MSSQL查询表名、字段、备注、类型、默认值等信息

格式一

SELECT c.name '字段名', TYPE_NAME(c.system_type_id)+ '(' + CONVERT(VARCHAR(20),c.max_length)  + ')' '字段类型',
CASE c.is_nullable WHEN 0 THEN '否' ELSE '是' END '是否允许为空',convert(varchar(100), isnull(cmts.text,'')) '默认值',p.value '备注'

LEFT JOIN sys.syscomments cmts ON c.default_object_id = cmts.id
WHERE
