如何在 Redshift 中列出所有表及其创建者（或所有者）

Question

我认为这很简单，但我找不到在 Redshift 中列出所有表及其创建者（或所有者）的方法。欢迎任何帮助/见解。

Answer 1

这是 pg_tables 表，这是 SQL：

select tablename, tableowner From pg_tables 

Answer 2

您可以通过运行以下脚本列出 Redshift 表、视图及其所有者：

SELECT n.nspname AS schema_name
 , pg_get_userbyid(c.relowner) AS table_owner
 , c.relname AS table_name
 , CASE WHEN c.relkind = 'v' THEN 'view' ELSE 'table' END 
   AS table_type
 , d.description AS table_description
 FROM pg_class As c
 LEFT JOIN pg_namespace n ON n.oid = c.relnamespace
 LEFT JOIN pg_tablespace t ON t.oid = c.reltablespace
 LEFT JOIN pg_description As d 
      ON (d.objoid = c.oid AND d.objsubid = 0)
 WHERE c.relkind IN('r', 'v') 
ORDER BY n.nspname, c.relname ;

Answer 3

如果您要从特定模式搜索视图和过程源代码，您可以使用以下查询。我发现它非常有用。

SELECT
    n.nspname AS schema_name
    , 'view' AS object_type
    , c.relname AS object_name
    , pg_get_userbyid(c.relowner) AS object_owner
    , v.view_definition AS object_definition
FROM
    pg_class AS c
    LEFT JOIN pg_namespace n
        ON n.oid = c.relnamespace
    LEFT JOIN information_schema.VIEWS v
        ON c.relname = v.table_name
WHERE
    c.relkind IN ('v') /* view */
    AND n.nspname = '<schema_name>'
    AND REGEXP_INSTR(v.view_definition, 'regular expression search string here') > 0
UNION
SELECT
    n.nspname AS schema_name
    , 'procedure' AS object_type
    , p.proname AS object_name
    , pg_get_userbyid(p.proowner) AS object_owner
    , p.prosrc AS object_definition
FROM
    pg_catalog.pg_namespace n
    JOIN pg_catalog.pg_proc p
        ON pronamespace = n.oid
    JOIN pg_user b
        ON b.usesysid = p.proowner
WHERE
    n.nspname = '<schema_name>'
    AND REGEXP_INSTR(p.prosrc, 'regular expression search string here') > 0
ORDER BY 1,2,3,4
