如何在postgresql中查找具有特定列的表

Question

我正在使用postgresql 9.1.我有一个表的列名.是否有可能找到拥有此列的表格？怎么样？提前致谢.

Answer 1

你也可以

 select table_name from information_schema.columns where column_name = 'your_column_name'

Answer 2

您可以查询系统目录:

select c.relname
from pg_class as c
    inner join pg_attribute as a on a.attrelid = c.oid
where a.attname = <column name> and c.relkind = 'r'

Answer 3

我已使用@Roman Pekar的查询作为基础并添加了架构名称（在我的情况下相关）

select n.nspname as schema ,c.relname
    from pg_class as c
    inner join pg_attribute as a on a.attrelid = c.oid
    inner join pg_namespace as n on c.relnamespace = n.oid
where a.attname = 'id_number' and c.relkind = 'r'

Answer 4

简单地：

$ psql mydatabase -c '\d *' | grep -B10 'mycolname'

如果需要，放大 -B 偏移量以获取表名
