Fetch Columns Using IRow::GetColumns (or IRow::Open) and ISequentialStream

Large data can be bound or retrieved using the ISequentialStream interface. For bound columns, the status flag DBSTATUS_S_TRUNCATED indicates that the data is truncated.

Security note Security Note

When possible, use Windows Authentication. If Windows Authentication is not available, prompt users to enter their credentials at run time. Avoid storing credentials in a file. If you must persist credentials, you should encrypt them with the Win32 crypto API.

To fetch columns using IRow::GetColumns (or IRow::Open) and ISequentialStream

  1. Establish a connection to the data source.

  2. Execute the command (in this example, ICommandExecute::Execute() is called with IID_IRow).

  3. Fetch the column data using IRow::Open() or IRow::GetColumns().

    • IRow::Open() can be used to open an ISequentialStream on the row. Specify DBGUID_STREAM to indicate that the column contains a stream of binary data (IStream or ISequentialStream can then be used to read the data from the column).

    • If IRow::GetColumns() is used, the pData element of DBCOLUMNACCESS structure is set to point to a stream object.

  4. Use ISequentialStream::Read() repeatedly to read the specified number of bytes into the consumer buffer.

This example shows how to fetch a single row using IRow. In this example one column at a time is retrieved from the row. This example illustrate the use of IRow::Open() as well as IRow::GetColumns(). To read the column data, the example uses ISequentialStream::Read.

This sample requires the AdventureWorks sample database, which you can download from the Microsoft SQL Server Samples and Community Projects home page.

The first (Transact-SQL) code listing creates a table used by the sample.

Compile with ole32.lib oleaut32.lib and execute the second (C++) code listing. This application 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 third (Transact-SQL) code listing deletes the table used by the sample.
