---元數(shù)據(jù)所做的工作
發(fā)布元數(shù)據(jù)會導(dǎo)致以下表中產(chǎn)生數(shù)據(jù)
執(zhí)行腳本即執(zhí)行建表語句
下面只介紹發(fā)布元數(shù)據(jù)所產(chǎn)生的數(shù)據(jù)
--先根據(jù)表名查出發(fā)布的元數(shù)據(jù)的組件id ，之后的查詢都是通過compentid來查詢數(shù)據(jù)
componentid 指得是點擊空白處的組件ID
假設(shè)表名是pt_app_account
select componentid from md_class where defaulttablename='pt_app_account';
?--f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf

?(select defaulttablename from md_class where id in
?(select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf'));
---枚舉
?select * from? MD_ENUMVALUE where id in
?(select id from md_class where componentid='f1d9ad1e-70ff-428e-a58b-67a0fb8bdbdf');
----列數(shù)據(jù)
