两个过程你参考看看：
--删除所有表的内容
create procedure Delete_Table_Content;
As
  declare @table_Name Char(50),@SqlStr Char(80)

  /* 定义游标变量  dbo.table_name_list 是你存放待删除表名的表 */
  Declare table_Name_Cur cursor for
  select  table_Name   from dbo.table_name_list

  /* 打开游标结果集 */
  open table_name_cur
  /* 取第一条数据到 @table_name 变量中 */
  fetch next from table_name_cur into @table_name

  while ( @@fetch_status<>-1 )
  begin
    If ( @@fetch_status<>-2 )
  begin
    /* 合并表名到 SQL 字符串中 */
    select @SqlStr = 'delete from '+@table_name
    /* 执行删除操作 */
    EXECUTE SP_ExecuteSql @tSqlStr
  end
   /* 取下一表名 */
   fetch next from table_name_cur into @table_name
  end
  /* 关闭游标 */
  close table_name_cur
  /* 释放游标占用内存*/
  deallocate table_name_cur

--列出SQL SERVER 所有表，字段名，主键，类型，长度，小数位数等信息

--在查询分析器里运行即可,可以生成一个表，导出到EXCEL中

SELECT

      (case when a.colorder=1 then d.name else ' end)表名,

      a.colorder 字段序号,

      a.name 字段名,

      (case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else ' end) 标识,

      b.name 类型,

      a.length 占用字节数,

      COLUMNPROPERTY(a.id,a.name,'PRECISION') as 长度,

      isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小数位数,

      (case when a.isnullable=1 then '√'else ' end) 允许空,

      isnull(e.text,') 默认值,

      isnull(g.[value],') AS 字段说明

FROM  syscolumns  a left join systypes b

inner join sysobjects d
