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: java.sql.SQLSyntaxErrorException: ORA-00904: "TRUE": invalid identifier at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:445) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:396) at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:879) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:450) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:192) at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:531) at oracle.jdbc.driver.T4CStatement.doOall8(T4CStatement.java:193) at oracle.jdbc.driver.T4CStatement.executeForDescribe(T4CStatement.java:873) at oracle.jdbc.driver.OracleStatement.executeMaybeDescribe(OracleStatement.java:1167) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1289) at oracle.jdbc.driver.OracleStatement.executeQuery(OracleStatement.java:1491) at oracle.jdbc.driver.OracleStatementWrapper.executeQuery(OracleStatementWrapper.java:406) at org.apache.commons.dbcp2.DelegatingStatement.executeQuery(DelegatingStatement.java:207) at org.apache.commons.dbcp2.DelegatingStatement.executeQuery(DelegatingStatement.java:207) at org.apache.commons.dbcp2.DelegatingStatement.executeQuery(DelegatingStatement.java:207) at com.xpn.xwiki.store.migration.hibernate.R72001XWIKI12228DataMigration$R72001Work.getVisibleSpaces(R72001XWIKI12228DataMigration.java:129) at com.xpn.xwiki.store.migration.hibernate.R72001XWIKI12228DataMigration$R72001Work.createVisibleSpaces(R72001XWIKI12228DataMigration.java:182) at com.xpn.xwiki.store.migration.hibernate.R72001XWIKI12228DataMigration$R72001Work.execute(R72001XWIKI12228DataMigration.java:106) at org.hibernate.impl.SessionImpl.doWork(SessionImpl.java:1997) ... 28 more Mirec
