获取mssqlserver数据库表的字段名称，字段说明，数据类型，主键等表的信息

sql脚本：

SELECT
TableName=case   when   a.colorder=1   then   d.name   else   ''   end,---表名
TableShowsThat=case   when   a.colorder=1   then   isnull(f.value,'')   else   ''   end,---表说明
TheSerialNumberField=a.colorder,---字段序号
FieldName=a.name,---字段名
Identification=case   when   COLUMNPROPERTY(   a.id,a.name,'IsIdentity')=1   then   '√'else   ''   end,
PrimaryKey=case   when   exists(SELECT   1   FROM   sysobjects   where   xtype='PK'   and   name   in   (
SELECT   name   FROM   sysindexes   WHERE   indid   in(
SELECT   indid   FROM   sysindexkeys   WHERE   id   =   a.id   AND   colid=a.colid
)))   then   '√'   else   ''   end,---标识主键
[Type]=b.name,---数据类型
TakeUpTheNumberOfBytes=a.length,---占用字节数
[Length]=COLUMNPROPERTY(a.id,a.name,'PRECISION'),---长度
DecimalDigits=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),---小数位数
AllowEmpty=case   when   a.isnullable=1   then   '√'else   ''   end,---允许空
[Default]=isnull(e.text,''),---默认值
FieldsThat=isnull(g.[value],'')---字段说明
FROM   syscolumns   a
left   join   systypes   b   on   a.xusertype=b.xusertype
inner   join   sysobjects   d   on   a.id=d.id     and   d.xtype='U'   and     d.name<>'dtproperties'
left   join   syscomments   e   on   a.cdefault=e.id
left   join   sys.extended_properties   g   on   a.id=g.major_id   and   a.colid=g.minor_id
left   join   sys.extended_properties   f   on   d.id=f.major_id   and   f.minor_id=0 
where   d.name='Accounts_User'         --如果只查询指定表,加上此条件
order   by   a.id,a.colorder
