我如何返回一个表的列名使用SQL Server 2008?即一个表包含这些列- id,名称,地址,国家,我想返回这些数据。

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

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

像这样的东西?

sp_columns @table_name=your table name

不确定2008版是否有更简单的方法。

USE [Database Name]
SELECT COLUMN_NAME,* 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'YourTableName' AND TABLE_SCHEMA='YourSchemaName'

您可以使用下面的代码打印所有列名;您还可以修改代码以打印您喜欢的任何格式的其他细节

    declare @Result varchar(max)='
            '
            select @Result=@Result+''+ColumnName+'
            '
            from
            (
                select
                    replace(col.name, ' ', '_') ColumnName,
                    column_id ColumnId
                from sys.columns col
                    join sys.types typ on
                        col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id
                where object_id = object_id('tblPracticeTestSections')
            ) t
            order by ColumnId
            print @Result

输出

column1
column2
column3
column4

要使用与c#类相同的代码打印表及其列名,请使用以下代码:

    declare @TableName sysname = '<EnterTableName>'
    declare @Result varchar(max) = 'public class ' + @TableName + '
    {'

    select @Result = @Result + '
        public static string ' + ColumnName + ' { get { return "'+ColumnName+'"; } }
    '
    from
    (
        select
            replace(col.name, ' ', '_') ColumnName,
            column_id ColumnId
        from sys.columns col
            join sys.types typ on
                col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id
        where object_id = object_id(@TableName)
    ) t
    order by ColumnId

    set @Result = @Result  + '
    }'

    print @Result

输出:

 public class tblPracticeTestSections
 {
   public static string column1 { get { return "column1"; } }

   public static string column2{ get { return "column2"; } }

   public static string column3{ get { return "column3"; } }

   public static string column4{ get { return "column4"; } }

 }
