On update constraint is not generated in SQL
I am testing the tool and have created two tables (Customer and Project) with one reference (1-m) from customer to project. I also have 2 constraints - one on delete and one for on update. The generated SQL statement does not have the on update constraint clause. Why? Here is the SQL generated.
-- Created by Vertabelo (http://vertabelo.com)
-- Last modification date: 2016-07-18 18:28:56.15 -- tables -- Table: Customer CREATE TABLE Customer ( Cname varchar2(20) NOT NULL, Rating number(2) NULL, CONSTRAINT Customer_pk PRIMARY KEY (Cname) ) ; -- Table: Project CREATE TABLE Project ( PNo number(5) NOT NULL, Pname varchar2(15) NULL, Customer_Cname varchar2(20) NOT NULL, CONSTRAINT Project_pk PRIMARY KEY (PNo) ) ; -- foreign keys -- Reference: Project_Customer (table: Project) ALTER TABLE Project ADD CONSTRAINT Project_Customer FOREIGN KEY (Customer_Cname) REFERENCES Customer (Cname) ON DELETE CASCADE; -- End of file.

Hello,
Oracle 11g does not support ON UPDATE clause. Please see documentation on REFERENCES: https://docs.oracle.com/cd/B28359_01/server.111/b28286/clauses002.htm#CJAIHHGC
You can emulate this behaviour, tutorial: http://www.dba-oracle.com/oracle_tips_cascade_update.htm
We don't disable 'on update' select for Oracle in UI so it might be confusing...
Note: If you choose another DB engine (for example Postgres), Vertabelo will generate ON UPDATE clause.

database
i can add my database to your site for creating relationship in our database

Hello,
You can import an existing database into Vertabelo with help of our Reverse Engineering tool. An article about it: http://www.vertabelo.com/blog/documentation/reverse-engineering
You can also import an sql file when creating new model, screenshot:
I hope this helps

Take over hosting of Vertabelo JOOQ integration
The recent schema changes to the Vertabelo model XML cause the jOOQ code generator to fail to detect primary keys on tables in the model. Furthermore, jOOQ issue #5113 was created to remove the jOOQ-Vertabelo integration from jOOQ in the upcoming version 3.8.
It would be highly beneficial if Vertabelo could take over the maintenance of this plugin in their own repository as suggested in the GitHub issue. As it currently stands the generated code is missing update functionality because of the inability to detect primary keys.

notes and description should support chinese
The generated document does not support Chinese.
