Product]].[MEMBER_CAPTION]]]
Hello,
I have this INNER JOIN that is fine to show all possible combinations. But I need to show only rows that have one or more Null values in tbIntersect.
Should I use nested LEFT JOINT? How?
This is the SQL statement:
sSQL = "SELECT DISTINCT tbCar100.Car100_ID, tbCar100.Description100 AS [Caractéristique 100], " & _
"tbCar200.Car200_ID, tbCar200.Description200 AS [Caractéristique 200], " & _
"tbCar300.Car300_ID, tbCar300.Description300 AS [Caractéristique 300], " & _
"tbCar400.Car400_ID, tbCar400.Description400 AS [Caractéristique 400], " & _
"tbCar500.Car500_ID, tbCar500.Description500 AS [Caractéristique 500], " & _
"tbCar600.Car600_ID, tbCar600.Description600 AS [Caractéristique 600], " & _
"tbCar700.Car700_ID, tbCar700.Description700 AS [Caractéristique 700], " & _
"tbProducts.Prod_ID, tbProducts.PartNumber AS [Part Number] , tbProducts.Description AS [Description] , tbProducts.DateAdded AS [Date] " & _
"FROM tbProducts INNER JOIN (tbCar700 INNER JOIN (tbCar600 INNER JOIN (tbCar500 INNER JOIN (tbCar400 INNER JOIN (tbCar300 INNER JOIN (tbCar100 INNER JOIN " & _
"(tbCar200 INNER JOIN tbIntersect ON tbCar200.Car200_ID = tbIntersect.Car200_ID) " & _
"ON tbCar100.Car100_ID = tbIntersect.Car100_ID) ON tbCar300.Car300_ID = tbIntersect.Car300_ID) ON tbCar400.Car400_ID = tbIntersect.Car400_ID) ON tbCar500.Car500_ID = tbIntersect.Car500_ID) ON tbCar600.Car600_ID = tbIntersect.Car600_ID) ON tbCar700.Car700_ID = tbIntersect.Car700_ID) ON tbProducts.Prod_ID = tbIntersect.Prod_ID " & _
";"
Here is the content of the tbIntersect table:
Car100_ID Car200_ID Car300_ID Car400_ID Car500_ID Car600_ID Car700_ID Prod_ID ID
1 1 1 1 1 1 1 1 1
1 2 1 1 1 1 1 19
1 3 1 1 1 1 1 20
I need to return the rows that have null data, ex: second row because Prod_ID is NULL and third row because Car300_ID is NULL. In fact I need the data from the other joint tables that correspond to these ID fields.
Thanks
i have been trying to determine which is the most efficient, with regards to speed and efficiency, between a view and a common/nested table expression when used in a join.
i have a query which could be represented as index view or a common table expression, which will then be used to join against another table.
the indexed view will use indexes when performing the join. is there a way to make the common table expression faster than an indexed view?
do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like
SELECT ... ,CASE enddate WHEN null then 1 else 0 END calcd name
FROM...
WHERE ... and calcd name in (@variable)
I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table.
The makeid and orderdate belong to the OrderDetails table.
The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
I'm using SQL Server 2005.
A piece of software I wrote starting timing out on a query that left outer joins a table to a view. Both the table and view have approximately the same number of rows (about 170000).
The table has 2 very similar columns, one is a varchar(1) and another is varchar(100). Neither are included in any index and beyond the size difference, the columns have the same properties. One of the employees here uses the varchar(1) column (called miscsearch) to tag large sets of rows to perform some action on. In this case, he had set 9000 rows miscsearch value to "g". The query then should join the table and view for all rows where miscsearch is set to g in the table. This query takes at least 20 minutes to run (I stopped it at this point).
If I remove the "where" clause and join all rows in the two tables, the query completes in about 20 seconds. If set the varchar(100) column (called descrip) to "g" for the same rows set via miscsearch, the query completes in about 20 seconds.
If I force the join type to a hash join, the query completes using miscsearch in about 30 seconds.
So, this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER HASH JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
and this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE descrip = 'g' ORDER BY balance DESC
But this does't:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
What should I be looking for here to understand why this is happening?
Thanks,

I am having trouble with the following query.
Important Tables:
Product (table of products)
--ProductID
--ProductName
ProductCategories (Associates a Product with one or more categories)
--ProductID
--CategoryID
Category (table of categories that a product may fall under)
--CategoryID
--CategoryName
Information:
Basically I have a product that falls into two categories. Therefore there are two records in the ProcuctCategories Table. I am trying to create a query that will find all products that are in categories 1 & 2.
Attempted Solution:
SELECT * FROM Product
WHERE (ProductID IN (SELECT CategoryID FROM ProductCategories WHERE CategoryID =1))
AND
(ProductID IN (SELECT CategoryID FROM ProductCategories WHERE CategoryID =2))
This returned zero records though it should have returned the product that is in categories 1&2.
I would appreciate any help available.
Thank you,

