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。 整体流程 下面的表格简要描述实现 SQL Server FUNC
last name, and email address in separate columns. In the application, you want to display the full name as first name and last name. Usually developers will use a plus (+) sign to concatenate strings, but SQL Server provides useful string functions CONCAT() and CONCAT_WS() for this purpo...

在SQL Server中,普通的表值函数(table-valued function)是可以使用表提示(Hints-Table)的,那么CLR类型的表值函数(table-valued function)是否也可以使用表提示(Hints-Table)呢? 相信很多人都没有留意过这个问题。 下面我以YourSQLDba中现成的CLR表值函数来演示一下这个问题。如果自己手头有自定义CLR表值函数的,也...
