准备并执行SQL

Question

当我运行以下

时

PREPARE fooplan (dataset text) AS
create or replace VIEW $dataset$_view as (
  select * from $dataset$ one where not exists(
     select* from $dataset$ two where
     ((one.x <= two.x and one.y <two.y) OR
     (one.x < two.x and one.y <=two.y))) ORDER BY y DESC, x DESC);

在psql中按Enter键，不会出现错误或成功语句。我觉得终端期待我添加一些不确定的东西？ 任何人都可以看到缺少的东西吗？

Answer 1

您已创建准备好的陈述，然后必须执行：

EXECUTE fooplan('foobar');
