How to fetch the data from one database and insert in to another database table? I can't to do this. Please help me in transferring data from one to another.
There are several ways to do this, below are two options:
Option 1
- Right click on the database you want to copy
Choose 'Tasks' > 'Generate scripts'
'Select specific database objects'
Check 'Tables'
Mark 'Save to new query window'
Click 'Advanced'
Set 'Types of data to script' to 'Schema and data'
Next, Next
You can now run the generated query on the new database.
Option 2
Right click on the database you want to copy
'Tasks' > 'Export Data'
Next, Next
Choose the database to copy the tables to
Mark 'Copy data from one or more tables or views'
Choose the tables you want to copy
Finish
Example for insert into values in One database table into another database table running on the same SQL Server
insert into dbo.onedatabase.FolderStatus
(
[FolderStatusId],
[code],
[title],
[last_modified]
)
select [FolderStatusId], [code], [title], [last_modified]
from dbo.Twodatabase.f_file_stat
For those on Azure, follow these modified instructions from Virus:
Open SSMS.
Right-click the Database you wish to copy data from.
Select Generate Scripts >> Select Specific Database Objects >> Choose the tables/object you wish to transfer.
strong text
In the "Save to file" pane, click Advanced
Set "Types of data to script" to Schema and data
Set "Script DROP and CREATE" to Script DROP and CREATE
Under "Table/View Options" set relevant items to TRUE. Though I recommend setting all to TRUE just in case. You can always modify the script after it generates.
Set filepath >> Next >> Next
Open newly created SQL file. Remove "Use" from top of file.
Open new query window on destination database, paste script contents (without using) and execute.
if both databases are on same server and you want to transfer entire table (make copy of it) then use simple select into statement ...
select * into anotherDatabase..copyOfTable from oneDatabase..tableName
You can then write cursor top of sysobjects and copy entire set of tables that way.
If you want more complex data extraction & transformation, then use SSIS and build appropriate ETL in it.
You can use visual studio 2015. Go to Tools => SQL server => New Data comparison
Select source and target Database.
You can backup and restore the database using Management Studio.
Again from Management Studio you can use "copy database".
you can even do it manually if there is a reason to do so. I mean manually create the target db and manually copying data by sql statements...
can you clarify why you ask this? Is it that you dont have expierience in doing it or something else?
There are multiple options and depend on your needs.
See the following links:
Copying Data Between Servers
Copy tables from one database to another in SQL Server.
These solutions are working in case when target database is blank.
In case when both databases already have some data you need something more complicated http://byalexblog.net/merge-sql-databases
This can be achieved by a T-SQL statement, if you are aware that FROM clause can specify database for table name.
insert into database1..MyTable
select from database2..MyTable
Here is how Microsoft explains the syntax:
https://learn.microsoft.com/en-us/sql/t-sql/queries/from-transact-sql?view=sql-server-ver15
If the table or view exists in another database on the same instance of SQL Server, use a fully qualified name in the form database.schema.object_name.
schema_name can be omitted, like above, which means the default schema of the current user. By default, it's dbo.
Add any filtering to columns/rows if you want to. Be sure to create any new table before moving data.
Doing this programmatically between two different databases could involve a scheduled job using a linked server. But linked servers require DBA-level knowledge to set up. If you can't use a linked server, just write a program that 1. Reads a row from the source table and 2. Inserts it into the target table. The programmer just needs to use a connection string that has INSERT privileges into the target database table. I have solved this problems using both approaches.

I am currently in the process of moving tables, views, and stored procedures from one database in SQL Server to another database on the same server. A couple weeks ago, I had already started manually moving some of these procdures, and I am unsure of which ones I have moved so far. I want to write a query that compares the tables I have already moved to database 2 to the ones in database 1, and lists the stuff in database 1 I have not moved yet. I guess I am confused as to where to start, as I don't have much experience in using the system tables.
The easiest way would be to disregard which you already did, script them all out using the SSMS Generate Scripts task, and do a DROP/CREATE or check for existence just to be sure.
Open SSMS
Open the object explorer, connect to your instance,
and open the Databases folder
Right click on the database that
has the object you want to move over and click Tasks, then click
Generate Scripts
Click the Select specific database objects radio button and select all the tables/procs/etc you want to move over. Click Next
Click Advanced, change Script Drop and CREATE to SCRIPT DROP AND CREATE (or change Check for object existence to TRUE), then change Types of Data to Script to Schema and Data
Click Save to File radio button and script it all out
Here's something that should work.
select
name
,type_desc
from
CurrentDatabase.sys.objects
where
is_ms_shipped <> 1
and type_desc in ('VIEW','SQL_STORED_PROCEDURE','USER_TABLE') --add in trigers, TVF, etc that you may want...
except
select
name
,type_desc
from
YourNewDatabase.sys.objects
where
is_ms_shipped <> 1
and type_desc in ('VIEW','SQL_STORED_PROCEDURE','USER_TABLE') --add in trigers, TVF, etc that you may want...
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;
I want to get a backup of a single table with its data from a database in SQL Server using a script.
How can I do that?
