如果你正在使用postgresql，有可能不止一个模式有相同名称的表，在这种情况下应用下面的查询

SELECT column_name, data_type 
FROM information_schema.columns
WHERE table_name = 'your_table_name' AND table_schema = 'your_schema_name’;

CREATE PROCEDURE [dbo].[Usp_GetColumnName]      
        @TableName varchar(50)
AS
BEGIN   
    BEGIN
        SET NOCOUNT ON
        IF (@TableName IS NOT NULL) 
            select ORDINAL_POSITION OrderPosition,COLUMN_NAME ColumnName from information_schema.columns 
             where table_name =@TableName
             order by ORDINAL_POSITION
    END
END

这似乎比上面的建议要简单一些，因为它使用OBJECT_ID()函数来定位表的id。任何具有该id的列都是表的一部分。

SELECT * 
  FROM syscolumns 
 WHERE id=OBJECT_ID('YOUR_TABLE') 

我通常使用类似的查询来查看是否存在我知道属于新版本的列。这是同一个查询，只是在where子句中添加了{AND name='YOUR_COLUMN'}。

IF EXISTS (
        SELECT * 
          FROM syscolumns 
         WHERE id=OBJECT_ID('YOUR_TABLE') 
           AND name='YOUR_COLUMN'
        )
BEGIN
    PRINT 'Column found'
END

我使用

SELECT st.NAME, sc.NAME, sc.system_type_id
FROM sys.tables st
INNER JOIN sys.columns sc ON st.object_id = sc.object_id
WHERE st.name LIKE '%Tablename%'

一种方法是查询syscolumns:

select
   syscolumns.name as [Column],
   syscolumns.xusertype as [Type],
   sysobjects.xtype as [Objtype]
from 
   sysobjects 
inner join 
   syscolumns on sysobjects.id = syscolumns.id
where sysobjects.xtype = 'u'
and   sysobjects.name = 'MyTableName'
order by syscolumns.name

我用了马丁·史密斯提到的问题，简短一点:

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