SqlDataRecord 对象

SqlDataRecord 对象表示一行数据及其相关元数据。

托管存储过程可以发送到并非来自于 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("GivenName", 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)
