一.摘要表值参数(Table-valued parameters)简称TVP,是SQL Server2008中引入的一种新特性,它提供了一种内置的方式,让客户端应用可以只通过单独的一条参化数SQL语句,就可以向SQL Server发送多行数据。 二.简介在表值参数出现以前,当需要发送多行数据到SQL Server,我们只能使用一些替代方案来实现: (1) 使用一连串的...

sql server FUNCTION 表参数 SQL Server FUNCTION 表参数的实现指南 引言 在SQL Server 中,函数(Function)是一个重要的编程工具。它们能封装特定的逻辑并返回结果。而通过表参数(Table-Valued Parameter),你可以在函数中传递表格数据,这样可以处理更复杂的数据结构。本文将教会你如何实现 SQL Server 的表参数函数。
By using multiple records in a single statement or routine, round trips to the server can be reduced. You can declare this using a table that is defined by the user. In 2008, the initialization of User-defined table types (UDTTs) and TVPs Table-valued parameters (TVP) were done for us...
Support for Table-Valued Parameters is available starting with Microsoft JDBC Driver 6.0 for SQL Server. You can't 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 f...
After you create a table type, you can declare table-valued parameters based on that type. The following Transact-SQL fragment demonstrates how to declare a table-valued parameter in a stored procedure definition. Note that the READONLY keyword is required for declaring a table-valued parameter....
