推荐答案

据我所知，Cassandra中的程序没有直接的等价物。如果需要SELECT，INSERT或UPDATE语句中的函数，则可以创建UDF，请参阅创建功能 [ ^ ]



另一方面，如果你需要一个DML语句块，你可以使用 BATCH [ ^ ]。但是，由于这不是存储或命名的代码段，因此它不像您可以通过名称调用的过程。相反，它更像是SQL Server中的匿名T-SQL块。

As far as I know, there is no direct equivalent for a procedure in Cassandra. If you need a function in a SELECT, INSERT or UPDATE statement, you can create an UDF, see CREATE FUNCTION[^]

On the other hand if you need a block of DML statements, you could use BATCH[^]. However, since this is not a stored or named piece of code it's not like a procedure you could call by name. Instead it's more like an anonymous T-SQL block in SQL Server.
