SqlDataRecord 对象
适用范围:SQL Server
SqlDataRecord 对象表示单个数据行及其相关元数据。
托管存储过程可能会发送到不是来自 SqlDataReader 的客户端结果集。 SqlDataRecord 类以及 SqlPipe 对象的 SendResultsStart、SendResultsRow 和 SendResultsEnd 方法允许存储过程将自定义结果集发送到客户端。
有关详细信息,请参阅 .NET Framework SDK 文档中的 Microsoft.SqlServer.Server.SqlDataRecord 类参考文档。
示例
下面的示例创建一个新雇员记录并将其返回到调用方。
C#
[Microsoft.SqlServer.Server.SqlProcedure]
public static void CreateNewRecordProc()
{
// Variables.
SqlDataRecord record;
// Create a new record with the column metadata. The constructor
// is able to accept a variable number of parameters.
record = new SqlDataRecord(new SqlMetaData("EmployeeID", SqlDbType.Int),
new SqlMetaData("Surname", SqlDbType.NVarChar, 20),
new SqlMetaData("GivenName", SqlDbType.NVarChar, 20),
new SqlMetaData("StartDate", SqlDbType.DateTime) );
// Set the record fields.
record.SetInt32(0, 0042);
record.SetString(1, "Funk");
record.SetString(2, "Don");
record.SetDateTime(3, new DateTime(2005, 7, 17));
// Send the record to the calling program.
SqlContext.Pipe.Send(record);
}
Visual Basic
<Microsoft.SqlServer.Server.SqlProcedure()> _
Public Shared Sub CreateNewRecordVBProc ()
' Variables.
Dim record As SqlDataRecord
' Create a new record with the column metadata. The constructor is
' able to accept a variable number of parameters
record = New SqlDataRecord(New SqlMetaData("EmployeeID", SqlDbType.Int), _
New SqlMetaData("Surname", SqlDbType.NVarChar, 20), _

New SqlMetaData("StartDate", SqlDbType.DateTime))
' Set the record fields.
record.SetInt32(0, 42)
record.SetString(1, "Funk")
record.SetString(2, "Don")
record.SetDateTime(3, New DateTime(2005, 7, 17))
' Send the record to the calling program.
SqlContext.Pipe.Send(record)
End Sub
