If I have a table with data in a database in SQL Server, how can I generate a script that will create the table and add the data too?
If I right click on the table then select Script Table As > Create to > File, that generates a script to just create the table without the data. What I need is a script that creates the table and adds the data that is already existing in the table or 2 separate scripts, one that creates the table and one that adds the data.
Here what you have to do:
right click the database (not the table) and select tasks --> generate scripts
Next --> select the requested table/tables (from select specific database objects)
next --> click advanced --> types of data to script = schema and data
next and finish
Use SSMS scripting feature (Rightclick on database->Tasks->Generate Scripts)
or
use SSMS Tools Pack
Here You can see step by step process of Generate script in SQL Server Management Studio :
Step 1: Right Click on Your Database --> Select Task-->Generate Script..
Step 2: Select Next in Script Wizard
Step 3: Select Script Entire Database
Step 4:Choose Your File Name
and Finish
Now you can use your script file.
Be aware that generating scripts (schema and data) does not export duplicate ROWS
Do a test (only need 2 columns and half a dozen rows) - I wondered what was happening - in the end it turned out to be a good thing in this instance

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 created a small database in dbDesigner which includes 4 tables, and I want to add these tables with their relationships to a database on a SQL Server. How can I do this?
Best practice for this that I am aware of, is using Management Studio's functionality for this.
The following steps will produce a file containing an SQL script you can run on any server you want in order to import the schema (with or without the data).
Right click on you database.
Select Tasks > Generate scripts
Click Next
Choose Script entire database and all database objects
Select Save to file and Single file
If you want to export data as well, click on Advanced and change Types of data to script to Schema and data (default is schema only)
Click Next ... Next.
Run the generated file on the server you want to import the schema to.
I have two SQL Servers (both 2005 version).
I want to migrate several tables from one to another.
I have tried:
On source server I have right clicked on the database, selected Tasks/Generate scripts.
The problem is that under Table/View options there is no Script data option.
Then I used Script Table As/Create script to generate SQL files in order to create the tables on my destination server. But I still need all the data.
Then I tried using:
SELECT *
INTO [destination server].[destination database].[dbo].[destination table]
FROM [source server].[source database].[dbo].[source table]
But I get the error:
Object contains more than the maximum number of prefixes. Maximum is
2.
Can someone please point me to the right solution to my problem?
Try this:
create your table on the target server using your scripts from the Script Table As / Create Script step
on the target server, you can then issue a T-SQL statement:
INSERT INTO dbo.YourTableNameHere
SELECT *
FROM [SourceServer].[SourceDatabase].dbo.YourTableNameHere
This should work just fine.
Just to show yet another option (for SQL Server 2008 and above):
right-click on Database -> select 'Tasks' -> select 'Generate Scripts'
Select specific database objects you want to copy. Let's say one or more tables. Click Next
Click Advanced and scroll down to 'Types of Data to script' and choose 'Schema and Data'. Click OK
Choose where to save generated script and proceed by clicking Next
If you don't have permission to link servers, here are the steps to import a table from one server to another using Sql Server Import/Export Wizard:
Right click on the source database you want to copy from.
Select Tasks - Export Data.
Select Sql Server Native Client in the data source.
Select your authentication type (Sql Server or Windows authentication).
Select the source database.
Next, choose the Destination: Sql Server Native Client
Type in your Server Name (the server you want to copy the table to).
Select your authentication type (Sql Server or Windows authentication).
Select the destination database.
Select Copy data.
Select your table from the list.
Hit Next, Select Run immediately, or optionally, you can also save the package to a file or Sql Server if you want to run it later.
Finish
There is script table option in Tasks/Generate scripts! I also missed it at beginning! But you can generate insert scripts there (very nice feature, but in very un-intuitive place).
When you get to step "Set Scripting Options" go to "Advanced" tab.
Steps described here (pictures can understand, but i do write in latvian there).
Try using the SQL Server Import and Export Wizard (under Tasks -> Export Data).
It offers to create the tables in the destination database. Whereas, as you've seen, the scripting wizard can only create the table structure.
