from user_tab_columns
where Table_Name='用户表'
order by column_name

获取表注释:

select *
from user_tab_comments
where Table_Name='用户表'

order by Table_Name

获取字段注释:

select *
from user_col_comments
where Table_Name='用户表'

order by column_name

 

/* 获取表:*/

select table_name from user_tables; //当前用户的表      

select table_name from all_tables; //所有用户的表  

select table_name from dba_tables; //包括系统表

select table_name from dba_tables where owner='zfxfzb'

/*
user_tables:

table_name,tablespace_name,last_analyzed等

dba_tables:

ower,table_name,tablespace_name,last_analyzed等

all_tables:

all_objects:

*/

/*  获取表字段:*/

select * from user_tab_columns where Table_Name='用户表';

select * from all_tab_columns where Table_Name='用户表';

select * from dba_tab_columns where Table_Name='用户表';

/* user_tab_columns:

table_name,column_name,data_type,data_length,data_precision,data_scale,nullable,column_id等

all_tab_columns :
