CROSS APPLY Vs OUTER APPLY Example Messed Up?

Nov 27, 2007

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.)

Multiple Cross Apply

Nov 14, 2006

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

Cross Apply Issue (Last Call) :)

May 28, 2008

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?

Count Slowness Using CROSS APPLY

May 13, 2008



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 !

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;

I like to know is there another approach with CTE and or Cross Apply I can use instead?

How Do I Write An OUTER APPLY Without A Table Function?

Nov 1, 2006

I'd like to select the last unshipped order, or if none is open, the last shipped order, for each customer. I noticed that all the examples on line for OUTER APPLY involve table-valued functions, but I have read (in a book I don't have here) that a subquery can work. The following shows what I want, but it isn't valid syntax:
SELECT c.CustomerName, oa.OrderNumber, oa.Status
  FROM Customers c
  OUTER APPLY (
    SELECT TOP 1 CustomerID, OrderNumber,
    CASE WHEN ShipDate IS NULL
         THEN 'due ' + CAST(DueDate AS VARCHAR)
         ELSE 'shipped ' + CAST(ShipDate AS VARCHAR)
         END AS Status,
    CASE WHEN ShipDate IS NULL
         THEN DueDate + 1000 -- Give open orders priority.
         ELSE ShipDate
         END AS SortOrder
    ORDER BY SortOrder
              ) AS oa ON oa.CustomerID = c.CustomerID

Find Nearest Date Record Without Cross Apply

Oct 13, 2012

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.

SQL Server 2012 :: Using Cross Apply To UNPIVOT Data

Jan 15, 2014

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!)

SQL Server 2008 :: Cross Apply With Parameterized Function?

Sep 9, 2015

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.

T-SQL (SS2K8) :: How To Vary Column Names In Cross Apply Based On Different Columns In Each Table

Feb 26, 2015

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.

SQL Server 2012 :: CROSS APPLY Returning Records From Left Recordset Even When No Matching Record In Right One

Oct 7, 2014

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.

Sp3a Does Not Seem To Apply

Feb 26, 2004

I am trying to install sql server sp3a. I checked the version before and after the sp is applied, and it shows:

8.00.194

Now, according to the sp3a readme:

http://support.microsoft.com/default.aspx?scid=/support/servicepacks/SQL/2000/SP3ReadMe.asp

the following versions should show:

SQL Server 2000 Original Release 8.00.194 RTM
Database Components SP1 or Desktop Engine SP1 8.00.384 SP1
Database Components SP2 or Desktop Engine SP2 8.00.534 SP2
Database Components SP3 or SP3a, or Desktop Engine SP3 or SP3a 8.00.760 SP3

This would imply that after installing sp3a and restarting, the version reported should now be 8.00.760. However, it still shows 8.00.194. So it appears to have not really installed, althought the sp3a installation ran without incident. So, how can I get the sp3a to not just act like it installed, but actually get it to install? Also, I have shut down all mssql services and rebooted, applied patch, and rebooted again. Doesn't help.
Also, if it is really installing, is there another way to tell?

Anyway, I really need to be able to install sp3a to see if it fixes another problem I'm having. Unfortunetly, since I can't even tell if the sp3a is installing, I can't tell if it really doesn't help or not. Thanks.
