As the name suggests: table-valued returns table, however Scalar-valued returns a single value, such as a string, integer, or bit value. 1、table-valued function As to create table-valued function, there are 2 ways, look at the example below please, it’s suitable for simple logic: USE...
自定义函数(User-Defined Function)有两种,一种是标量UDF(Scalar-valued Functions)和表值UDF(Table-valued Functions),前者只返回单个数据值,而后者则返回一个表。前面演示了标量自定义函数,javascript:void(0),现在下面两个实例均演示表值自定义函数, 代码 SETANSI_NULLSON GO SETQUOTED_IDENTIFIERON GO CREATEFUN...

U-SQL allows table-valued functions (TVF) to be called as primary rowset expressions even outside of a SELECT’sFROMclause. Note that the statements that make up the definition of a U-SQL Table-valued function are always inlined where they are called, while preserving the visibility rules...
表值函数(table-valued function, TVF),顾名思义就是指返回值是一张表的函数,在Oracle、SQL Server等数据库中屡见不鲜。 而在Flink的上一个稳定版本1.13中,社区通过FLIP-145提出了窗口表值函数(window TVF)的实现,用于替代旧版的窗口分组(grouped window)语法。
