Alternative To Creating View With Union In Two Databases?
Jul 20, 2005
I attempted to create a view in SQL Server 2000 that Unions two
queries. The first part of the query gets data from the local server,
the second part gets info from a linked server. (The query works fine
in Query Analyzer.)
I received this error when I tried to save the query:
ODBC error: [Microsoft][ODBC SQL Server Driver] The operation could
not be performed because the OLE DB provider 'SQLOLEDB' was unable to
begin a distributed transaction.
[Microsft][ODBC SQL Server Driver][SQL Server][OLE/DB provider
returned message: New transaction cannot enlist in the specified
transaction coordinator.]
After a little reading I discovered the "Database limitation":
"A view can be created on a table only in the database the view
creator is accessing".
That's my problem... is there a simple solution or alternative to
creating a view?
Thanks,
Matt

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

I've got a view that creates a parent child relationship, this view isused in Analysis Services to create a dimension in a datastore. Thisquery tends to deadlock after about 10 days of running smoothly. Onlyway to fix it is to reboot the box, I can recycle the services for aquick fix but that usually only works for the next 1-2 times I call theview.This view is used to create a breakdown of the bill-to locations fromContinent-Global Region-Country-Sub Region-State/Province- City-ZipCodeYes, I know that sounds crazy, but it was a requirement.So why would I get a deadlock on a SELECT Query? Is there a way to setthe Isolation level to Repeatable Read for a view?Here is the view code:CREATE View dbo.vwBillToas-- US ZipCodeSelect 'Parent'=z.City+' ('+ ISNULL(RTRIM(z.State_shrt), '0') +cast(IsNull(z.US_Region_wk,0) as varchar) + ')',z.Zipcode_WK as 'Child',z.ZipCode_WK as 'Child_ID'Fromdbo.DIM_POSTAL_CODES_US zinnerjoin dbo.FACT_SALES fonz.ZipCode_WK=f.Bill_ToWherez.US_Region_wk IS NOT NULLGroupby z.City,z.ZipCode_WK,US_Region_wk, z.State_shrtUnion--CitySelect 'Parent'=z.State_Long+' ('+cast(IsNull(z.US_Region_wk,0) asvarchar)+')',z.City as 'Child',z.City + ' ('+ ISNULL(RTRIM(z.State_shrt), '0') +cast(IsNull(z.US_Region_wk,0) as varchar) + ')' as 'Child_ID'Fromdbo.DIM_POSTAL_CODES_US zWherez.US_Region_wk IS NOT NULLGroupby z.State_Long,z.City,z.State_shrt,z.US_Region_wkUnion-- Canada ZipCodeSelect 'Parent'=z.City+ ' ('+ ISNULL(RTRIM(z.province_shrt), '0') +')',z.Zipcode_WK as 'Child',z.Zipcode_WK as 'Child_ID'Fromdbo.DIM_POSTAL_CODES_CAN zinnerjoin dbo.FACT_SALES fonz.ZipCode_WK=f.Bill_ToGroupby z.Province_Long,z.ZipCode_WK, z.City, z.province_shrtUnion--CitySelect 'Parent'=z.Province_Long,z.City as 'Child',z.City+ ' ('+ ISNULL(RTRIM(z.province_shrt), '0') + ')' as'Child_ID'Fromdbo.DIM_POSTAL_CODES_CAN zinnerjoin dbo.FACT_SALES fonz.ZipCode_WK=f.Bill_ToGroupby z.Province_Long,z.ZipCode_WK, z.City, z.province_shrtUnion-- Canada ProvinceSelect 'CANADA',Province_Long,Province_LongFromdbo.DIM_POSTAL_CODES_CANGroupby Province_LongUnion-- CountrySelect t.Region_NK,c.Country_Name,c.Country_NameFromdbo.DIM_COUNTRY cInnerJoin dbo.DIM_WORLD_REGION tOnc.Region_WK=t.Region_WKWherec.Country_Name Is Not NullGroup by t.Region_NK, c.Country_NameUnion-- SubRegionSelect c.Country_Name,sr.US_Region_Name,sr.US_Region_NameFromdbo.DIM_US_REGION srInnerJoin dbo.DIM_COUNTRY cOnsr.Country_wk=c.Country_WKGroupby c.Country_Name, sr.US_Region_NameUnion--RegionSelect sr.US_Region_Name,c.State_Long,c.State_Long+' ('+cast(c.US_Region_wk as varchar)+')'Fromdbo.DIM_US_REGION srInnerJoin dbo.DIM_POSTAL_CODES_US cOnsr.US_Region_WK=c.US_Region_WKGroupby sr.US_Region_Name, c.State_Long,c.US_Region_wkUnion-- ContinentSelect Null,Region_NK,Region_NK[color=blue]>From dbo.DIM_WORLD_REGION[/color]WhereRegion_NK Is Not Null

