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

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 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 can i transfer single table data from one Database to other database with same table name?
I have a database with data and other one has no data.
They are not exactly the same as but one table is the same
Thanks
There are many ways to export a table. Some are,
Using SELECT INTO Query
Select * into Database1.Department from Database2.Department
Using SQL Server Export / Import wizard
a. From SQL Server Management Studio, right-click on the database name in the object explorer, then choose Tasks -> Export Data
b. Choose a Data Source and Destination
c. Select the source table and follow the steps and execute the package

Edited Note:
The above methods are for Microsoft SQL Server.
I'm working on some project. But for some test purposes I need some tables from client oracle DB to my local DB. So that I could perform operations on that tables for test purposes.
Can you please help me ?
I would suggest to get a dump of your client DB with expdp. But you need to have access to conolse of the client computer.
If you have no Access you could try to set up an database link from you database to the client one (http://docs.oracle.com/cd/B19306_01/server.102/b14200/statements_5005.htm).
Exect you have now your db link "MyDBLink" and want to copy the dual table you can use the create table as select Statement to create a copy to your System:
create table myCopyOfDual as select * from dual#MyDBLink
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.
