SQL0670N creating table with 250 columns

Jo
Hi.

I'm getting the following error when creating a table with 250 columns
.. I have tried creating it in a 32K tablespace , still the same issue.
Is this a limitation in DB2? I am using DB2 v8.2 FP 9a.

SQL0670N The row length of the table exceeded a limit of "32677"
bytes.

(Table space "".) SQLSTATE=54010

Any advice will be appreciated
Thanks a lot.

Hi Everyone.
Thanks a lot for your inputs. We have reduced the size of all the
DBCLOB columns from 1G to 30K. The table creation is successful and
data also has been loaded successfully. However when viewing this data
from the control center we run into error about lob locator limit
exceeding. From command line, the select goes through without this
issue. We tried playing around with the lobcachesize parameter but
still no effect. Any suggestions would be appreciated !!
Thanks again.
How many rows are you selecting back in one shot?
In DB2 V8 for LUW I think 32000 locators are supported. In DB2 9 it's
some big number in the millions.

You could add the following to your [common] section in the db2cli.ini file:

PATCH2=50

That will cause LOB locators to be freed upon the next fetch.

The CLP doesn't use LOB locators as does CLI (which is employed by the
control center).

Another alternative in your own application is to roll a commit/rollback
operation more frequently.

Serge, there is no change to the limit of 32100 - according to the V9 docs
(http://publib.boulder.ibm.com/infoce.../v9/index.jsp). Am I
missing something?

>From the control center we double-click on the table, the first 100
rows are fine, when we click to fetch the next 100 rows we run into
this error about lob locators. From CLP fetching all the rows is fine.
There are over 2200 rows. Is there any workaround to bypass this issue
when selecting from the control center? We are still using v8.2

If the PATCH2=50 is set then all the columns have an error message
inside them when viewed from the control center. The message says "
SQL0423N..."
