Oracle使用笔记

1、查询全部字段名

select c.TABLE_NAME
from all_constraints p, all_constraints c
where p.table_name = 'TIME_TABLE_LAYOUT'
  and p.OWNER = SYS_CONTEXT('USERENV', 'CURRENT_SCHEMA')
  and c.OWNER = SYS_CONTEXT('USERENV', 'CURRENT_SCHEMA')
  and c.constraint_type = 'R'
  and p.CONSTRAINT_NAME = c.R_CONSTRAINT_NAME ;

2、查询字段注释

select * from user_col_comments where Table_Name = '表名'
