UAP元数据

---元数据所做的工作
发布元数据会导致以下表中产生数据
执行脚本即执行建表语句
下面只介绍发布元数据所产生的数据
--先根据表名查出发布的元数据的组件id ，之后的查询都是通过compentid来查询数据
componentid 指得是点击空白处的组件ID
假设表名是pt_app_account
select componentid from md_class where defaulttablename='pt_app_account';
 --f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf
---md_table
 select * from  md_table where id in
 (select defaulttablename from md_class where id in
 (select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf'));
---枚举
 select * from  MD_ENUMVALUE where id in
 (select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf');
----列数据
 select * from  md_column where tableid in
 (select defaulttablename from md_class where id in
 (select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf'));
 --主子表关联关系表
 select * from md_db_relation where startattrid in
 (select id from  md_property where classid in
 (select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf'));
 --属性表
 select * from  md_property where classid in
 (select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf');
 select * from  md_association where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf';
--
 select * from  MD_ACCESSORPARA where id in
  (select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf');
---class表
 select * from  md_bizitfmap where classid in
  (select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf');
 --
select * from  md_ormap where classid in
 (select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf');
---class表
 select * from  md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf';
---组件 select * from  md_component where id='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf';