I am looking to create a constraint on a table that allows multiplenulls but all non-nulls must be unique.I found the following scripthttp://www.windowsitpro.com/Files/0.../Listing_01.txtthat works fine, but the following lineCREATE UNIQUE CLUSTERED INDEX idx1 ON v_multinulls(a)appears to use indexed views. I have run this on a version of SQLStandard edition and this line works fine. I was of the understandingthat you could only create indexed views on SQL Enterprise Edition?

Hi guys 'n gals,
I created a query, which makes use of a temp table, and I need the results to be displayed in a View. Unfortunately, Views do not support temp tables, as far as I know, so I put my code in a stored procedure, with the hope I could call it from a View....
I tried:
CREATE VIEW [qryMyView]
AS
EXEC pr_MyProc
and unfortunately, it does not let this run.
Anybody able to help me out please?
Cheers!

We had a divestiture within our company. Now what used to be contained in one database in now split into two databases. One showing all history and one being all current data as of 6/1/2008. Is there an easy way to Union or Join these? Right now I'm currently doing a simple UNION ALL, but can't group the two select statements:
SELECT
Year,Location,QtySold
FROM
historydb
UNION ALL
SELECT
Year,Location,QtySold
FROM
currentdb
Can't do a subset and group both of these selects. How would some of you pro's do this? Right now I can put this in a simple view and then create a SP off of this view that would do this grouping, but it seems like I should be able to do it all in one query. Thanks.

I am having an issue when trying to union all between two databases.
This is the error:
Implicit conversion of varchar value to varchar cannot be performed because the collation of the value is unresolved due to a collation conflict.
I have updated the collation in both DB to Latin1_General_CI_AS and I am still getting the error when running the query.
The queries run separately ok. why I am still getting the collation error.

What is the standard way to union tables with exactly the same schema that are in different databases?
For example:
Code Block
USE db1 SELECT * FROM table1
UNION
USE db2 SELECT * FROM table2
this will return the following error:
Msg 156, Level 15, State 1, Line 3
Incorrect syntax near the keyword 'use'.

Hi,
I have a view V1 created as a plain UNION from 2 tables:
SELECT * FROM T1
UNION
SELECT * FROM T2
If I create another view V2 just filtering V1 through a WHERE clause (e.g. SELECT * FROM V1 WHERE x < y) I don't get any rows returned.
However, if I write the SELECT clause within each branch of the former UNION, I correctly get all the rows.
Is this a known bug of SQL Server 2000? If yes, is there a SP fixing it?
thx,

