This section contains the following examples:
- A. Copying table rows into a data file (with a trusted connection)
- B. Copying table rows into a data file (with Mixed-mode Authentication)
- C. Copying data from a file to a table
- D. Copying a specific column into a data file
- E. Copying a specific row into a data file
- F. Copying data from a query to a data file
- G. Creating a non-XML format file
- H. Creating an XML format file
- I. Using a format file to bulk import with bcp
A. Copying table rows into a data file (with a trusted connection)
B. Copying table rows into a data file (with mixed-mode authentication)
The following example illustrates the out option on the AdventureWorks.Sales.Currency table. This example creates a data file named Currency.dat and copies the table data into it using character format.
The example assumes that you are using mixed-mode authentication, you must use the -U switch to specify your login ID. Also, unless you are connecting to the default instance of SQL Server on the local computer, use the -S switch to specify the system name and, optionally, an instance name.
bcp AdventureWorks.Sales.Currency out Currency.dat -c -U<login_id> -S<server_name\instance_name>
The system will prompt you for your password.
C. Copying data from a file to a table
The following example illustrates the in option by using the file created in the preceding example (Currency.dat). First, however, this example creates an empty copy of the AdventureWorks Sales.Currency table, Sales.Currency2, into which the data is copied. The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command.
To create the empty table, in Query Editor, enter the following command:
USE AdventureWorks;
GO
SELECT * INTO AdventureWorks.Sales.Currency2
FROM AdventureWorks.Sales.Currency WHERE 1=2
To bulk copy the character data into the new table, that is to import the data, enter the following command at a command prompt:
bcp AdventureWorks.Sales.Currency2 in Currency.dat -T -c
To verify that the command succeeded, display the contents of the table in Query Editor, and enter:
USE AdventureWorks;
GO
SELECT * FROM Sales.Currency2
D. Copying a specific column into a data file
To copy a specific column, you can use the queryout option. The following example copies only the Name column of the Sales.Currency table into a data file. The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command.
At the Windows command prompt, enter:
bcp "SELECT Name FROM AdventureWorks.Sales.Currency" queryout Currency.Name.dat -T -c
E. Copying a specific row into a data file
To copy a specific row, you can use the queryout option. The following example copies only the row for the contact named Jarrod Rana from the AdventureWorks.Person.Contact table into a data file (Jarrod Rana.dat). The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command.
At the Windows command prompt, enter:
bcp "SELECT * FROM AdventureWorks.Person.Contact WHERE FirstName='Jarrod' AND LastName='Rana' " queryout "Jarrod Rana.dat" -T -c
F. Copying data from a query to a data file
To copy the result set from a Transact-SQL statement to a data file, use the queryout option. The following example copies the names from the AdventureWorks.Person.Contact table, ordered by last name then first name, into the Contacts.txt data file. The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command.
At the Windows command prompt, enter:
bcp "SELECT FirstName, LastName FROM AdventureWorks.Person.Contact ORDER BY LastName, Firstname" queryout Contacts.txt -c -T
G. Creating a non-XML format file
The following example creates a non-XML format file, Currency.fmt, for the Sales.Currency table in the AdventureWorks database. The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command.
At the Windows command prompt, enter:
bcp AdventureWorks.Sales.Currency format nul -T -c -f Currency.fmt

H. Creating an XML format file
The following example creates an XML format file named Currency.xml for the Sales.Currency table in the AdventureWorks database. The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command.
At the Windows command prompt, enter:
bcp AdventureWorks.Sales.Currency format nul -T -c -x -f Currency.xml

| To use the -x switch, you must be using a bcp 9.0 client. For information about how to use the bcp 9.0 client, see "Remarks."

I. Using a format file to bulk import with bcp
To use a previously created format file when importing data into an instance of SQL Server, use the -f switch with the in option. For example, the following command bulk copies the contents of a data file, Currency.dat, into a copy of the Sales.Currency table (Sales.Currency2) by using the previously created format file (Currency.xml). The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command.
At the Windows command prompt, enter:
bcp AdventureWorks.Sales.Currency2 in Currency.dat -T -f Currency.xml
| Note: |
| Format files are useful when the data file fields are different from the table columns; for example, in their number, ordering, or data types. For more information, see Format Files for Importing or Exporting Data [ http://msdn2.microsoft.com/en-us/library/ms190393.aspx ] .
