SQSERVER2000查詢表結構
簡單型：
Select * from Syscolumns Where ID=OBJECT_ID(N'Ebs_AdCustomer')
列表型：
sp_help 表
詳細型：
SELECT
表名=case when a.colorder=1 then d.name else '' end,
表說明=case when a.colorder=1 then isnull(f.value,'') else '' end,
字段序號=a.colorder,
字段名=a.name,
標識=case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end,
主鍵=case when exists(SELECT 1 FROM sysobjects where xtype='PK' and parent_obj=a.id 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,
類型=b.name,
佔用字節數=a.length,
長度=COLUMNPROPERTY(a.id,a.name,'PRECISION'),
小數位數=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),
允許空=case when a.isnullable=1 then '√'else '' end,
默認值=isnull(e.text,''),
字段說明=isnull(g.[value],'')
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 sysproperties g on a.id=g.id and a.colid=g.smallid
left join sysproperties f on d.id=f.id and f.smallid=0
--where d.name='要查詢的表' --如果只查詢指定表,加上此條件
order by a.id,a.colorder

mysql中查詢表結構

根據已有表創建表結構
sqlserver:
select top 0 * into table2 from product;
select * into table3 from product where 1=2
mysql:
create table table2 select * from users;