I have a view that is using UNION ALL to combine common fields of two tables, this is my statement:
SELECT ID, STATUS, ACTIVE_STATUS, NS_PARENT_CHANGE_NUM, NS_REP, NS_CHANGE_NUM, NS_CHANGE_IDENTIFER
FROM dbo.CT_FRAME_T
UNION ALL
SELECT ID, STATUS, ACTIVE_STATUS, NS_PARENT_CHANGE_NUM, NS_REP, NS_CHANGE_NUM, NS_CHANGE_IDENTIFER
FROM dbo.CT_ATM_T
This works fine, but I would also like some fields that do not match to appear in the view. It is OK if the value is null for the rows of data from the other table that doesn't have the columns.
The other columns are called DLCI from CT_FRAME_T and then VPI, VCI from CT_ATM_T.
My view would then return ID, STATUS, ACTIVE_STATUS, NS_PARENT_CHANGE_NUM, NS_REP, NS_CHANGE_NUM, NS_CHANGE_IDENTIFER, DLCI (where applicable), VPI and VCI (where applicable). Is this possible?

HI, Guys:
I've some AT_DATE tables (eg: AT_20080401, AT_20080402, ...) in SQLServer DB, and these AT_XX table have same columns. but table count could be variant, so I have to query sysobjects to get all of these tables. like this:
select name from sysobject where name like 'AT_%'
Now I try to create a view AT which is the union of all these AT_XX tables, such as:
Code Snippet
Create View AT as
select * from AT_20080401
union
select * from AT_20080402
union ...
but since I'm not sure how many tables there, it would be impossible to write SQL as above.
though I could get this union result via stored-procedure, view couldn't be created on the resultset of a procedure.
Create View AT as
select * from AT_createView() <-- AT_createView must be a function, not procedure
I've checked msdn, there is Multi-statement table-valued function, but this function type seems to create one temporary table, I don't want to involve much of insert operation because there could be more than 1million records totally in these AT_XX tables.
So is there any way to achived my goal?
any reference would be appreciated, thanks !

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

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 want to create a raw SQL resultset for outputting to Excel with some artificial headers transposed over the top of the 2nd part of the Union's column names. The first part of the Union will be the Headers. Like this, the space to the left of the topmost columns is preferably empty ....
COL 1 COL2 COL3 COL4 etc. BEH BIG BPL etc.
************************************* INTAKT DEFEKT INTAKT DEFEKT INTAKT
************************************* B E B E B
I just want the text above as a 3 line header and there won't be any values obviously. Then the 2nd query will be joined to the above with a Union all. The 2nd query has all the same column names as what will be given in the first set above. What is the SQL Syntax for doing so? Do I have to use a from clause?

I installed the desktop version so it is running but now how do I create and edit databases and tables and so forth. Help is greatly apprieciated as the only other sql I have done is for php forums.

Hi,
I'm using SQL Server 2005 Express for an application.
SQL Server 2005 Express supports 4GB user data per database. Because need over 4GB(may be 20GB ~ 30GB) data space, I should split database which each max size up to 200 MB. And create 100 databases.
Is it reasonable? If true, what about the performance or system's overhead?
Thank you.

I have a reporting server with 5 databases which are currently being updated via log shipping. These databases need to be (read) accessed by the users. All users have System Admin perms due in order to access the databases. I need to tighten security on the server and remove SA perms from the users. The largest database is about 8gb and is growing slowly. What is the best way to move the databases efficiently from the source server to the reporting server? The log shipped databases can't be backed up and restored due to the standby mode. DTS is an option but may pose time issues due to database size especially as the databases grow in the future. Replication is another option but i have heard it has alot of issues. Any help is welcome. Thanks.

We have created a view that selects from tables in two databases. it looks like something like this:
CREATE VIEW myview AS
SELECT col FROM db1.mytab
UNION SELECT col FROM db2.mytab;
Both tables have col as primary key.
When we executes SELECT col FROM myview WHERE col='SOMEVALUE' we receives the correct result but SQL server does not use any indexes. It performs a index scan on both tables. Wh and what can we do about it? The tables contains millions of rows so the performance is terrible.
The following works fine:
SELECT col FROM db1.mytab WHERE col ='SOMEVALUE'
UNION SELECT col FROM db2.mytab WHERE col ='SOMEVALUE';
Qe are running SQL Server 2000 and TRANSACT SQL
