将表数据从一个 SQLServer 导出到另一个 SQLServer

我有两个 SQLServer (都是2005版本)。

我想将几个表从一个迁移到另一个。

我试过了:

  • 在源服务器上我右键单击了数据库，选择了 Tasks/Generate scripts。 问题是在 Table/View options下没有 Script data选项

  • 然后，我使用 Script Table As/Create script生成 SQL 文件，以便在目标服务器上创建表。但我还是需要所有的数据。

然后我试着用:

SELECT *
INTO [destination server].[destination database].[dbo].[destination table]
FROM [source server].[source database].[dbo].[source table]

但我得到了一个错误:

对象包含的前缀数超过最大值。最大值为 2.

谁能给我指出解决问题的正确方法？

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

For copying data from source to destination:

use <DestinationDatabase>
select * into <DestinationTable> from <SourceDataBase>.dbo.<SourceTable>

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 this:

  1. create your table on the target server using your scripts from the Script Table As / Create Script step

  2. 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.

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>

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.

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.

Just to show yet another option (for SQL Server 2008 and above):

  1. right-click on Database -> select 'Tasks' -> select 'Generate Scripts'
  2. Select specific database objects you want to copy. Let's say one or more tables. Click Next
  3. Click Advanced and scroll down to 'Types of Data to script' and choose 'Schema and Data'. Click OK
  4. Choose where to save generated script and proceed by clicking Next

It can be done through "Import/Export Data..." in SQL Server Management Studio

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

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
