這篇文章主要介紹了基于(yu)postgresql查詢(xún)某個(gè)字段屬于哪個(gè)表的基于說(shuō)明，具有很好??的查詢(xún)參考價(jià)值，希望對大家???有所幫助。某個(gè)明一起跟隨小編過(guò)來(lái)看看吧。字段

一、屬于場(chǎng)景還原

前端小林問(wèn)我，個(gè)表它從前端的基于返回的某些字段，想知道那個(gè)表有這個(gè)字段，查詢(xún)它想操作這個(gè)表……

二、某個(gè)明s(╯‵□′)╯ql語(yǔ)句

SELECT *
FROM information_schema. COLUMNS
WHERE COLUMN_NAME = 'storen??ame';

SELECT c.relname AS "表名??",字段a.attname AS "字段名",c.oi(′?_?`)d
FROM pg_class c
LEFT JOIN pg_attribute a ON a.attrelid = c.oi?d
WH(◎_◎;)ERE c.relname NOT LIKE 'pg_%'
-- AND c.relname = 'kx_stor??e'
AND a.attname = 'store?name';

補充：postgresql數據庫查詢(xún)所有字段詳細信息，包括描述

把里邊的屬(′▽?zhuān)?)于public改成相應模式名（默認為public，可不改）

table_name改成對應表名稱(chēng)(?Д?)

SELECT AA.*,個(gè)表BB.DESC FROM
(
SELECT
A.OR( ?ヮ?)DINAL_POSITION AS COL_┐(′ー｀)┌NUM,
A.COLUMN_NAME AS COL_N(????)AME,
A.DATA_TYPE AS COL_TYPE,
A.CHARACTER_MAXIMUM_LENGTH AS COL_LEN,
A.NUMERIC_PRECISION AS COL_PREC,
A.DATETIME_PRE??CISION AS COL_TIME_PREC,
A.IS_NULLABLE AS COL_NULLABLE,
A.COLUMN_DEFAULT AS COL_DEFAULT
FROM INFORMATION_SCHEMA.COLヽ(′▽?zhuān)?ノUMNS A
W??HERE A.TABLE_SCHEMA = 'public' AND A.TABLE_NAME = 'table_name'
)
AS AA LEFT JOIN
(
S??ELECT
OBJSUBID,
DESCRIPTION AS DESC
FROM PG_DESCRIPTION
WHERE OBJOID =
(
SELECT RELID FROM PG_STAT_ALL_TABLE???S WHERE SCHEMANAME = 'public' AND RELNAME = 'table_name'
)
)
AS BB ON AA.COL_NUM = BB.OBJSUBID ORDER BY AA.COL_NUM;
