1、根据类全名定位对应类型id
select local_id,fullname from ubf_md_class where fullname like '命名空间'
2、根据类型id定位对应数据表字段属性
select local_id,local_class_id,name,length from ubf_md_attribute where local_class_id =1001908020010001
3、更新对应数据表字段类型长度
update ubf_md_attribute set length =9999 where local_class_id =1001908020010001 and local_id=1001908020010021 --local_class_id 类型id，local_id 属性id
