我知道已经很晚了，但是我在Oracle上使用这个命令:

select column_name,data_type,data_length from all_tab_columns where TABLE_NAME = 'xxxx' AND OWNER ='xxxxxxxxxx'

SQL Server

使用实例列出数据库中所有用户定义的表。

use [databasename]
select name from sysobjects where type = 'u'

列出一个表的所有列:

use [databasename]
select name from syscolumns where id=object_id('tablename')

SQL Server

sp_help tablename

例子:

select Table_name as [Table] , column_name as [Column] , Table_catalog as [Database], table_schema as [Schema]  from information_schema.columns
where table_schema = 'dbo'
order by Table_name,COLUMN_NAME

只是我的代码

对于mssql Server:

select COLUMN_NAME from information_schema.columns where table_name = 'tableName'

Oracle (PL/SQL)

SELECT column_name
FROM user_tab_cols
WHERE table_name = 'myTableName'

MySQL

SHOW COLUMNS FROM table_name
