1.獲取表的基本字段屬性 --獲取SqlServer中表結構
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')
運行效果
2.如果還想要獲取字段的描述信息則
--獲取SqlServer中表結構 主鍵，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
運行效果
3.單獨查詢表的遞增字段--單獨查詢表遞增字段
select [name] from syscolumns where
id=object_id(N'你的表名') and COLUMNPROPERTY(id,name,'IsIdentity')=1
運行效果
4.獲取表的主外鍵--獲取表主外鍵約束
exec sp_helpconstraint '你的表名' ;
運行效果
