DB2 : column/@length should have been honored for CLOB

Created: 25/Jun/09 08:30 PM   Updated: 20/Oct/10 09:30 AM   Resolved: 13/Oct/10 11:15 AM
Component/s: Types
Affects Version/s: 1.1.3
Fix Version/s: 2.2.0.m2

File Attachments: 1. Zip Archive (2 kB)

Environment: Linux, Java 5, DB2

Datastore: IBM DB2
Severity: Production

 Description  « Hide
JDO specification 2.2 (page 223) has specified
"The length attribute declares" "the maximum number of characters in the datastore representation of String types"

<column name="string" jdbc-type="CLOB" length="1024"/>
generates "CLOB(1073741824)" which should have been "CLOB(1024)"

At the same time, it would be nice to honor column/@length for BLOB too such as
<column name="bytes" jdbc-type="BLOB" length="1024"/>

Can't test against 1.1.4 due to NUCRDBMS-205

This is only for DB2; other datastores like Oracle don't allow precision on BLOB/CLOB

Was fixed as part of NUCRDBMS-209
