I have access to a View called (vw_table) on Server1. I want to get the data
from this view (few million records) into a table on server2.
I tried
SELECT * INTO ##TempTable
FROM VW_Table
This gets the data in to ##TempTable.
Now how can I move it to a different server (server2) and to a different database?
I want Table2 in Server2 to have the data from VW_table.
I appreciate your help.
you cant direct access another server like this.
You have to options to solve your problem:
Configure a linked server on server1 to access server2 then you do: select * from mylinkedserver..table
Create a SSIS package to read data from server1 and insert on server2
Like Lemak said, you can't pass temporary tables around like this. You either need to have a Linked Server and copy the data directly into the table, or you need to export the data and import it into the table using SSIS.

I have a remote database that I want to copy on my local SQL Server.
IMPORTANT: I only want a sample data (1k rows for instance) from each table, and there are about 130 different tables.
I have tried to use the export data procedure in SSMS. Put simply, I go to TASKS> EXPORT DATA > CHOSE SOURCE (the remote db)> CHOSE DESTINATION (my local db) > CHOSE THE TABLES TO COPY > COPY
What I have tried:
I've tried to write down in this tool the SQL query like
SELECT TOP 1000 *
FROM TABLE1 GO ...
SELECT TOP 1000 *
FROM TABLE130
But on the mapping step, it puts every result within a single table instead of creating the 130 different output tables.
FYI, the above procedure is taking 2min for one table. Doing it one by one for each table will take 130 *2min = 4hours and half... plus it is so boring
Do you have any idea for resolving this situation?
Thank you
regards
If you only want a subset you are going to have problems with foreign keys, if there are any in your database.
Possible approaches to extract all data or a subset
Use SSIS to extract the data from the source db and load into your local db
Write a custom application that does the job. (You can use SQL Bulk Copy)
If you purely wan't to do do it in SSMS you can create a linked server on your local server to the remote server.
This way you can do something like this if the tables or not yet created on your local server:
SELECT TOP 1000 *
INSERT INTO [dbo].Table1
FROM [yourLinkedServer].[dbo].[Table1]
Changing the INTO table and FROM table for each table you want to copy.
I want to move the record from one server to another server on certain criteria.
Note
I don't want to move all the records, I will do some filter on records that which I want
I have to move the records on daily basis.
That server is not in local network.
So If I make stored procedure using linq server, it is possible to move the records. But I don't think it is good way. Is there any other way to solve this issue?
UPDATE
what about BCP Utility?.
I don't have such awareness about it, Is it good performance to export and import for bulk data?
Do the following things :
1. Create Linked server
2. writer Query
Let Server1 with IP:172.16.9.13
Server2 with IP:172.16.9.14
You want to move data from Server1 to Server2 then first add Server2 at Server1
The Write Query Like
Insert into 172.16.9.14.SomeTable
select * from 172.16.9.13.SomeTable where isactive=1
====================Create Linked Server =====================

You can add linked server and create procedure for moving records as per your filter criteria.Then schedule sql job on daily basis.
Sample Link for Creating Job
Second option:-
Please create Web service .In that service do this functionality .First fetch the data from target server and then insert to source server.Run this webservice in daily basis using timer or HangFire
I cannot use linked server.
Both databases on both servers have the same structure but different data.
I have 10k rows to transfer from the DB on one server to the same DB on the other. I cannot restore the DB on the other server as it will take a huge amount of space that I don't have on the other server.
So, I have 2 options that I don't know how to execute:
Backup and restoring only one table - the table is linked to many other tables but these other tables exist on the other server too. Can I somehow delete or remove the other tables or make a backup only over one table?
I need to transfer 10k rows. How is it possible to create 10k insert queries based on selected 10k rows?
Can I somehow delete or remove the other tables or make a backup only over one table?
No you can not do this, unfortunately
How is it possible to create 10k insert queries based on selected 10k rows?
Right-click on Database -> Tasks -> Generate scripts -> (Introduction) Next
Chose Select specific database objects -> Tables, chose table you need -> Next
Advanced -> Search for Types of data script change from Schema only (by default) to Data only -> OK
Chose where to save -> Next -> Next. Wait the operation to end.
