SQL Server自定义函数(Table-valued Functions) 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_NU...

Cannot process the query because it references the common language runtime (CLR) table-valued function "yUtl.clr_GetFolderList" with a hint through view "yUtl.v_test". 其实这个是因为视图对象使用了WITH(NOLOCK)的话,就会自动转换为给视图内部对象加上WITH(NOLOCK),那么就会出现上面的错误,如果像存储...
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...

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。
