1.获取表的基本字段属性 复制代码 代码如下: --获取SqlServer中表结构 SELECT syscolumns.name,systypes.name,syscolumns.isnullable, syscolumns.length FROM syscolumns, systypes WHERE syscolumns.xusertype = systypes.xusertyp
1.获取表的基本字段属性复制代码 代码如下:--获取SqlServer中表结构 SELECT syscolumns.name,systypes.name,syscolumns.isnullable,syscolumns.length FROM syscolumns, systypes WHERE syscolumns.xusertype = systypes.xusertype AND syscolumns.id = object_id('你的表名')运行效果
2.如果还想要获取字段的描述信息则复制代码 代码如下:--获取SqlServer中表结构 主键，及描述declare @table_name as varchar(max)set @table_name = '你的表名' select sys.columns.name, sys.types.name, sys.columns.max_length, sys.columns.is_nullable, (select count(*) from sys.identity_columns where sys.identity_columns.object_id = sys.columns.object_id and sys.columns.column_id = sys.identity_columns.column_id) as is_identity , (select value from sys.extended_properties where sys.extended_properties.major_id = sys.columns.object_id and sys.extended_properties.minor_id = sys.columns.column_id) as description from sys.columns, sys.tables, sys.types where sys.columns.object_id = sys.tables.object_id and sys.columns.system_type_id=sys.types.system_type_id and sys.tables.name=@table_name order by sys.columns.column_id运行效果
3.单独查询表的递增字段复制代码 代码如下:--单独查询表递增字段select [name] from syscolumns where id=object_id(N'你的表名') and COLUMNPROPERTY(id,name,'IsIdentity')=1运行效果
4.获取表的主外键复制代码 代码如下:--获取表主外键约束exec sp_helpconstraint '你的表名' ;运行效果