View 1 Replies View RelatedHello Everyone,I am trying to create a query for the purpose of a nested repeater relation. The information needs to be pulled from one table. I have shortened the columns to the ones that are required.table - PagesIDPageNameParentPageIDSo, take the following example:ID 14, PageName - Service A, ParentPage ID = 6ID 15, PageName - Service B, ParentPage ID = 6ID 36 PageName - Client 1, ParentPage ID = 14ID 37 PageName - Client 2, ParentPage ID = 14ID 38 PageName - Client 3, ParentPage ID = 15ID 39 PageName - Client 4, ParentPage ID = 15 So, I want to create a query that will get my nested repeater to display as follows:Service A Client 1 Client 2Service B Client 3 Client 4What I have come up with so far is:SELECT * from tbl_Pages WHERE ParentPageID IN (Select ID From tbl_Pages)SELECT p.ParentPageID, p.PageName, p.ID FROM tbl_Pages pThe relation would be based off ParentPageID. I keep getting errors that either there is no unique value or the relation is null. What am I am missing here?

Hi, I have the following scenario that I am not sure how to best tackle. Any
advice or examples is appreciated.
I am creating a stored proc that requires a code to be passed to it. In
return data gathered from 3 different tables will be returned. The big catch
is that 1 of the tables resided in a differenct database.
So, here is the data layout.
Database 1, Table 1 contains the following fields: Job, CustID, ShipID, and
ShipMethod.
Database 2, Table 1 contains CustID, ShipID, Address, City, State, Zip,
etc...
Database 2, Table 2 contains CustID, CustomerName.
So the first question is how should the stored proc look with an input
parameter of "Job" and output of Job, CustID, ShipMethod, ShipID, Address,
City, State, Zip, and CustomerName?
Secondly, which database should the stored proc reside?
Again, any advise, suggestions, pointers, etc. are appreciated.
Hi All,
Can anybody please tell me if a query such as this (Valid in MS Access)
can work in SQL Server:
SELECT Description, Sum(Total) FROM (
SELECT Description, Total FROM Table_A
UNION ALL
SELECT Description, Total FROM Table_B
UNION ALL
SELECT Description, Total FROM Table_C
)
GROUP BY Description
The group of unions work by themselves, but when I try to nest an outer query to do some a Summation(), I have syntax errors.
Any insight would be greatly appreciated. Thank you.
Folks
I have two queries
Select Account_Id , Branch_Cd from Accounts
SELECT SUM (dbo.HOLDING.Shares_Par_Value_Qty * dbo.ASSET.Current_Prc) AS MarketValue
FROM dbo.HOLDING INNER JOIN
dbo.ASSET ON dbo.HOLDING.Property_Num = dbo.ASSET.Property_Num
Group by dbo.HOLDING.Account_ID
Account_ID is the same in both the queries ie in both the tables
Holding and Account.
I need the output like this
Select Account_Id, Branch_Cd, MarketValue from -------
But MarketValue should be calculated exactly in the above method.
How do I combine these two queries. I need it asap.
Help me out.
Thanks
I have the following result set #1 from the query below. As you can see, there are four different provider roles and four different physicians listed for the same case (acctnum). Is there a way I could add a nested select (or other method) which would allow me to list this case as one line item to appear in the manner of result set #2?

Dear All,
I need to create a query to list all the subfolders within a folder.
I have a database table that lists the usual properties of each of the folder.
I have another database table that has two columns
1. Parent folder
2. Child folder
But this table maintains the parent child relationship only to one level.
For example if i have a folder X that has a subfolder Y and Z.
And Y has subfolders A and B.
and B has subfolder C and D
and C has subfolder E and F
The database table will look like
parentfolder child folder
X Y
X Z
Y A
Y B
B C
B D
C E
C F
I want to write a query which will take a folder name as the input and will provide me a list of all the folders and subfolders under it. The query should be based on the table (parent - child) and there should not be any restriction on the subfolder levels to search and report for.
I have been banging my head to do this but i have failed so far. Any help on this will be highly appreciated.
I'd appreciate some help with the issue below - my SQL is a bit rusty and was never that hot to be frank. I'm using SQL Server 2000 (although have a test box with 2005 Express also). I've trawled MSDN and a few forums but can't find the solution (maybe I don't know what I'mm looking for!), so any help would be marvellous...
I have a table with a field called 'IRV' containing a string of comma-separated values. I want to be able to query a point in that string and count the number of times a given value appears. So...as an example, I want to count how many times '1' appears at position 7 in the IRV. I can create SQL to do this as follows:
SELECT COUNT(X) AS is1
FROM myIRVtable
WHERE (SUBSTRING(IRV, 7, 1) = '1')
So far so good. However, it is also possible that the value at position 7 in this string could be '2' (or '3', or '4', etc) - and rather than re-running the query again and again to get these values, I'd like to do it in one hit.
How can I combine all this together - anyone have any brilliant solutions?

Calling procedure with ParentID=14 and Position=89
It's not null value=0
You can see it adding and checking the values and attempting to call itself, but it never seems to get re-called, any ideas?

