简单，不需要sys变量:

SHOW COLUMNS FROM suppliers;

select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='tableName'

这比从sys。列，因为它直接显示DATA_TYPE。

--This is another variation used to document a large database for conversion (Edited to --remove static columns)

SELECT o.Name                   as Table_Name
     , c.Name                   as Field_Name
     , t.Name                   as Data_Type
     , t.length                 as Length_Size
     , t.prec                   as Precision_
FROM syscolumns c 
     INNER JOIN sysobjects o ON o.id = c.id
     LEFT JOIN  systypes t on t.xtype = c.xtype  
WHERE o.type = 'U' 
ORDER BY o.Name, c.Name

--In the left join, c.type is replaced by c.xtype to get varchar types

SELECT TOP (0) [toID]
      ,[sourceID]
      ,[name]
      ,[address]
  FROM [ReportDatabase].[Ticket].[To]

简单，不需要任何系统表

SELECT name
FROM sys.columns
WHERE object_id = OBJECT_ID('TABLE_NAME')

TABLE_NAME是你的表

这个SO问题缺少以下方法:

-- List down all columns of table 'Logging'
select * from sys.all_columns where object_id = OBJECT_ID('Logging')
