Summary: Can't use (b)lobs with Omnis Studio v4

Initial Comment:
Hi.

My company uses PGSQL v8.1 as backend database and Raining Data's Omnis Studio v4.1 as developpement tool (see http://www.omnis.net/. There is a demo version).

LOB (blobs, clobs) can't be used with Postgresql and ODBC, either using lo or bytea. Queries fail or the app' crashes.

I tried different settings with psqlOBDC with no luck.

I've joined my log.

If you have questions or need more details : nte(at)mustinformatique(dot)fr

Thanks.

Nathanael TERRIEN.

It seems to me that it's coming cutted to ODBC driver.
There is no source code of OStudio so I don't know why it is doing it this way. Maybe psqlODBC answer bad information before. But I don't know where and I don't know what OStudio expects.

How do you created lo type? Could you try newer ODBC driver? Could you post minimalistic example (or steps leads to reproduce it)? I don't want to learn OStudio.

I don't think that OStudio sent exactly the same query ;-)

Sorry for the double post before.

Yes, I've read the logs.
You're right, of course, this isn't a correct SQL command and that's the real problem :)

The SQL commande seems to be "cut" and I don't why or by whom (Omnis Studio or the psqlODBC driver) ... but you should know ;).
ANd it's cut just before a blob datatype.
FYI, the exact same command sent by OStudio to MySQL 4.x through ODBC works perfectly and create a "mediumblob" field.

Those logs aside (wich result of an automated VCS Database creation monitored by OSTudio), I've never been able to use lo/bytea blobs with psqlODBC and Omnis Studio : it crash or read/write faulty data.

I have, of course, sent a bug report to Raining Data too but I thought I should inform the great psqlODBC team also ;)

Thanks for looking at this issue, regards,
Nathanael.

Message:
I see no problem with lo or bytea:
[SQLExecute]
CREATE TABLE VCS_ComponentData (vcs_ID int4 NOT NULL,vcs_ChunkID int4 NULL,vcs_ChunkSize int4 NULL,vcs_ChunkChecksum int4 NULL,vcs_Data

This isn't SQL command. Do you read what driver report?

STATEMENT ERROR: errnum=7, errmsg='Error while executing the query'
CONN ERROR: errnum=108, errmsg='ERROR: syntax error at end of input au caractčre 137'

Please don't create new bug report. Either log in before you report bug or send additional information to pgsql-odbc mailing list.