Hi,
I am trying to limit a result set by ROW_NUMBER. However, I am having problems getting it working.
The following query works fine, and I get a result set with PollID, AddedDate and RowNum columns.
SELECT *, ROW_NUMBER() OVER (ORDER BY Results.AddedDate DESC) AS RowNum FROM
( SELECT DISTINCT p.PollID, p.AddedDate
FROM vw_vs_PollsWithVoteCount p
JOIN vs_PollOptions o ON p.PollID = o.PollID
) AS Results
However, as soon as I add a WHERE condition:
SELECT *, ROW_NUMBER() OVER (ORDER BY Results.AddedDate DESC) AS RowNum FROM
( SELECT DISTINCT p.PollID, p.AddedDate
FROM vw_vs_PollsWithVoteCount p
JOIN vs_PollOptions o ON p.PollID = o.PollID
) AS Results
WHERE RowNum BETWEEN 1 AND 10
The query fails with an ' Invalid column name 'RowNum' ' error.
I have tried using 'Results.RowNum' but I get the same problem.
I don't understand what the issue is. The result set has a column headed 'RowNum' so why can't I apply a WHERE clause to this column? I can apply WHERE to the PollID column, for example, with no problem.
Any help very much appreciated.
Thanks...
I have added some SQL to an Access form which updates the dbo_BM_Map table when the user hits the Apply button. There is a temp table with various fields, two being "Chapter_No" and "Initial_Mapping_Complete" which the update is based on.
I want this update to only apply to chapters that only have one name in the "Initial_Mapping_Complete" column. If a chapter has more than one then the update should ignore it. The attached screengrab shows you. The update should ignore chapter 19 as there are two people (Jim and James) in the Initial_Mapping_Complete field. Here is my code.
pdate dbo_BM_Map inner Join Temp_Progression_Populate
on dbo_BM_Map.Product_ID = Temp_Progression_Populate.Product_ID
Set dbo_BM_Map.Initial_Mapping_Complete = Temp_Progression_Populate.Initial_Mapping_Complete
Where dbo_BM_Map.Chapter_No = Temp_Progression_Populate.Chapter_No
And Temp_Progression_Populate.Initial_Mapping_Complete in
(Select count(Initial_Mapping_Complete), Chapter_No
from Temp_Progression_Populate
Group by Chapter_No
Having Count(Initial_Mapping_Complete) = 1)
Hi,
I have a following query:
select cu.Currencies_ShortName
from dbo.Currencies cu
inner join
(
select p1.Pairs_Shortname as f1, right(p1.Pairs_Shortname,3) as Currency1,
/*v1*/ -- max(SpotBid) as SpotBid, max(SpotAsk) as SpotAsk
/*v2*/ SpotBid, SpotAsk
from dbo.Pairs p1 inner join dbo.PairsQuotes pq1
on p1.Pairs_Id=pq1.Pairs_Id
and pq1.PriceDate=(select max(PriceDate) from dbo.PairsQuotes)
where p1.Pairs_Shortname like 'EUR%'
/*v1*/ -- group by p1.Pairs_Shortname, right(p1.Pairs_Shortname,3)
) as sr
on cu.Currencies_ShortName=sr.Currency1
which would work like /*v2*/, but not like /*v1*/ - there would be a message:
Server: Msg 8624, Level 16, State 3, Line 1
Internal SQL Server error.
Is Group By not manageable in a nested query, or is it some other problem?
thx

My multiple level nested corelated query is not fetching correctresult. It work fine on small set of data, but fails on larger set ofdata. Any clue?Explaining data storing and discussing design would be tough for mehere, still to show you how complex I have created my life, here is thequery:select(SELECT Top 1 RowNSBranchID FROM AssoExtBranchToNSBranchMstM AM-- MMMWHERE AM.RowExtSysID IN(SELECT RowID FROM ExternalSystemMstM WHERE ExtSysID =(SELECT ExtSysID FROM ExternalSystemMstM WHERE SF = 'Active' ANDRowID =(SELECT MAX(RowID) FROM ExternalSystemMstM WHERE MCStatus = 2 ANDExtSysCode = UM.SystemCode)))AND RowExtBranchID IN(SELECT RowID FROM ExternalBranchMstMWHERE ExtBranchID =(SELECT ExtBranchID FROM ExternalBranchMstMWHERE ROWID =(SELECT RowID FROM ExternalBranchMstMWHERE ROWID =(SELECT MAX(ROWID) FROM ExternalBranchMstM WHERE MCStatus = 2 ANDExtBranchCode = UM.UpBranchCodeAND RowExtSysID IN(SELECT RowID FROM ExternalSystemMstM WHERE ExtSysID =(SELECT ExtSysID FROM ExternalSystemMstM WHERE SF = 'Active' ANDRowID =(SELECT MAX(RowID) FROM ExternalSystemMstM WHERE MCStatus = 2AND ExtSysCode = UM.SystemCode))))AND (SF = 'Active'))))AND AM.SF = 'Active'order by AssoID desc,TrackID desc) nsbranchid, UM.*fromTmpInProcessData062005MstM UM
