SQL SERVER中的用户定义函数(User Defined Functions 简称UDF)分为标量函数(Scalar-Valued Function)和表值函数(Table-Valued Function)。其中表值函数又分为Inline table-valued functions和Multistatement table-valued functions。 用户定义函数(UDF)在 SQL Server 中发挥重要的作用。用户定义函数可以用于执行复杂的逻辑,...
1、table-valued function can join table, but Scalar-valued functions can not join table. SELECT*FROMTestCount(5) A,TestCount_1 BWHEREA.ID=B.ID 2、table-valued function can not nest in table, but Scalar-valued functions can do it. SELECTDBO.TestCount_SVF(5),*FROMTestCount_1 3、call ...

> is it possible to open a recordset and loop through the records in a scalar valued function? Yes, but using SQL Server, in most cases, this is a very bad idea! You can use CURSOR for the task. check the following docs: https://learn.microsoft.com/sql/t-sql/l...
