选择除某些 PostgreSQL 之外的所有列

Question

我必须比较表，但有一些列我不需要比较，我只知道它们（不是我必须比较的那些）所以我想从表中选择所有列，除了我不需要的列比较。

我想到了这样的事情：

SELECT 'SELECT ' || array_to_string(ARRAY(SELECT 'o' || '.' || c.column_name
    FROM information_schema.columns As c
        WHERE table_name = 'office' 
        AND  c.column_name NOT IN('id', 'deleted')
), ',') || ' FROM officeAs o' As sqlstmt

但是输出SELECT * FROM office As o 不是select a,b,c from office没有id and deleted列。

有没有人知道这个查询有什么问题？

Answer 1

这有效：

CREATE TABLE public.office(id INTEGER, a TEXT, b TEXT, deleted BOOLEAN, c TEXT)

然后：

SELECT 'SELECT ' || STRING_AGG('o.' || column_name, ', ') || ' FROM office AS o'
FROM information_schema.columns
WHERE table_name = 'office'
AND table_schema = 'public'
AND column_name NOT IN ('id', 'deleted')

结果：

SELECT o.a, o.b, o.c FROM office AS o
