Temp Table On Linked Server
Oct 7, 2005
Trying to do this all day and googling for answers but found none, hope
someone can help. Thanks in advance.
select * into
OPENROWSET('SQLOLEDB','SERVER';'uid';'pwd',##test)
from LocalTable
Reason: I am joining local tables with linked server tables using the
format "LinkedServer.database.owner.object" to execute a query, it
takes forever to execute since the tables joined on the remote servers
have more than 50Mil records. I read somewhere that sql server needs to
copy the tables locally to the temp db and does the join there, hence I
was hoping to dump the data of the local database into a temp table on
the remote server and then do a join with OPENQUERY, which will execute
the query on the linked server and return the results.

Hello
I have a local SQL2005 server with a linked SQL2000 server. I would like to know how to create a temporary table in the remote server in such a way that I can make an inner join as follows; my idea is to optimized a distributed query by doing so:
create table #myRemoteTempTable
insert into #myRemoteTempTable
select * from myLocalTable
update myRemoteTable
set
Value=#myRemoteTempTable.Value
from myRemoteTable
inner join #myRemoteTempTable on #myRemoteTempTable.ID=myRemoteTable.ID

Hi,
I would like to join two tables: one on a local server which I have admin access to and another server which I only have read access. The local table is very small, but the remote table is very large.
If I look at Query Analyzer's execution plan, it appears that the join will be done locally (i.e. the entire table is transferred from the remote server and then joined to my local table). Is there a way to create a temp table using linked servers, transfer my small local table to the remote server and then perform the join on the remote server? In the past, I have been able to use openquery to restrict the data to a small subset that is transferred but the local table is a little too large for that.
I appreciate any advice / guidance anyone can offer me!

Below are my temp tables
--DROP TABLE #Base_Resource, #Resource, #Resource_Trans;
SELECT data.*
INTO #Base_Resource
FROM (
SELECT '11A','Samsung' UNION ALL
[Code] ....
I want to loop through the data from #Base_Resource and do the follwing logic.
1. get the Resourcekey from #Base_Resource and insert into #Resource table
2. Get the SCOPE_IDENTITY(),value and insert into to
#Resource_Trans table's column(StringId,value)
I am able to do this using while loop. Is there any way to avoid the while loop to make this work?

i am inserting something into the temp table even without creating it before. But this does not give any compilation error. Only when I want to execute the stored procedure I get the error message that there is an invalid temp table. Should this not result in a compilation error rather during the execution time.?
--create the procedure and insert into the temp table without creating it.
--no compilation error.
CREATE PROC testTemp
AS
BEGIN
INSERT INTO #tmp(dt)
SELECT GETDATE()
END
only on calling the proc does this give an execution error

I am using SQL Server 2005 and trying to create a linked server on Oracle 10. I used the commands below:
EXEC sp_addlinkedserver
@server = 'test1',
@srvproduct = 'Oracle',
@provider = 'MSDAORA',
@datasrc = 'testsource'
exec sp_addlinkedsrvlogin
@rmtsrvname = 'test1',
@useself = 'false',
@rmtuser='sp',
@rmtpassword='sp'
When I execute
select * from test1...COUNTRY
I get the error. "The OLE DB provider "MSDAORA" for linked server "...." does not contain the table "COUNTRY". The table either does not exist or the current user does not have permissions on that table."
The 'sp' user I am connecting is the owner of the table. What could be the problem ?
Thanks a lot.

Hi I have the following Stored Proc which works in SQL Server 6.5 but not in SQL Server 7.0. All this Stored Proc does is Create a temp table, execute the DBCC ShowContig on a table and insert the results of the DBCC into a temp table. What am I missing. Thanks.
The code of the Stored Proc is:
/* This Stored Procedure Creates a temp table. (Step 1) */
/* Initializes a local variable @StirngToBeExecuted with */
/* a DBCC command. (Step 2) */
/* Step 3. The Command is Executed and the results of the */
/* DBCC command is inserted into Temp Table. */
/* Step 4. The results of the Temp table are shown on the */
/* Screen. */
/* This SQL Works Fine in SQL Server Version 6.5 */
/* In SQL Server 7.0 the results of the DBCC command is */
/* NOT getting inserted into the Temp table. WHY??? */
IF EXISTS (SELECT * from sysobjects where id = object_id('dbo.Test_sp') and sysstat & 0xf = 4)
drop procedure dbo.Test_sp
GO
CREATE PROCEDURE Test_sp
AS
DECLARE
@StirngToBeExecuted Varchar(100)
CREATE TABLE #temp( -- Step 1
OutputOfExecute Varchar(255)
)
-- Step 2
SELECT @StirngToBeExecuted = 'DBCC SHOWCONTIG (123456789)'
INSERT
INTO #temp exec (@StirngToBeExecuted) -- Step 3
SELECT * FROM #temp -- Step 4
DROP TABLE #temp --Drop the Temp Table

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

I think this is a very simple question, however, I don't know the
answer. What is the difference between a regular Temp table
and a Global Temp table? I need to create a temp table within
an sp that all users will use. I want the table recreated each
time someone accesses the sp, though, because some of the
same info may need to be inserted and I don't want any PK errors.
thanks!!

