只是对SQL Server中的其他选项做了一点小小的修正(模式前缀变得越来越重要了!):

SELECT name
  FROM sys.columns 
  WHERE [object_id] = OBJECT_ID(N'dbo.tablename');

Oracle (PL/SQL)

SELECT column_name
FROM user_tab_cols
WHERE table_name = 'myTableName'

MySQL

SHOW COLUMNS FROM table_name

对于MySQL，使用:

DESCRIBE name_of_table;

这也适用于Oracle，只要你使用SQL*Plus，或Oracle的SQL Developer。

在MS SQL Server中调用以下代码:

sp_columns [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

SQL Server

sp_help tablename
