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。
Two new diagnostic fields, SQL_DIAG_SS_TABLE_COLUMN_NUMBER and SQL_DIAG_SS_TABLE_ROW_NUMBER, have been added to diagnostic records. These fields help you to determine which table-valued parameter column values are associated with errors and warnings....
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 time SQLExecD...
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 fol...
For a table-valued parameter, we need a user-defined table type (UDTT). UDTT can be created with the following T-SQL statement. CREATE TYPE UDTT_Country AS TABLE( CountryName nvarchar(100), CurrencyName nvarchar(50) ) GO Note: Syntax for creating a user-defined table type is similar ...
