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.

See sample data below. I'm trying to count the number of occurrences of strings stored in table @word without a while loop.
DECLARE @t TABLE (Id INT IDENTITY(1,1), String VARCHAR(MAX))
INSERT INTO @t
SELECT 'There are a lot of Multidimensional Expressions (MDX) resources available' AS String UNION ALL
SELECT 'but most teaching aids out there are geared towards professionals with cube development experience' UNION ALL

I am trying to figure out how to pivot a temporary table. I have a table which starts with a date but the number of columns and columns names will vary but will be type INT (Data, col2,col3,col4………….n)
So it could look like
Date , TS-Sales, Budget , Toms sales
01-Jan-14,100,120,300
02-Jan-14,80,150,300
03-Jan-14,100,20,180
Turned to this
01-jan-14, 02-jan-14, 03-jan-14
100,80,100
120,150,20
300,300,180
Or even just the date and a SUM
What I want is to be able to sum al the columns but without knowing the name and the amount columns to start with this is a manually processes. How could I automate this?

I am trying to pivot data based on columns value in year column... but results are not showing up correctly. I want to see all columns after pivot.I want to Pivot based on year shown in the data but it can be dynamic as year can go for last 3 years
I am also using an inner join as i have two amount columns in my code and i want to show both amount columns for all displayed year.I am able to pivot but I need in output all the columns like this Id,MainDate, Year1,Year2,Year3(if any), AMT1 for YR1, AMT2 for Yr1, , AMT1 for YR2, AMT2 for Yr2, AMT1 for YR3, AMT2 for Yr3,
Here is some data:
-- CREATE TABLE [dbo].[TEMP](
--[FileType] [varchar](19) NOT NULL,
--[dType] [char](2) NOT NULL,
--[dVersion] [char](2) NOT NULL,
--[Id] [char](25) NOT NULL,

I have data:
Ticket User Priority
A ME 1
B ME 1
C ME 2
C ME 3
D ME 2
E YOU 2
F YOU 1
G ME 3
H YOU 2
H YOU 3
I ME 1
Essentially if Ticket and User are the same I just want the min priority returned.
SO:
Ticket User Priority
A ME 1
B ME 1
C ME 2
D ME 2
E YOU 2
F YOU 1
G ME 3
H YOU 2
I ME 1
I've tried partition and rank but can't get it to return the right output.

Assuming I have a table similar to the following:
Auto_ID Account_ID Account_Name Account_Contact Priority
1 3453463 Tire Co Doug 1
2 4363763 Computers Inc Sam 1
3 7857433 Safety First Heather 1
4 2326743 Car Dept Clark 1
5 2342567 Sales Force Amy 1
6 4363763 Computers Inc Jamie 2
7 2326743 Car Dept Jenn 2
I'm trying to delete all duplicate Account_IDs, but only for the highest priority (in this case it would be the lowest number).
I know the following would delete duplicate Account_IDs:
DELETE FROM staging_account
WHERE auto_id NOT IN
(SELECT MAX(auto_id)
FROM staging_account
GROUP BY account_id)
The problem is this doesn't take into account the priority; in the above example I would want to keep auto_ids 2 and 4 because they have a higher priority (1) than auto_ids 6 and 7 (priority 2).
How can I take priority into account and still remove duplicates in this scenario?

While looking forward to design a multi-columnar cross-tab query I am anxious to know if there could be a way to change the default names of the pivot columns? In other words for the query like the following can there be a way to apply anAS type command to reflect some other names, instead of having the four dates in heading? Something like Month_A, Month_B?
SELECT * FROM
(SELECT
X.REP_DT,
X.CUST_ID
AMOUNT_1
FROM
X) P
PIVOT (SUM(AMOUNT_1) FOR REP_DT IN ([2014-12-31], [2015-01-31], [2015-02-28], [2015-03-31])) PVT_01

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.)

I have a table #vert where I have value column. This data needs to be updated into two channel columns in #hori table based on channel number in #vert table.
CREATE TABLE #Vert (FILTER VARCHAR(3), CHANNEL TINYINT, VALUE TINYINT)
INSERT #Vert Values('ABC', 1, 22),('ABC', 2, 32),('BBC', 1, 12),('BBC', 2, 23),('CAB', 1, 33),('CAB', 2, 44) -- COMBINATION OF FILTER AND CHANNEL IS UNIQUE
CREATE TABLE #Hori (FILTER VARCHAR(3), CHANNEL1 TINYINT, CHANNEL2 TINYINT)
INSERT #Hori Values ('ABC', NULL, NULL),('BBC', NULL, NULL),('CAB', NULL, NULL) -- FILTER IS UNIQUE IN #HORI TABLE
One way to achieve this is to write two update statements. After update, the output you see is my desired output
UPDATE H
SET CHANNEL1= VALUE
FROM #Hori H JOIN #Vert V ON V.FILTER=H.FILTER
WHERE V.CHANNEL=1 -- updates only channel1
UPDATE H
SET CHANNEL2= VALUE
FROM #Hori H JOIN #Vert V ON V.FILTER=H.FILTER
WHERE V.CHANNEL=2 -- updates only channel2
SELECT * FROM #Hori -- this is desired output
my channels number grows in #vert table like 1,2,3,4...and so Channel3, Channel4....so on in #hori table. So I cannot keep writing too many update statements. One other way is to pivot #vert table and do single update into #hori table.

I would like to provide the names of columns in an insert statement from a schema table, so that when running through a number of Bus Rule checks I can reference the schema table and only maintain the columns in the schema table rather than maintain named columns in multiple insert statements. So my query for one check looks like below. I'm using dynamic sql to execute the insert statement. My question is, is there a better way or different way to do this without using dynamic sql? Ie, Is there a way that I can use the columns parameter like this instead?
Insert
('+@columns+',KickoutID) Values('+@columns+',1);
Dynamic code:
Declare @columns as nvarchar(max);
Declare @InvSQL as nvarchar(max);
SELECT @columns =
STUFF ((
SELECT ', [' + name + ']'
FROM syscolumns WHERE id = OBJECT_ID('dbo.table_pvt')
[Code] ....

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

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 !

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;

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.