If the tables are already created using the scripts, then there is another way to copy the data is by using BCP command to copy all the data from your source server to your destination server
To export the table data into a text file on source server:
bcp <database name>.<schema name>.<table name> OUT C:\FILE.TXT -c -t -T -S <server_name[ \instance_name]> -U <username> -P <Password>
To import the table data from a text file on target server:
bcp <database name>.<schema name>.<table name> IN C:\FILE.TXT -c -t -T -S <server_name[ \instance_name]> -U <username> -P <Password>
For copying data from source to destination:
use <DestinationDatabase>
select * into <DestinationTable> from <SourceDataBase>.dbo.<SourceTable>
Just for the kicks.
Since I wasnt able to create linked server and since just connecting to production server was not enough to use INSERT INTO i did the following:
created a backup of production server database
restored the database on my test server
executed the insert into statements
Its a backdoor solution, but since i had problems it worked for me.
Since i have created empty tables using SCRIPT TABLE AS / CREATE in order to transfer all the keys and indexes I couldnt use SELECT INTO. SELECT INTO only works if the tables do not exist on the destination location but it does not copy keys and indexes, so you have to do that manualy. The downside of using INSERT INTO statement is that you have to manualy provide with all the column names, plus it might give you some problems if some foreign key constraints fail.
Thanks to all anwsers, there are some great solutions but i have decided to accept marc_s anwser.
You can't choose a source/destination server.
If the databases are on the same server you can do this:
If the columns of the table are equal (including order!) then you can do this:
INSERT INTO [destination database].[dbo].[destination table]
SELECT *
FROM [source database].[dbo].[source table]
If you want to do this once you can backup/restore the source database.
If you need to do this more often I recommend you start a SSIS project where you define source database (there you can choose any connection on any server) and create a project where you move your data there.
See more information here: http://msdn.microsoft.com/en-us/library/ms169917%28v=sql.105%29.aspx
It can be done through "Import/Export Data..." in SQL Server Management Studio
This is somewhat a go around solution but it worked for me I hope it works for this problem for others as well:
You can run the select SQL query on the table that you want to export and save the result as .xls in you drive.
Now create the table you want to add data with all the columns and indexes. This can be easily done with the right click on the actual table and selecting Create To script option.
Now you can right click on the DB where you want to add you table and select the Tasks>Import .
Import Export wizard opens and select next.Select the Microsoft Excel as input Data source and then browse and select the .xls file you have saved earlier.
Now select the destination server and also the destination table we have created already.
Note:If there is any identity based field, in the destination table you might want to remove the identity property as this data will also be inserted . So if you had this one as Identity property only then it would error out the import process.
Now hit next and hit finish and it will show you how many records are being imported and return success if no errors occur.
Yet another option if you have it available: c# .net. In particular, the Microsoft.SqlServer.Management.Smo namespace.
I use code similar to the following in a Script Component of one of my SSIS packages.
var tableToTransfer = "someTable";
var transferringTableSchema = "dbo";
var srvSource = new Server("sourceServer");
var dbSource = srvSource.Databases["sourceDB"];
var srvDestination = new Server("destinationServer");
var dbDestination = srvDestination.Databases["destinationDB"];
var xfr =
new Transfer(dbSource) {
DestinationServer = srvDestination.Name,
DestinationDatabase = dbDestination.Name,
CopyAllObjects = false,
DestinationLoginSecure = true,
DropDestinationObjectsFirst = true,
CopyData = true
};
xfr.Options.ContinueScriptingOnError = false;
xfr.Options.WithDependencies = false;
xfr.ObjectList.Add(dbSource.Tables[tableToTransfer,transferringTableSchema]);
xfr.TransferData();
I think I had to explicitly search for and add the Microsoft.SqlServer.Smo library to the references. But outside of that, this has been working out for me.
Update: The namespace and libraries were more complicated than I remembered.
For libraries, add references to:
Microsoft.SqlServer.Smo.dll
Microsoft.SqlServer.SmoExtended.dll
Microsoft.SqlServer.ConnectionInfo.dll
Microsoft.SqlServer.Management.Sdk.Sfc.dll
For the Namespaces, add:
Microsoft.SqlServer.Management.Common
Microsoft.SqlServer.Management.Smo
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.
