Hi, I don't know if the code which I've pasted is old or not, but after
searching for occurence in lib directory,
I found this source file
https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi…,
which seems very actual.
In the call stack of the exception which I get is mentioned
"R72001XWIKI12228DataMigration", which fails on the error ORA-00904:
"TRUE": invalid identifier.
Oracle doesn't support such configuration to know that TRUE means boolean
true. Oracle doesn't have any knowledge or concept of booleans. You cannot
use true in pure sql statement because it is not compatible whithin
database you support.
Hibernate allows through qyery.substitution property to provide custom
mapping of those literals, but it works on HQLs not on SQLs.

even older in another form than a filter).
I'm really far from an Oracle expert, could this be related to some
Oracle configuration to enable/disable boolean literal support ?
In the meantime would be great if you could create an issue on
http://jira.xwiki.org/browse/XWIKI.

Hi, when migrating XWiki from version 7.1.1 to
7.2, I get the error
bellow.
My XWiki runs on Oracle DB. It seems that
there's error in using TRUE
literal in sql statements, which is not supported on Oracle. Could you
please fix this. I located the error in the following method
in R72001XWIKI12228DataMigration.java
private String createSpaceQuery(boolean hidden)
{
StringBuilder query = new StringBuilder("select DISTINCT XWD_WEB from
xwikidoc where");
if (hidden) {
query.append(" XWD_WEB not in (" + createSpaceQuery(false) + ")");
} else {
query.append(" XWD_HIDDEN <> *true *OR XWD_HIDDEN IS NULL");
}
return query.toString();
}
The raised error:
