SQL Server 2014 :: UNION ALL In View With Temp Table

May 8, 2015

I have a performance issue with one of the views when I join the view with a temp table

I have 2 Views - View1 and View2.

There is a third view - view_UNION where the

view_UNION =
SELECT * FROM View1
UNION ALL
SELECT * FROM View2

If I have a query like -

Select view_UNION.* FROM
view_UNION INNER JOIN #TMP ON #TMP.ID = view_UNION.ID

the execution is too slow.

But if I execute the views separately, I get good performance.

How to improve the performance of the view_Union

SQL Server 2014 :: UNION Vs PIVOT For De-flattening SOME Columns Of A Partially Flat Table

Jan 23, 2015

We have a table with 500+ columns. The data is non-normalized, i.e. there are four groups of fields for for "people", followed by data that applies to all people in the row (a "household").For ad-hoc queries, and because I wanted to index columns within each person (person 1's age, person 2's age, etc.), I used UNION:

SELECT P1Firstname AS FirstName, P1LastName as LastName, P1birthday AS birthday, HouseholdIncome, HouseholdNumber of Children, <other "household" columns>
UNION
SELECT P2Firstname AS FirstName, P2LastName as LastName, P2birthday AS birthday, HouseholdIncome, HouseholdNumber of Children, <other "household" columns>

I could get at least the P1... P2... P3... columns with PIVOT, but then I believe I'd have to JOIN back to the row anyway for the "household" columns. Performance of UNION good, but another person here chose to use PIVOT instead.I can' find any articles on PIVOT vs. UNION for "de-flattening".

Results Of Union Into Temp Table

Apr 3, 2008

This may be a dumb question, but I can't seem to get the syntax right. I have two temp tables that have the same columns, I want to do a union on them and store the results in a temp table. Any ideas?

Ie.

select * from #tmpTable1
union
select * from #tmpTable2
into #tmpTable3

Thanks!!!

Temp Table Vs. Union: Which Has Better Performance?

Aug 13, 2007

Right now, a client of mine has a T-SQL statement that does thefollowing:1) Create a temp table.2) Populate temp table with data from one table using an INSERTstatement.3) Populate temp table with data from another table using an INSERTstatement.4) SELECT from temp table.Would it be more efficient to simply SELECT from table1 then UNIONtable 2? The simply wants to see the result set and does not need tore-SELECT from the temp table.

SQL Server 2014 :: Loop And Query CSV Files In Folder Using Union All Query To Form Resultant Table On Server?

Jun 27, 2014

I am trying to run a UNION ALL query in SQL SERVER 2014 on multiple large CSV files - the result of which i want to get into a table in SQL Server. below is the query which works in MSAccess but not on SQL Server 2014:

SELECT * INTO tbl_ALLCOMBINED FROM OPENROWSET
(
'Microsoft.JET.OLEDB.4.0' , 'Text;Database=D:DownloadsCSV;HDR=YES',
'SELECT t.*, (substring(t.[week],3,4))*1 as iYEAR,
''SPAIN'' as [sCOUNTRY], ''EURO'' as [sCHAR],

[Code] ....

What i need is:

1] to create the resultant tbl_ALLCOMBINED table

2] transform this table using PIVOT command with following transformation as shown below:

PAGEFIELD: set on Level = 'Item'
COLUMNFIELD: Sale_Week (showing 1 to 52 numbers for columns)
ROWFIELD: sCOUNTRY, sCHAR, CATEGORY, MANUFACTURER, BRAND, DESCRIPTION, EAN (in this order)
DATAFIELD: 'Sale Value with Innovation'

3] Can the transformed form show columnfields >255 columns i.e. if i want to show all KPI values in datafield?

P.S: the CSV's contain the same number of columns and datatype but the columns are >100, so i dont think it will be feasible to use a stored proc to create a table specifying that number of columns.

SQL Server 2014 :: Trigger On A View If Any Insert / Update Occurs On Base Table Level

Apr 21, 2015

I have a situation where I have Table A, Table B.

View C is created by joining table A and table B.

I have written a instead of trigger D on view C.

I do not insert/update/delete on the view directly.

For every insert/update in table A /B the values should get insert/update in the view respectively. This insert/update on view should invoke the trigger.

And I am unable to see this trigger work on the view if any insert/update occurs on base table level.

Trigger is working only if any operation is done directly on the view.

View On The Fly Or Temp Table

May 6, 2008

problem:

Have a table with Data and Dependencies(Foreign Keys) and Stored Procedures, views etc.
Need the Data in that table to put in different order.
For exampl, put older years in the begining or end so when sorted by year, you will get right data.
Question is: If i use view it will be based on the table with Wrong entry order and if i use Temporary Table
each time stored procedure is run, it will be created and overhead.

Example of the table is below with Wrong order.
I should have entered the old years first.
Note this is example and not the actual table!


ID Yr Title/Model Serial#

---------------------------------
1 2005 Toyota Camery IXp12365555
2 2006 Honda Accord XJi9770009
3 2007 Honda Accord XJi9000009
4 2004 Honda Accord XJi9880009
5 2005 Honda Accord XJi9009009
6 2007 Honda Accord XJi9078009

If this example is not right, my bottom line is this:
I have entered the Data in a table and i'm getting wrong resutls when i order by Desc or Asc and now either have to delete all rows and re-enter it or have someother clever way!

Avoid Table Scan Using Multi Union View

May 26, 2008

Anyone see a way to trick the optimizer into not scanning all tables involved in the view?


-- create two test tables
create table dbo.test1
(testID int, TestName varchar(10))

create table dbo.test2
(testID int, TestName varchar(10))

-- populate
declare @i int
set @i = 1000
while @i > 0
begin
insert into dbo.test1
select @i, '1.' + cast(@i as varchar(5))
set @i = @i - 1
end

insert into dbo.test2
select 1, '2.1' union all
select 2, '2.2'
go

-- create view
create view dbo.vw_Test
as
select1 as QueryID,
TestName
fromdbo.Test1
union all
select2 as QueryID,
TestName
fromdbo.Test2;
go


-- this works as i want, only scans table dbo.Test2
select *
fromdbo.vw_Test
whereQueryId = 2

-- joining to a table triggers scan of both tables in view:
declare @table table (QueryID int)
insert into @table
select 2;

selectvt.TestName
fromdbo.vw_Test vt
join@table t on
vt.QueryID = t.QueryID



Using the showplan I can see why the optimizer ends up scanning all tables, but maybe there is a way to force it to use the QueryID param evaluation earlier in the filtering.

I think then there would be an easy way to get around this problem.

This is the code:

SQL Server 2014 :: Union All Statement Hangs Engine?

Sep 9, 2014

I have TSQL query using UNION ALL. First subset returns 92 rows, second subset return 0 (ZERO) rows. Now if I execute them separately they execute subsecond. If I put UNION ALL between them then it hangs forever exactly on 88s row.

I understand I need to provide execution plans, actual queries etc but before going into all this details, why on earth even in theory UNION ALL with empty result will result in a hang of the first subset?

Based on estimated execution plan 2 subqueries are performed in parallel and then CONCATENTION is being used which shall result with just first subset immediately displayed in result.

Estimated execution plan attached, I can not get actual execution plan because query never completes.

Using Union All When Inerting Into Temp Tables

Oct 4, 2007

Hello,
I'm using SQL2005, SP2

I have multiple temp tables with the same column structure that I would combine into into a single temp table using Unions.
Is this possible?

Example:
Select * From #temp1
Union All
Select * From #temp2
Union All
Select * From #temp3

Into #Temp4


I thought I would ask while I continue to research this in case someone came back with the solution before I was able to track it down elsewhere.


Thanks!

Trouble With Temp Tables And UNION Keyword

Feb 18, 2008

I'm trying to summarize costs assigned to active jobs for a manufacturing business. I need to aggregate work in process (WIP) cost that resides in labor-transaction and part-transaction tables based on transaction types, and transaction dates. Some transactions increase the WIP cost of the job while others decrease WIP. The business needs to see how much $$ is tied up in each job as of a particular date -- the calculation is:
ToDate (cost of materials and labor assigned to job)
- ToInv (cost of materials returned to inventory)
- ToSales (cost of materials sold).

I developed this query incrementally and, so far, the #ToDate, #ToInv, and #ToSales temp tables seem to be populating with the correct data. My thought was to combine these three tables with a UNION and then extract the grand totals and here's where I started getting the following error:
------------------------------------------
Incorrect syntax near the keyword 'UNION'.
------------------------------------------
The problem is with the UNIONs going into #myTotal.

I would appreciate any help with this. Also, please let me know if you can suggest a better design for this. Thanks!

Below is a simplified version of my query:

--#ToDate
CREATE TABLE #ToDate (JobNum varchar(14), Cost decimal (16,2)
INSERT INTO #ToDate (JobNum, Cost)

--M&S To Date
SELECT pt.jobnum,
SUM(pt.extcost) AS Cost
FROM parttran pt
JOIN jobhead jh ON pt.jobnum=jh.jobnum
WHERE trantype IN ( <valid trans types> )
AND jh.JobReleased = 1
AND pt.TranDate < '2007-9-30'
GROUP BY pt.jobnum

UNION -- This one works ok.

--L&B To Date
SELECT jh.JobNum,
sum(l.LaborRate*l.LaborHrs) + sum(l.BurdenRate*l.BurdenHrs) AS Cost
FROM LaborDtl l
JOIN JobHead jh ON l.JobNum = jh.JobNum
WHERE jh.JobReleased = 1
AND l.PayrollDate < '2007-9-30'
GROUP BY jh.JobNum

--#ToInv
CREATE TABLE #ToInv (JobNum varchar(14), Cost decimal (16,2)
INSERT INTO #ToInv (JobNum, Cost)

SELECT pt.jobnum,
SUM(pt.extcost) AS ToInv
FROM parttran pt
JOIN jobhead jh ON pt.jobnum=jh.jobnum
WHERE trantype IN (<valid trans types>)
AND jh.JobReleased = 1
AND pt.TranDate < '2007-9-30'
GROUP BY pt.jobnum

--#ToSales
CREATE TABLE #ToSales (JobNum varchar(14), Cost decimal (16,2))
INSERT INTO #ToSales (JobNum, Cost)

SELECT pt.jobnum,
SUM(pt.extcost) AS ToInv
FROM parttran pt
JOIN jobhead jh ON pt.jobnum=jh.jobnum
WHERE trantype IN (<valid trans types>)
AND jh.JobReleased = 1
AND pt.TranDate < '2007-9-30'
GROUP BY pt.jobnum

--#myTotal
CREATE TABLE #myTotal (JobNum varchar(14), Cost decimal (16,2), Source varchar(9))
INSERT INTO #myTotal (JobNum, Cost, Source)

SELECT d.JobNum, SUM(d.Cost) AS Cost FROM #ToDate d GROUP BY d.JobNum ORDER BY d.JobNum

UNION -- Problem**********************

SELECT i.JobNum, SUM(-1*i.Cost) AS Cost FROM #ToInv i GROUP BY i.JobNum ORDER BY i.JobNum

UNION -- Problem**********************

SELECT s.JobNum, SUM(-1*s.Cost) AS Cost FROM #ToSales s GROUP BY s.JobNum ORDER BY s.JobNum


--Select grand total for each job
SELECT JobNum, SUM(Cost) FROM #myTotal ORDER BY JobNum

--Drop temp tables
DROP TABLE #ToDate
DROP TABLE #ToInv

SQL Server Admin 2014 :: Selected Columns On View

Mar 18, 2015

I have created row level security on two views and adding these two views to particular role.Today I have got an requirement that, middle level managers shouldn't see the all the columns. So I have created another role for Middle level managers and assign securables as those two views with selected columns by grant, and map all the middle level managers to this role. I thought my job is done. But these managers uses this view on SSAS(tabular model) and Excel, In those applications they are not able to load the data.

Later I come to know we can't use -- select * from ViewA ( in viewA I have restristced few columns in the role level) Work around is creating another view and assigning to the role. But how can we achieve column level security to implement this in either SSAS/SSRS/EXCEL?

SQL Server 2014 :: Indexed View Not Being Used For Partitioned Clustered Column-store Index?

Oct 9, 2015

I am trying to use an indexed view to allow for aggregations to be generated more quickly in my test data warehouse. The Fact Table I am creating the indexed view on is a partitioned clustered columnstore index.

I have created a view with the following code:

ALTER view dbo.FactView
with schemabinding
as
select local_date_key, meter_key, unit_key, read_type_key, sum(isnull(read_value,0)) as [s_read_value], sum(isnull(cost,0)) as [s_cost]
, sum(isnull(easy_target_value,0)) as [s_easy_target_value], sum(isnull(hard_target_value,0)) as [s_hard_target_value]
, sum(isnull(read_value,0)) as [a_read_value], sum(isnull(temperature,0)) as [a_temp], sum(isnull(co2,0)) as [s_co2]
, sum(isnull(easy_target_co2,0)) as [s_easy_target_co2]
, sum(isnull(hard_target_co2,0)) as [s_hard_target_co2], sum(isnull(temp1,0)) as [a_temp1], sum(isnull(temp2,0)) as [a_temp2]
, sum(isnull(volume,0)) as [s_volume], count_big(*) as [freq]
from dbo.FactConsumptionPart
group by local_date_key, read_type_key, meter_key, unit_key

I then created an index on the view as follows:

create unique clustered index IDX_FV on factview (local_date_key, read_type_key, meter_key, unit_key)

I then followed this up by running some large calculations that required use of the aggregation functionality on the main fact table, grouping by the clustered index columns and only returning averages and sums that are available in the view, but it still uses the underlying table to perform the aggregations, rather than the view I have created. Running an equivalent query on the view, then it takes 75% less time to query the indexed view directly, to using the fact table. I think the expected behaviour was that in SQL Server Enterprise or Developer edition (I am using developer edition), then the fact table should have used the indexed view. what I might be missing, for the query not to be using the indexed view?

Creating A View Using A Union?

Jan 14, 2015

I am looking to create a new view by combining two tables, but i would like to create a new column in the view that identifies what table the data came from. For example I have a Table A and Table B, using a union i combined the two table but i want a new column titled Source which could be populated by A or B.

This is my code so far:

Create View Table_AB As
Select *From Table_A
Union All
Select*From Table_B
