SqlPipe Class

Allows managed stored procedures running in-process on a SQL Server database to return results back to the caller. This class cannot be inherited.

Namespace: Microsoft.SqlServer.Server
Assembly: System.Data (in system.data.dll)

public sealed class SqlPipe
public final class SqlPipe
public final class SqlPipe
Not applicable.

An instance of this class is made available to managed stored procedures through the Pipe property of the SqlContext class.

The following example uses SqlConnection and SqlCommand to select rows from a data source in a stored procedure. The example then uses a SqlPipe to execute the command and send the results back to the client.

[Microsoft.SqlServer.Server.SqlProcedure()]
public static void StoredProcExecuteCommand(int rating)
{
    // Connect through the context connection.
    using (SqlConnection connection = new SqlConnection("context connection=true"))
    {
        connection.Open();

        SqlCommand command = new SqlCommand(
            "SELECT VendorID, AccountNumber, Name FROM Purchasing.Vendor " +
            "WHERE CreditRating <= @rating", connection);
        command.Parameters.AddWithValue("@rating", rating);

        // Execute the command and send the results directly to the client.
        SqlContext.Pipe.ExecuteAndSend(command);
        
    }
