在SQL Server中…

SELECT [name] AS [Column Name]
FROM syscolumns
WHERE id = (SELECT id FROM sysobjects WHERE type = 'V' AND [Name] = 'Your table name')

Type = 'V'表示视图 Type = 'U'表示表

select * from <表名> where rownum = 1;

你可以这样做:

describe EVENT_LOG

or

desc EVENT_LOG

注意:只适用于你知道表名，特别是Oracle。

该信息存储在ALL_TAB_COLUMNS系统表中:

SQL> select column_name from all_tab_columns where table_name = 'DUAL';

DUMMY

或者你可以描述表，如果你使用SQL*PLUS:

SQL> desc dual
Name                               Null?    Type
----------------------------------------------------- -------- ---------------------- -------------
DUMMY                               VARCHAR2(1)

select column_name,* from information_schema.columns
 where table_name = 'YourTableName'
order by ordinal_position

对甲骨文

SELECT column_name FROM user_tab_cols WHERE table_name=UPPER('tableName');
