1) Hi, we are trying to use dyna-beans for domain objects and are looking for any
utils to easily store them into a database (Commons- SQL seemed to be the closest with
its support for dyna beans)
2)I am trying to think how commons-sql can be used to insert a dynabean into a table
and return the identity column inserted in one statement so that it can be used as a
foreign key reference to insert several other rows.
3) Taking the example provided with commons- sql for these two tables
create table author
(
author_id INTEGER NOT NULL ,
name VARCHAR (50) NOT NULL ,
organisation VARCHAR (50) NULL ,
PRIMARY KEY (author_id)
);
create table book
(
book_id INTEGER NOT NULL IDENTITY,
isbn VARCHAR (15) NOT NULL ,
author_id INTEGER NOT NULL ,
title VARCHAR (255) DEFAULT 'N/A' NOT NULL ,
FOREIGN KEY (author_id)
REFERENCES author (author_id)
);
The code to insert dyna-beans to this table
- insert author
author = dynaSql.newInstance("author");
author.set("author_id", new Integer(2));
-- is there a way to return this column from the db on insert of the author dyna-bean
so that it can used in book inserts.
author.set("name", "Ian Rankin");
dynaSql.insert(author);
-- insert a book
DynaBean book = dynaSql.newInstance("book");
book.set("author_id", new Integer(1));
book.set("isbn", "ISBN-ABCDEF");
book.set("title", "The Importance of being Earnest");
dynaSql.insert(book);
-----
book = dynaSql.newInstance("book");
book.set("author_id", new Integer(2));
book.set("isbn", "ISBN-XYZ");
book.set("title", "The Hanging Garden");
dynaSql.insert(book);
Questions:
Is there a way to return this column from the db on insert of the author dyna-bean so
that it can used in book inserts.
Something similato this in SQL :
INSERT INTO author (col1, col2, col3) VALUES (?, ?, ?)
CALL IDENTITY()
Also is there a way to insert a collection of Dyna-Beans into a db like a batch insert
with common-sql.
Thanks again for your time and energy.