SELECT * INTO mytable_backup FROM mytable
This makes a copy of table mytable, and every row in it, called mytable_backup. It will not copy any indices, constraints, etc., just the structure and data.
Note that this will not work if you have an existing table named mytable_backup, so if you want to use this code regularly (for example, to backup daily or monthly), you'll need to run drop mytable_backup first.
You can use the "Generate script for database objects" feature on SSMS.
Right click on the target database
Select Tasks > Generate Scripts
Choose desired table or specific object
Hit the Advanced button
Under General, choose value on the Types of data to script. You can select Data only, Schema only, and Schema and data. Schema and data includes both table creation and actual data on the generated script.
Click Next until wizard is done
There are many ways you can take back of table.
BCP (BULK COPY PROGRAM)
Generate Table Script with data
Make a copy of table using SELECT INTO, example here
SAVE Table Data Directly in a Flat file
Export Data using SSIS to any destination
You can create table script along with its data using following steps:
Right click on the database.
Select Tasks > Generate scripts ...
Click next.
Click next.
In Table/View Options, set Script Data to True; then click next.
Select the Tables checkbox and click next.
Select your table name and click next.
Click next until the wizard is done.
For more information, see Eric Johnson's blog.
Put the table in its own filegroup. You can then use regular SQL Server built in backup to backup the filegroup in which in effect backs up the table.
To backup a filegroup see:
https://learn.microsoft.com/en-us/sql/relational-databases/backup-restore/back-up-files-and-filegroups-sql-server
To create a table on a non-default filegroup (its easy) see:
Create a table on a filegroup other than the default
Another approach you can take if you need to back up a single table out of multiple tables in a database is:
Generate script of specific table(s) from a database (Right-click database, click Task > Generate Scripts...
Run the script in the query editor. You must change/add the first line (USE DatabaseName) in the script to a new database, to avoid getting the "Database already exists" error.
Right-click on the newly created database, and click on Task > Back Up...
The backup will contain the selected table(s) from the original database.
To get a copy in a file on the local file-system, this rickety utility from the Windows start button menu worked:
"C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\DTSWizard.exe"
I'm importing a big flat file (about 400.000 rows and 255+ columns) into SQL Server Management Studio through the import wizard.
To get the right variables I use Suggest types, but I have found that I need to search through all the rows to get the right variable types. It takes a very long time. Is there a way to avoid this or do it faster?
Furthermore, my real goal is to transfer data from one sql server database to another on another computer. I do this by exporting it as a flat file. But maybe this is stupid since I lose the information about the correct format?
Thanks!
According to Copy one database to another database:
There are several ways to do this, below are two options:
Option 1
Right click on the database you want to copy
Choose 'Tasks' > 'Generate scripts'
'Select specific database objects'
Check 'Tables'
Mark 'Save to new query window'
Click 'Advanced'
Set 'Types of data to script' to 'Schema and data'
Next, Next
You can now run the generated query on the new database.
Option 2
Right click on the database you want to copy
'Tasks' > 'Export Data'
Next, Next
Choose the database to copy the tables to
Mark 'Copy data from one or more tables or views'
Choose the tables you want to copy
Finish
Backup your database and restores it on the other server (the tager server must be equal or higher version) or simply copy the database files to other server and attached it (when copying database files, you must ensures that either you have detached the database or stop the sql server service).
In "Back UP" I only get a bak file, but I would like to create .sql file
Use SQL Server's Generate Scripts commend
right click on the database; Tasks -> Generate Scripts
select your tables, click Next
click the Advanced button
find Types of data to script - choose Schema and Data.
you can then choose to save to file, or put in new query window.
results in CREATE and INSERT statements for all table data selected in bullet 2.
This is a possible duplicate of: SQL script to get table content as "SELECT * FROM tblname"
To do a full database backup to File/Query you can use the 'Generate Scripts...' option on the Database.
Open SQL Server Management studio, right click on the database and choose 'Tasks->Generate Scripts...'
Then use the wizard to backup the database. You can script the whole database or parts of it. Two important options: In the 'Advanced' section, you will probably want to ensure 'Type of backup = 'Schema and Data' and the 'Script Statistics' is on.
This will produce a *.sql file that you can use as a backup that includes the schema and table data.
Ok, I read through most of these, but I had no "advanced button". But, there is still a way to do it, it's just a little hard to find, so here you go:
You can generate a script from a database, see http://msdn.microsoft.com/en-us/library/ms178078.aspx
If you want to create a script of your database you right-click on the databases and Generate Scripts (it's in different sub-menus depending on what version of SQL and Enterprise Manager / SQL Server Management studio you're using).
That will, however, only get you the database objects. It will not generate scripts for data. Backing up a database will give you all of the database objects as well as the data, depending on what recovery model your database is set to.
This fellow may have achieved what you are trying to do by creating the backup, and then restoring it and giving it a new name.
This approach copies the data along with all of the database objects.
If you want a file with insert statements for your data have a look here:
This procedure generates INSERT statements using existing data from the given tables and views. Later, you can use these INSERT statements to generate the data. It's very useful when you have to ship or package a database application. This procedure also comes in handy when you have to send sample data to your vendor or technical support provider for troubleshooting purposes.
