Beta build 181 and Clob and Blob Support

Hi I was just trying out  the latest Build -> Beta build 181.
Getting errors on Tables and Stored procedures that have Clob and Blob types defined.
Do you support these types? I do not remember getting these errors in  Build 134.

Could you also please provide a list of types that you are NOT going to support:
ie:
Clob
Blob
XML

etc.

Thanks,

Matt

Hi,

Thanks for the Answer.

Just wondering though, why the following types:

CLOB
NCLOB
BLOB
BFILE

will not be supported? Especially, the CLOB and BLOB? Also XMLTYPE

Thanks Again

Matt,

We decided to hold off on supporting LOB's because of the complexity of implementing the LOB storage clauses. The individual LOB types will be very simple to add, it's capturing the definition of all the many, many sub-statements that we decided to wait on.

Hi Dwight,

Thanks for the speedy response.

Yes, the defintions for the Lobs can get complex.

Is there some workaround for this?

If not, puts me in a bit of a pickle though, a number of the tables in our db have clobs and blobs. Guess will then have to wait for V2.

Thanks Again,

Matt

Matt,

We are going to tackle this for version 2.0. Until then there is a limited work-around. You can basically develop everything else, and manually add your LOBs to the scripts that the Oracle DSP generates. It's not great, but it does get you there. Dwight

Is this information still valid? I'm currently using 1.5.0.500 beta. It appears to import clobs and builds properly, however the DDL deployment script doesn't seem to work when attempting to create the table.

Timmy,

You are correct. This post is very old and v1.5.0 does support LOBs. We have been working on a serious QA cycle and have addressed many of the issues around LOBs. What issues are you having with the v1.5.0.501 Beta build?

Sorry for the long delay. Our server doesn't seem to be kicking out new post announcements to the forum leaders.
