打开SQL SERVER 2014找到你所需要建立数据字典的数据库

  右键→点击 新建查询

在代码区输入如下SQL语句

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,
       (case when (SELECT count(*)
        FROM sysobjects
        WHERE (name in
                (SELECT name
                FROM sysindexes
                WHERE (id = a.id) AND (indid in
                         (SELECT indid
                        FROM sysindexkeys
                        WHERE (id = a.id) AND (colid in
                                  (SELECT colid

                                 WHERE (id = a.id) AND (name = a.name))))))) AND
            (xtype = PK))>0 then √ else  end) 主键,
       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
