Hi,

I want to use hibernate to store a big data, which may be between 15,000 to 60,000 characters. currently I am using DAO to store in in chunks of 2000 characters. So if the data is 15000 the data is divided in 2000 chunks and store into database with multiple rows.

I will appreciate if anyone can provide their suggestion to use hibernate in this scenario.

Regards
Hitesh

Hi Hitesh,

The best thing to do is use a text field, this datatype can hold unlimited data.
If you generate the database with Hibernate you will get this automatically then the length is specified and very big. for example:

@Column(length=50000)

I must say, that i've never worked with such big fields, but it should work.
If you have a legacy problem(i.e. you cannot change your database layout), you should work something out with Collections, but that's probably not really easy...)

Regards,
Bas
