查看表结构：

select a.name 列名, c.name 数据类型,a.max_length 长度,a.is_nullable 是否为空 from sys.columns a, sys.tables b, sys.types c where a.object_id=b.object_id and a.system_type_id=c.system_type_id and b.name='tb_name' order by a.column_id

【SQL|SQL 导出表结构到Excel】查看当前数据库表记录统计：

SELECT a.name, b.rows FROM sysobjects AS a INNER JOIN sysindexes AS b ON a.id = b.id WHERE (a.type = 'u') AND (b.indid IN (0, 1)) ORDER BY b.rows DESC
