Problem With Cross Apply Query
Nov 10, 2006
Hey guys. This is one of the queries pasted from BOL. I'm having problems excuting this query. The problem lies in the CROSS APPLY part. When I copy this query and run it in SSMS, it gives me an error saying 'Incorrect syntax near .' It doesn't like the qs.sql_handle part. If I remove that and pass the actual handle in for some query, it works. Can someone please tell me what I'm doing wrong?????? Also, I've sp1 installed on my SQL Server 2005 Enterprise, just in case if this matters. Below is the query pasted which is giving me problems. Thank you.
SELECT TOP 5 total_worker_time/execution_count AS [Avg CPU Time],
SUBSTRING(st.text, (qs.statement_start_offset/2)+1,
((CASE qs.statement_end_offset
WHEN -1 THEN DATALENGTH(st.text)
ELSE qs.statement_end_offset
END - qs.statement_start_offset)/2) + 1) AS statement_text
FROM sys.dm_exec_query_stats AS qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) AS st
ORDER BY total_worker_time/execution_count DESC;

Hi... I'm reading the MS Press 70-442 Self-Paced Training kit, and I'm having problems with this example.
I'd like help getting it to work correctly, or understand why it is isn't working the way I planned.
On page 67, the lab is about the APPLY operator (CROSS APPLY and OUTER APPLY). I first have to input a sample table-valued function into the AdventureWorks database:
Code Block
CREATE FUNCTION fnGetAvgCost(@ProdID int)
RETURNS @RetTable TABLE (AvgCost money)
AS
BEGIN
WITH Product(stdcost)
AS
(
SELECT avg(standardcost) as AvgCost
FROM Production.ProductCostHistory
WHERE ProductID = @ProdID
)
INSERT INTO @RetTable
SELECT * FROM Product
RETURN
END
and then run a sample T-SQL statement
Code Block
SELECT p.Name, p.ProductNumber,
Convert(varchar, cost.AvgCost,1) AS 'Average Cost'
FROM Production.Product p
CROSS APPLY fnGetAvgCost(p.ProductID) AS cost
WHERE cost.AvgCost IS NOT NULL
ORDER BY cost.AvgCost desc
My problem is with the WHERE clause... According to page 56, CROSS APPLY returns only rows from the outer table that produces a result set, so why do I need to explicitly filter NULL values?
When I remove the WHERE clause, the query retrieves lots of NULL AvgCost values.
Again, according to page 56, it is the OUTER APPLY that returns all rows that return a result set and will include NULL values in the columns that are returned from the table-valued function.
So, in short, I don't see the difference between CROSS APPLY and OUTER APPLY, using this example, when I remove the WHERE clause?
(Please refrain from introducing another example into this question.)

Hi,
Why am I getting a different numbers of distinct ids in those queries?
USE AdventureWorks
go
Declare @myXml as xml
set @myXml = '
<lol>omg</lol>
<lol>rofl</lol>
';
select locations.*, T.c.value('.','nvarchar(max)') from
(
select newid() as Id
from Production.ProductModel
where ProductModelID in (7, 8)
) as locations cross apply @myXml.nodes('(/lol)') T(c);
select mytable.* , T.c.value('.','nvarchar(max)') from
(
select newid() as Id
union
select newid()
) as mytable cross apply @myXml.nodes('(/lol)') T(c);
Thanks,

I have a question, is there any equivalent for the CROSS APPLY operator in SQL server 2000?
I have the following code in SQL Server 2005 and it works fine, but I need an equivalent code in SQL server 2000.
SELECT *
FROM Customers Cust CROSS APPLY dbo.GetAccountAttributes(Cust.AccountNo) Att
what I need is to join a function and passing it a dynamic parameter.

Good Afternoon,
I'm attempting to leverage SQL's new 'APPLY" operator and I guess I don't fully understand it proper usage.
This is a relatively simple request, first i want to count the models produced within a valid period of time. The first 'Cross Apply' gets the valid starting and ending dates and looks ups the number of models produced for the period of time. This section of code works perfectly fine.
The problem appears to be with the second "Cross Apply". What I'm attempting to accomplish is to count all models produced, regardless of time frame.
When executed the query appears to go into an loop and I end up canceling out the request.
Any ideas where I went wrong?? Any help is greatly appreciated!
select b1.model as Model
,b1.MinDate as Mfg_Str_Date
,b1.MaxDate as Mfg_End_Date
,Count(b2.Model+B2.Serial) as Mfg_Date_Valid
,Count(b3.Model+B3.Serial) as All_Units
from (select b.model, min(b.build_date) as MinDate ,max(b.build_date) as MaxDate
from etbl_models_Serial as b
group by b.model) as b1
--These are Units produced within Valid Window
cross apply (select b2.model,b2.Serial
from etbl_Production as b2
where b2.Model = b1.Model
and b2.Mfg_Date between b1.MinDate and b1.MaxDate) as b2
--These are all units produced
cross apply (select b3.model,b3.Serial
from etbl_Production as b3
where b3.Model = b2.Model) as b3
Group by b1.Model, b1.MinDate, b1.MaxDate
Order by b1.Model

