User-defined functions are routines that accept parameters, perform an action, and return the result as a single scalar value or a result set.
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,...