Strange one here - I am posting this in both SQL Server and Access forums
Access is telling me it can't append any of the records due to a key violation.
The query:
INSERT INTO dbo_Colors ( NameColorID, Application, Red, Green, Blue )
SELECT Colors_Access.NameColorID, Colors_Access.Application, Colors_Access.Red, Colors_Access.Green, Colors_Access.Blue
FROM Colors_Access;
Colors_Access is linked from another MDB and dbo_Colors is linked from SQL Server 2000.
There are no indexes or foreign contraints on the SQL table. I have no relationships on the dbo_ table in my MDB. The query works if I append to another Access table. The datatypes all match between the two tables though the dbo_ tables has two additional fields not refrenced in the query.
I can manually append the records using cut and paste with no problems.
I have tried re-linking the tables.
Any ideas?
Thanks,
Brad

In a stored procedure I dynamically create a temp table by selecting the name of Applications from a regular table. Then I add a date column and add the last 12 months. See attachment.
So far so good. Now I want to update the data in columns by querying another regular table. Normally it would be something like:
UPDATE ##TempTable
SET [columName] = (SELECT SUM(columName)
FROM RegularTable
WHERE FORMAT(RegularTable.Date,'MM/yyyy') = FORMAT(##TempMonths.x,'MM/yyyy'))
However, since I don't know what the name of the columns are at any given time, I need to do this dynamically.
how can I get the column names of a Temp table dynamically while doing an Update?

I could deploy across my environment, which is a mix of 2008R2/2012 servers, to give some information on log files. Running into a silly issue right off the bat. The table that DBCC LogInfo() conjures out of magic is different between the two. In 2012 it gained the RecoveryUnitID column. So I'm trying to write some logic to create a temp table based on which version is running. I would like to avoid a global temp table if possible. Here's what I've tried:
sp_executesql creates a table outside of the scope of my session:
DECLARE @PrVers NVARCHAR(128)
, @PrVersNum DECIMAL(10,2)
, @StageTable NVARCHAR(1024) = N''

I have a dynamic sql which uses Pivot and returns "technically" variable no. of columns.
Is there a way to store the dynamic sql's output in to a temp table? I don't want to create a temp table with the structure of the output and limit no. of columns hence changing the SP every time I get new Pivot column!!

what are some common techniques for ensuring an isolated temp table scope? For example, if 2 different sprocs happen to crud a temp table with the same name? I'm guessing that big SQL shops establish a standard for this early on to avoid conflicts between sprocs.

SQL Server 7.0 (SP1)
Error:
------
OLE DB provider 'SQLOLEDB' supplied inconsistent metadata. An extra column was supplied during execution that was not found at compile time.
A column was deleted from the a table on the linked server and now this message appears when using the linked server definition to access the table. Deleting/Recreating the Linked Server has no effect. I found an earlier note on this...but it just kind of ended with no resolution. Anyone have any thoughts on this now.
Thanks for any input.

Using a string of IDs passed into a stored procedure as a VARCHAR parameter ('1,2,100,1020,') in an IN without parsing the list to a temp table or table variable. Here's the situation, I've got a stored procedure that is called all the time. It's working with some larger tables (100+ Million rows). The procedure passes in as one of the variables a list of IDs for the large table. This list can have anywhere from 1 to ~100 IDs passed to it.
Currently, we are using a function to parse the list of IDs into a temp table then joining the temp table to get the query:
CREATE PROCEDURE [dbo].[GetStuff] (
@IdList varchar(max)
)
AS
SET NOCOUNT ON
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
[Code] .....
The problem we're running into is that since this proc gets called so often, we sometimes run into tempDB contention that slows this down. In my testing (unfortunately I don't have a good way of generating a production load) swapping the #table for an @table didn't make any difference which makes sense to me given that they are both allocated in the tempDB. One approach that I tried was that since the SELECT query is pretty simple, I moved it to dynamic SQL:
CREATE PROCEDURE [dbo].[GetStuff] (
@IdList varchar(max)
)
AS
SET NOCOUNT ON
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
[Code] ....
The problem I had there, is that it creates an Ad Hoc plan for the query and only reuses it if the same list of parameters are passed in, so I get a higher CPU cost because it compiles a plan and it also causes the plan cache to bloat since the parameter list is almost always different. Is there an approach that I haven't considered that may get the best of both worlds, avoiding or minimizing tempDB contention but also not having to compile a new plan every time the proc is run?