I can't figure out what can be causing this.
When I use this query
Select top 1000 a.EmployeeID,b.*
from #TmpActiveEmployeesWSeverance a
cross apply
dbo.fn_Severance_AccountItemsTable(a.EmployeeID,a.BenefitTypeID,null,null,null,null) b
order by a.EmployeeID,a.BenefitTypeID
It runs 4 seconds
If I try to insert the results into anything It runs > 5 minutes (I have yet to let it finish)
I have tried the two following pieces of code, both with the same results
Select top 1000 a.EmployeeID,b.*
into #Tmp
from #TmpActiveEmployeesWSeverance a
cross apply
dbo.fn_Severance_AccountItemsTable(a.EmployeeID,a.BenefitTypeID,null,null,null,null) b
order by a.EmployeeID,a.BenefitTypeID
--and
Insert Into TRP_ActiveEmployeesWSeverance
(EmployeeID
,PK
,BeginningBalance
,BenefitInterestRowID
,BenefitInterestID
,BenefitTypeID
,DateReceived
,InvoiceDate
,Amount
,Hours
,Fraction1
,Fraction2
,Interest
,InterestAmount
,StartDate
,EndDate
,PeriodApplied
,Offset
,Reserve
,Account
,BenefitClosedID
,PaidOut
,ClosedAccount
,ai
,ClosedDate
,StartAgain
,PartialDividend
,PartialFraction
,SameDateCount)
Select top 1000 a.EmployeeID,b.*
from #TmpActiveEmployeesWSeverance a
cross apply
dbo.fn_Severance_AccountItemsTable(a.EmployeeID,a.BenefitTypeID,null,null,null,null) b
order by a.EmployeeID,a.BenefitTypeID
Any thoughts as to what can be disrupting this?

Will the order of inner joins and cross apply effect the results of a query?
Example:
FROM dbo.vw_Info v
CROSS APPLY dbo.usf_LastFee(v.StoreID, v.AgreementID, v.CustomerID, ABS(v.PrePaymentBalance), cp.ConfirmationNo) lf
INNER JOIN dbo.Customers c
[Code] ....
I want to change the position of doing "CROSS APPLY". Will it effects query results?

Hello,
is it possible to use CROSS APPLY like this:
SELECT [x]
FROM [Order] CROSS APPLY (SELECT .OrderNo + 3) [x]
i know you need [x].* but is it possible to use a function so that only [x] is needed?
thx in advance for help

Hello,
I am doing a report that uses paging and in order to optimize it, i used row_number() so i could make it return x rows per page, so, in order to compute the number of pages needed, i have to count the total number of rows, which gets very slow because i'm using a cross apply with a table-valued function. Is there any way so i can get the number of rows processed by row_number() so i dont have the need to do count?
Thanks in advance !

Table :
ChangeID ChangeDate EquipmentID ModuleID EquipStatus
1 12/9/08 230 1789 Normal
2 13/9/08 450 1245 Normal
3 17/9/08 230 1789 Open
4 21/9/08 230 1899 Open
5 21/9/08 450 1674 Normal
6 22/9/08 450 2364 Normal
Given a date, what module was each equipment item in on that date?How do I get the date of the nearest previous event from a list like this? I got a query from one of the post in this Forum only using Cross Apply to find the nearest record from the above table based on Date i.e.
SELECT outerT.*
FROM your_table AS outerT
CROSS APPLY
(
SELECT TOP 1
equipment_id
, change_date
FROM your_table AS innerT
WHERE innerT.change_date <= @point_in_time
AND innerT.equipment_id = outerT.equipment_id
ORDER BY change_date DESC
) AS applicable_records
WHERE applicable_records.change_date = outerT.change_date
The problem is I need to get this query without using Cross Apply as i need to use the same for the LINQ which doesn't support Cross Apply.

I was reading Kenneth Fisher's and Dwain Camps' articles on unpivoting using cross apply... And I can actually get them to work....
CREATE TABLE #TxCycle(
Cycle INT NOT NULL,
PatientID INT NOT NULL,
ALOPECIA TINYINT,
Causality1 TINYINT,
Relatedness1 TINYINT,
[Code] ....
The one thing I was wondering was this: how do I extract the symptom names from the field list without knowing them all beforehand? Dwain does this
-- DDL and sample data for UNPIVOT Example 2
CREATE TABLE #Suppliers
(ID INT, Product VARCHAR(500)
,Supplier1 VARCHAR(500), Supplier2 VARCHAR(500), Supplier3 VARCHAR(500)
,City1 VARCHAR(500), City2 VARCHAR(500), City3 VARCHAR(500))
Can this be adapted if you don't know all the column names beforehand? (Likely not). Back in the dark ages, when I was working on a database like this, it was in Access, and I could loop over the fields collection and evaluate each field name. (Yes, I know you're not supposed to store information in field names, but I inherited that mess!)

