在MS SQL Server中调用以下代码:

sp_columns [tablename]

SQL Server

SELECT 
    c.name 
FROM
    sys.objects o
INNER JOIN
    sys.columns c
ON
    c.object_id = o.object_id
AND o.name = 'Table_Name'

or

SELECT 
    COLUMN_NAME 
FROM 
    INFORMATION_SCHEMA.COLUMNS
WHERE 
    TABLE_NAME  = 'Table_Name'

第二种方法是ANSI标准，因此应该适用于所有符合ANSI标准的数据库。

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

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');

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。

SQL Server

sp_help tablename
