I have the following definition:
@Column(name = "password", length = 80)
byte[] password;
When I use EclipseLink to create the tables (mysql) I get a table with a longblob. A tinyblob would suffice.
How do I have to specify the length?
I know that I could add a columnDefinition but I’d like to keep it database/sql agnostic.
If you want specific type for blob column, columnDefinition should be used. Problem with length is that it is only for strings. This is also told in API.