I'm unable to reproduce the error. when they upgrade their OS and SQL EXPRESS to a more recent version the error disappears.
The error is: Incorrect syntax near '.'
the query in question resembles this:
Select column1, column2
from Table1 T
cross apply function(t.column4,t.column5) F
where column3 = 'XXXX'
I made sure that the compatibility level is greater than 90 this error is happening on SQL2005 SP2 as well as SQL2008 with SP2 (but not all clients are suffering from the same problem)
Can it be the .net framework? Although the machines had .net framework 3.52.
Can the OS be an issue? The OS' seem to be old, Windows Server 2008 SP2
I've tried to reproduce the error by setting up virtual machines with same OS and SQL but, again, can't reproduce.

I am using CROSS APPLY instead of UNPIVOT to unpivot > one column. I am wondering if I can dynamically replace column names based on different tables? The example code that I have working is based on the "Allergy" table. I have thirty more specialty tables to go. I'll show the working code first, then an example of another table's columns to show differences:
select [uplift specialty], [member po],[practice unit name], [final nomination status]
,[final uplift status], [final rank], [final uplift percentage]
,practiceID=row_number() over (partition by [practice unit name] order by Metricname)
,metricname,Metricvalue, metricpercentilerank
[code]....
Rheumatology Table:The columns that vary start with "GDR" and [GDR Percentile Rank] so I'm just showing those:
GDR (nvarchar(255), null)
GDR Percentile Rank (nvarchar(255), null)
GDR PGS (nvarchar(255), null)
GDR Rank Number (nvarchar(255), null)
PMPM (nvarchar(255), null)
[Code] ....
These are imported from an Excel Workbook so that's why all the columns with spaces for now.

Following is the query that I'm running:
create table a (id int, name varchar(10));
create table b(id int, sal int);
insert into a values(1,'John'),(1,'ken'),(2,'paul');
insert into b values(1,400),(1,500);
select *
from a
cross apply( select max(sal) as sal from b where b.id = a.id)b;
Below is the result for the same:
idname sal
1John500
1ken500
2paulNULL
Now I'm not sure why the record with ID 2 is coming using CROSS APPLY, shouldn't it be avoided in case of CROSS APPLY and only displayed when using OUTER APPLY.
One thing that I noticed was that if you remove the Aggregate function MAX then the record with ID 2 is not shown in the output. I'm running this query on SQL Server 2012.

I’ve never written a query with multiple APPLY joins before and I’m running into some troubles with my first one. The below SQL statement runs within 10 seconds if I comment out either one of the APPLY joins and its corresponding field columns. However, when I try to execute with both APPLY joins, the query runs indefinitely. The longest I’ve waited before cancelling it is 90 minutes.
Now, I know there are probably other ways I could write this query to get me the results I’m looking for. I’m posting this on the board because I’m curious about finding out why multiple APPLY joins could cause SQL Server to run away. I’m hoping to gain some insight so that I can better understand how APPLY joins work so that in case I have a big need to do this again in the future (without suitable workarounds) I can code it correctly.
Here are some things I’ve tried so far…
1.Changed the States table into a subquery that only returns a single state
2.Change all the references inside the APPLY subqueries so that they had different aliases (just in case they were conflicting with each other).
3.Changed the CROSS applies to OUTER applies. States has 50 records and only 32 have matching permit data so the 18 extra iterations using OUTER APPLY don’t impact performance any when an APPLY is used by itself.
SELECT s.state_name
, COUNT(DISTINCT DUPS.PermitNumber) AS NumOfDupPermits
, SUM(DistinctPermits) AS DistinctPermits
FROM States S
CROSS APPLY (SELECT w.StateID, COUNT(*) as DistinctPermits
[Code] ....

Hi all.
we have a department that has an access database with a bunch of queries in it. They want us to convert it to sql server. One of the queries is a cross-tab query. Is there an easy way to create this in sql? the column headings are the value of column from a table. This could change each month that they run it. How do I make the column heading a variable? I'm guessing a stored procedure would be best. Does anyone have any suggestions?
Thanks so much.

Hi - I have what I think is a "simple problem".We currently have a database table that stores ItemProperties byItemID, PropertyID and Value. (The PropertyID references another tablefor property names and types.)This ItemProperties table is indexed and provides a flexible way ofstoring our item metadata. However, I would now like to returnrecordsets to the application layer that list these properties incolumn fashion, grouped by ItemIDI have seen that most cross-tab queries examples assume numerical dataand are based around using SUM and the GROUP BY phrase. But our datais a mixture of string and numbers (of various formats) and so GROUPBY is not an obvious solution. I have tried using CASE in the selectlist but this returns one row for each property with one column havingthe correct value, and all the other colums are NULL. I cannot thinkof how to combine these into one full record!!I could achieve the desired resultset by using a SELECT sub-statementfor every column, but I was hoping there was a more efficient method.Can anyone offer advice on this? It would be most appreciated.Best,Bill

I need it so that I can provide it to our Power users, so that they can use it themselves, instead of coming back to the IT Department.
