You cannot return data in a table-valued parameter. Table-valued parameters are input-only; the OUTPUT keyword is not supported. For more information about table-valued parameters, see the following resources. Passing Multiple Rows in Previous Versions of SQL Server ...
For information about table-valued parameters on the server, see Use Table-Valued Parameters (Database Engine).In ODBC, there are two ways that you can send table-valued parameters to the server:All the table-valued parameter data can be in memory at the...
You use a remote procedure call that contains table-valued parameters (TVP) that have many rows. In this scenario, excessive memory usage may occur, and server performance may decrease. If you query the sys.dm_os...
Table-valued parameters provide an easy way to marshal multiple rows of data from a client application to SQL Server without requiring multiple round trips or special server-side logic for processing the data. You can use table-valued parameters to encapsulate rows of data in a client application...
您可以使用 SQL 配接器搭配 BizTalk Server,在 SQL Server 中叫用資料表值函式。 配接器會將資料表值函式公開為可直接在SQL Server上叫用的作業。 如需配接器如何支援資料表值函式的詳細資訊,請參閱使用 SQL 配接器在SQL Server 中執行 Table-Valued 函式。 如需叫用資料...
