---------------------------------------

Hey George,

Thanks for mentioning that! I did a quick research and found that on some databases JPA creates the column with different type based on the 'length' attribute of the @Column annotation.

Should we always set it to MAX_VALUE or we should let the user configure it with an option (defaulting to MAX_VALUE)? Something like:

field lob --named <field-name> [--length <length>]

Cheers,
Ivan

> Right now Forge's field plugin supports most of the common Java/JPA types as commands (string, number, date, etc.). It also supports JPA relationships (one-to-many, etc.). However, a very common scenario for a Java EE developer is to store an image or other binary object into the database.
> In such situations the JPA best practices say that it should be declared as byte array field and annotated with @Lob.
> Forge should be able to generate such fields when the command:
> {code:java}
> field lob --named <field-name> 
> {code}
> is issued
> The exact name of the command (lob or bytearray or anything) is subject to discussion.
