1、查询数据表的属性(名称、说明、是否主键、数据类型、是否自增)
SELECT t1.name columnName,case when t4.id is null then 'false' else 'true' end as pkColumn, case when COLUMNPROPERTY( t1.id,t1.name,'IsIdentity') = 1 then 'true' else 'false' end as autoAdd ,t5.name jdbcType ,cast(isnull(t6.value,'') as varchar(2000)) descr FROM SYSCOLUMNS t1 left join SYSOBJECTS t2 on t2.parent_obj = t1.id AND t2.xtype = 'PK' left join SYSINDEXES t3 on t3.id = t1.id and t2.name = t3.name left join SYSINDEXKEYS t4 on t1.colid = t4.colid and t4.id = t1.id and t4.indid = t3.indid left join systypes t5 on t1.xtype=t5.xtype left join sys.extended_properties t6 on t1.id=t6.major_id and t1.colid=t6.minor_id left join SYSOBJECTS tb on tb.id=t1.id where tb.name='APIInfo' and t5.name<>'sysname'
order by t1.colid asc
若只是简单查询列名及字段类型/长度等信息,直接用下面语句即可
SELECT name,type_name(xtype) AS type,length,(type_name(xtype)+'('+CONVERT(varchar,length)+')') as t FROM syscolumns WHERE (id = OBJECT_ID('view_UserInfo'))
