I am getting DB2 SQL error: SQLCODE: -107 (name too long) exceptions when trying to select rows based on Many-to-one or one-to-many relationships.
Looking at the generated sql I can see that the Alias name generated for the TimeStamp column is one character too long for DB2's max of 18.
The alias when not searching using a many-to-one or one-to-many relationship is SUBMISSION28_48_9_ but for the same property the alias changes to SUBMISSION28_48_10_ which is 19 chars long, one too many for DB2.
Is this a bug in Hibernate's DB2390 dialect? I've seen similar problems in the forums and the only solution is to extend the dialect or Column class.
Is there any other way to get rid of this problem?

This results from a hibernate-bug that has been reported some time ago in this JIRA-issue.

As long as this Problem isn't fixed you can do one of the following:
- Change your column-name from SUBMISSION_TMSTMP to e.g. SUBMISS_TMSTMP or something like that
- Extend DB2390-Dialect (you already said so, I'll post our example-code further down)
- Upgrade to DB2 v8 since it can handle 30-character column-names ;-)

For our Project we chose to override the Dialect-class, since it was the fastest solution. code is as follows:

Then use DB2CustomDialect and all will be well...

Thanks Piet.t,

Renaming our columns is not feasible at this time. I ended up modifying the org.hibernate.mapping.Column class getAlias() method to reduce the string size that it uses from 10 to 8 and it seems to work fine.

public String getAlias() {
String alias = name;
String unique = Integer.toString(uniqueInteger) + '_';
int lastLetter = StringHelper.lastIndexOfLetter(name);
if ( lastLetter == -1 ) {
alias = "column";
}
else if ( lastLetter < name.length()-1 ) {
alias = name.substring(0, lastLetter+1);
}
if ( alias.length() > 8 ) {
alias = alias.substring( 0, 8 - unique.length() );
}
if ( name.equals(alias) ) {
return alias;
}
else {
return alias + unique;
}
}

But I like your solution better since it only affects a specific dialect rather than all of them. I'll give it a try, thanks.
