SQLServer 获得所有表结构(包括表名及字段)
1 SELECT (case when a.colorder=1 then d.name else null end) 表名, 2 a.colorder 字段序号,a.name 字段名, 3 (case when COLUMNPROPERTY( a.id,a.name,‘IsIdentity‘)=1 then ‘√‘else ‘‘ end) 标识, 4 (case when (SELECT count(*) FROM sysobjects 5 WHERE (name in (SELECT name FROM sysindexes 6 WHERE (id = a.id) AND (indid in 7 (SELECT indid FROM sysindexkeys 8 WHERE (id = a.id) AND (colid in 9 (SELECT colid FROM syscolumns WHERE (id = a.id) AND (name = a.name))))))) 10 AND (xtype = ‘PK‘))>0 then ‘√‘ else ‘‘ end) 主键,b.name 类型,a.length 占用字节数, 11 COLUMNPROPERTY(a.id,a.name,‘PRECISION‘) as 长度, 12 isnull(COLUMNPROPERTY(a.id,a.name,‘Scale‘),0) as 小数位数,(case when a.isnullable=1 then ‘√‘else ‘‘ end) 允许空, 13 isnull(e.text,‘‘) 默认值,isnull(g.[value], ‘ ‘) AS [说明]14 FROM syscolumns a 15 left join systypes b on a.xtype=b.xusertype 16 inner join sysobjects d on a.id=d.id and d.xtype=‘U‘ and d.name<>‘dtproperties‘ 17 left join syscomments e on a.cdefault=e.id 18 left join sys.extended_properties g on a.id=g.major_id AND a.colid=g.minor_id19 left join sys.extended_properties f on d.id=f.class and f.minor_id=020 where b.name is not null21 --WHERE d.name=‘要查询的表‘ --如果只查询指定表,加上此条件22 order by a.id,a.colorder
获得所有数据库表名:
