This sample shows how to fetch a single row using IRow
. This sample is not supported on IA64.
SQL Server samples and sample databases must be downloaded and installed before you can view or work with them. For more information, see

For more information on this sample, see How to: Fetch Columns Using IRow::GetColumns (or IRow::Open) and ISequentialStream
in Books Online.
This sample uses Transact-SQL and Visual C++.
Before running this sample, make sure the following software is installed:
Building the Sample
- This sample connects to your computer's default SQL Server instance (on some Windows operating systems, you will need to change (localhost) or (local) to the name of your SQL Server instance). To connect to a named instance, change the connection string
from L"(local)" to
L"(local)\\name" , where name is the named instance. By default, SQL Server Express installs to a named instance.
- Make sure your INCLUDE environment variable includes the directory that contains sqlncli.h.
- The sample requires you to execute the following Transact-SQL statements, which you can find in the sample's scripts directory: * USE AdventureWorks
IF EXISTS (SELECT name FROM sysobjects WHERE name = 'MyTable')
DROP TABLE MyTable
CREATE TABLE MyTable
/* Enter data. */
INSERT INTO MyTable
'11/1/1999 11:52 AM',
GO * In SQL Server Management Studio, load and execute the Scripts\setup.sql script or execute the following command in a Command Prompt window: * sqlcmd -E -I -i Scripts\setup.sql *
- If you are using Visual Studio, load the FetchColumns_A.sln file and build it.
- If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt, passing it the FetchColumns_A.sln file: * MSBuild FetchColumns_A.sln *
Running the Sample
- From Visual Studio, invoke Start Without Debugging (CTRL+F5).
- If you built with MSBuild.exe, invoke FetchColumns_A.exe.
