CREATE VIEW — 定义一个新视图 大纲 CREATE [ OR REPLACE ] [ TEMP | TEMPORARY ] [ RECURSIVE ] VIEW name [ ( column_name [, ...] ) ] [ WITH ( view_option_name [= view_option_value ] [, ... ] ) ] AS query [ WITH [ CASCADED | LOCAL ] CHECK OPTION ] 描述 CREATE VIEW定义...
创建一个由数字1到100组成的递归视图。 CREATE RECURSIVE VIEW public.nums_1_100 (n) AS VALUES (1) UNION ALL SELECT n+1 FROM nums_1_100 WHERE n < 100; 说明 上述SQL语句中,尽管递归的视图名称是模式限定的,但它内部的自引用不是模式限定的。这是因为隐式创建的CTE的名称不能是模式限定的。

目前view_option_name支持的参数仅有security_barrier,当VIEW试图提供行级安全时,应使用该参数。 取值范围:boolean类型,TRUE、FALSE query 为视图提供行和列的SELECT或VALUES语句。 视图解耦功能下不支持CTE重名。例如: CREATETABLEt1(a1INT,b1INT);CREATETABLEt2(a2INT,b2INT,c2INT);CREATEORREPLACEVIEWv1ASWITHtmp...

create table as with用法`CREATE TABLE AS`语句通常用于创建新表,并将查询的结果作为新表的内容填充。`WITH`语句则用于在查询中创建临时的命名查询结果,通常称为公共表表达式(CTE)或者子查询。 这两者的结合通常在数据库中使用,例如在SQL中,可以按照以下方式组合使用: 假设我们有一个数据库,其中有一个名为`...
