USE [Database]

SELECT TABLE_NAME,
       TABLE_SCHEMA,
       [Column_Name],
       [Data_type]
FROM   INFORMATION_SCHEMA.COLUMNS
WHERE  TABLE_SCHEMA = 'dbo'  

DECLARE @col NVARCHAR(MAX);
SELECT @col= COALESCE(@col, '') + ',' + COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS WHERE  Table_name = 'MxLocations';
SELECT @col;

由于SysColumns已弃用，请使用Sys. columns。All_Columns:

Select  
 ObjectName       = Object_Name(Object_ID)  
,T.Name  
,C.*  
,T.*  
From   
           Sys.All_Columns C  
Inner Join Sys.Types       T  On T.User_Type_Id = C.User_Type_Id  
Where [Object_ID] = Object_ID('Sys.Server_Permissions')  
--Order By Name Asc  

选择“* From Sys”。类型将产生user_type_id =类型的ID。这在数据库中是唯一的。系统数据类型:user_type_id = system_type_id。

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

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’;

试试这个

select * from <tablename> where 1=2