Using Microsoft SQL 2000
When creating a table I want to be able to specify not only the db to create it on but also which server to create it on. I have two servers that are linked together, I can view all data without issue.
Doing further research it looks like with the create table command you can tell it the new table name and the database but you can't tell it which server to use. Is there a way of doing this?
Example :
CREATE TABLE LAPTOP.database.dbo.tableName (a INT) gives the following error:
The object name 'LAPTOP.database.dbo.' contains more than the maximum number of prefixes. The maximum is 2.
I am new to linked servers so basically my question is, how do you point to a server within sql before I execute the create table command?
Tx in advance

Hi,
We're having a few linked servers in our company. some tables in one of the linked servers include columns (better saying, foreign keys) of tables in another server. I wonder if there's a way to create a foreign key referencing one column in another server. That is, suppose there's Column A in table A in Server A which references Column B in table B in server B, is there a way to create column A as foreign key referencing column B?
Any idea is appreciated.

Insert statement to remote server is running very slowly. I have run Profiler and find there is a 'sp_cursor' call for each row. The source system is SQL2005 and destination is SQL2000(sp4). The linked server is using 'SQL server' type connection. Source query is against a single table with a where clause. source and destination table are identical with Primary keys. Purpose is just to move the rows. Connection is a slow network connection - should be ok. I have already overcome same problem for related update and delete queries by use of 'EXECUTE (query) AT LinkedServer' that works great - but insert can not take advantage of this...
INSERT [LinkedServSQL2000sp4].dbname.schema.tablename
({column list})
Select
{column list}
from tablename
WHERE col1 = '7/20/2006'
AND col2 in (2,5,7,12,32,54,45,33)
Any thoughts?

I wonder if it possible to move data from tables on a linked server to a "normal database"?
Name linked server: Covas
Name table on linked server: tblCountries
Name field: cntCountryName
Name "normal" database: CovasCopy
Name "normal" table: Countries (or dbo.Countries)
Name "normal" field: Country
This is just a test setup. I figure that if I get this working the rest will be easier.
My current query:
select * from openquery(COVAS,'
INSERT INTO CovasCopy.dbo.Countries(Country)
SELECT cntCountryName FROM db_covas.tblCountries;')

Hi,
I'm trying to copy all the data from a single table across to a remote linked server and I'm having all sorts of problems.
The SQL query I'm attampting is this:-
Code:
EXEC sp_addlinkedserver 'GODZILLA', N'SQL Server'
EXEC sp_addlinkedsrvlogin 'GODZILLA', 'False', 'rmtUser', 'lclUser', 'password'
Go
--DELETE TABLE
DROP TABLE GODZILLA.Racing.dbo.horse
--SELECT INTO
SELECT horse_id, horse_filename, horse_time, horse_new, horse_driveLetter
INTO GODZILLA.Racing.dbo.horse
FROM Racing.dbo.horse
EXEC sp_droplinkedsrvlogin 'GODZILLA', 'lclUser'
EXEC sp_dropserver 'GODZILLA'
Basically - this doesn't work as an error is returned:-
Code:
The object name 'GODZILLA.Racing.dbo.' contains more than the maximum number of prefixes. The maximum is 2.
Now - it has no problem running a SELECT (ie read-only) query from the remote DB but why does it have a problem with writing? And if thats the issue, why doesn't it say so. Am I going about this the right way???
Please help!

Hi,
I am trying to use linked tables to connect SQL Server 2000 to a legacy system using dbase III files. (I need real time read only access to these files)
I have created a linked table from SQL server to a folder on the C drive which contains the dbase III files, using an ODBC DSN which uses "Microsoft dbase driver (*.dbf)". DSN tested successfully using Excel. Linked server connection is then created using "Microsoft OLE DB Provider for ODBC drivers".
The dbase tables appear OK in Enterprise manager, but I cannot get a query to work in SQL Anayzer, using the 4-part name syntax.
My query is just :
SELECT * FROM LinkedTable...customers
Error message is "Invalid schema or catalog specified for provider 'MSDASQL'". Now I am pretty sure dbase files do not support any sort of schema / catalog set up, so I suspect SQL Server is looking for something it is not going to get.
One clue might be that in Enterprise manager, under the catalog column, I get the pathname to the dbase file, ie c:customers.dbf, which I cannot enter in the 4-part syntax.
Any suggestion welcome !!!
