[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1501) Derby 10 varchar limit is 32672

[Beta (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34081#action_34081 ] 

Beta commented on HHH-1501:
---------------------------

I have this problem fixed by using "long varchar" (it's for strings of any length). I have tested it with a column of 64k and it worked great.

Here is the code:

registerColumnType(Types.VARCHAR, 32672, "varchar($l)");
registerColumnType(Types.VARCHAR, Integer.MAX_VALUE, "long varchar");

I think the best would be to add this code to the DerbyDialect.java

> One need to change DB2Dialect and DerbyDialect to create clob columns, if size of text > 32k:
>         registerColumnType(Types.CHAR, 254, "char(1)");
>         registerColumnType(Types.VARCHAR, 32672, "varchar($l)");
>         registerColumnType(Types.VARCHAR, Integer.MAX_VALUE, "clob($l)");
> (BTW, char limit is 254).
