一、场景还原
前端小林问我，它从前端的返回的某些字段，想知道那个表有这个字段，它想操作这个表……
二、sql语句SELECT *
FROM informatio
一、场景还原
前端小林问我，它从前端的返回的某些字段，想知道那个表有这个字段，它想操作这个表……
二、sql语句
SELECT * FROM information_schema. COLUMNS WHERE COLUMN_NAME = 'storename';
SELECT c.relname AS "表名",a.attname AS "字段名",c.oid FROM pg_class c LEFT JOIN pg_attribute a ON a.attrelid = c.oid WHERE c.relname NOT LIKE 'pg_%' -- AND c.relname = 'kx_store' AND a.attname = 'storename';
补充：postgresql数据库查询所有字段详细信息，包括描述
把里边的public改成相应模式名（默认为public，可不改）
table_name改成对应表名称
SELECT AA.*,BB.DESC FROM ( SELECT A.ORDINAL_POSITION AS COL_NUM, A.COLUMN_NAME AS COL_NAME, A.DATA_TYPE AS COL_TYPE, A.CHARACTER_MAXIMUM_LENGTH AS COL_LEN, A.NUMERIC_PRECISION AS COL_PREC, A.DATETIME_PRECISION AS COL_TIME_PREC, A.IS_NULLABLE AS COL_NULLABLE, A.COLUMN_DEFAULT AS COL_DEFAULT FROM INFORMATION_SCHEMA.COLUMNS A WHERE A.TABLE_SCHEMA = 'public' AND A.TABLE_NAME = 'table_name' ) AS AA LEFT JOIN ( SELECT OBJSUBID, DESCRIPTION AS DESC FROM PG_DESCRIPTION WHERE OBJOID = ( SELECT RELID FROM PG_STAT_ALL_TABLES WHERE SCHEMANAME = 'public' AND RELNAME = 'table_name' ) ) AS BB ON AA.COL_NUM = BB.OBJSUBID ORDER BY AA.COL_NUM;
以上为个人经验，希望能给大家一个参考，也希望大家多多支持好代码网。如有错误或未考虑完全的地方，望不吝赐教。
