MonetDB 存储过程 return table

Question

来自 MonetDB 用户的：

You cannot use an ordinary select query in a procedure. You can change the contents of tables or set variables, but you cannot use a query like this. Remember, with such a query, there is a result, and where should the result go?

在 MonetDB 上创建类型的正确方法是什么：

CREATE XXXX
BEGIN
   SELECT * FROM table;
END

谢谢

Answer 1

这似乎更像是 VIEW 的工作，例如

CREATE VIEW XXXX AS SELECT * FROM table;

SELECT * FROM XXXX;

如果你想创建一个函数，你可以这样做：

CREATE FUNCTION XXXX() 
RETURNS TABLE (name string)
RETURN TABLE (SELECT name from tables);

SELECT * FROM XXXX();

注意第二种情况，需要在函数定义中指定返回table的schema