This will generate the file with 10k inserts.
Another way is to use Import/Export wizard (the most simple way for one-time-import/export) if you have link between databases.
There are many ways to choose from, here is one way using BCP. That's a tool that ships with SQL Server to Import and Export Bulk Data.
The outlines of the process:
Export the data from the source server to a file using BCP - BCP OUT for a whole table, or BCP QUERYOUT with a query to select the 10k rows you want exported
Copy the file to the destination server
Import the data using BCP on the destination database - BCP IN.
My suggestion would be to export these rows to excel( you can do this by copy pasting your query output) and transfer this to other server and import it there.
this is the official method :-
https://learn.microsoft.com/en-us/sql/relational-databases/import-export/import-data-from-excel-to-sql
and this is the the unofficial method :
http://therealdanvega.com/blog/2010/08/04/create-sql-insert-statements-from-a-spreadsheet.
Here I have assumed that you only need to transfer the transactional data and your reference data is same on both server. So you will need to execute only one query for exporting your data
I would definietely go down the SSIS route once you use SSIS to do a task like this you will not use anything else very simple to script up. You can use any version and it will be a simple job and very quick.
Open new SSIS project in available visual studio version/s there are many different but even a 2008 version will do this simple task you may have to install integration services or something similar used to be called bids (business information development studio in 2008) (anything up to 2015 although support is nearly there in 2017)
add a data flow task
double click the data flow task
Bottom of screen add two connection managers (1 to source and 1 to destination database)
add oledb source pointing to source database table
add oledb destination pointing to destination database table
drag line between the source and destination (should auto map all columns if the same name)
hit Start and the data will flow very quickly
you have create DbInstaller. using dbInstaller you have share whole database. Dbinstaller work both ado.Net and Entity Frame Work but I have using Entity Frame Work.
you can do it by sql server query
first select first database like
Use database1 --- this will be your first database
after select first database we will put our table row in temp table by this query
select * into #Temp from select * from table1
now we select second database and insert temp table data into second database table by this code
use secondDatabaseName
INSERT INTO tableNameintoinsert (col1, col2, )
SELECT col1, col2 FROM #temp;
how to fetch the data from one database table on another server and insert in to another database table sitting on a different server....I can't to do this.Is it possible using SQL statement or do I need a tool?
You could create a linked server on the instance that you are importing data into. You will need to link the server that you are exporting data from. Here are a couple of links on how to set that up.
How to Create a Linked Server
StackOverflow Answer
Calling Linked Server In Query
Once you have the linked server set up, you could do this:
INSERT INTO yourtable --table you are importing data into
SELECT *
FROM [server].[database].[schema].[table] --server you are exporting data from
How can I get #tempTable to stay in memory after switching servers. Is this possible?
Select *
into #tempTable
from dbo.table
I have data in server 1 that I want to compare in server 2, but I only have readonly access to server 2 (so I can't just move my data there), and the table in server 2 is too big to move to server 1. This is why I want to know how to keep a temp table in memory after connecting to a new server.
Any help would be appreciated, thanks.
What you write is possible, but it just creates a temporary table on the server where the table is.
You probably want:
select *
into #Server2Table
from server2.database.dbo.table
You can then use #Server2Table in additional queries on the same connection where you copied it (such as the same window in SSMS or the same job step or the same stored procedure). If you need it in a more permanent location, either use a global temporary table (starts with ##) or a "real" table.
This requires the ability to link servers, using something like:
sp_addlinkedserver server2
You would run this on server1. Perhaps your DBA will need to set it up.
I have found that queries often run faster when loading cross-server tables into a temporary table. This is not because temporary tables are stored in memory. This is because there is more information available about a table on a local server for the SQL optimizer to take advantage of.
You could export the data from your query and import that into a database on your first server. You can use the SQL server import/export wizard. Bit convoluted, but if this happens a lot you can use SSIS to automate this move or even simply tick the 'Save this package' box. Once you have the data in your first server you can do whatever you like with it.
