Problem with different aliases in select and where clauses ---------------------------------------------------------- Key: HHH-3202 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3202 Project: Hibernate3 Issue Type: Bug Components: build Affects Versions: 3.2.6, 3.2.5 Environment: Oracle 10G, Java 1.5.0_11 Reporter: Neil Hart Our code is usually building the following query: * criteria query */ select this_.ID as ID2_0_, this_.rateDate as rateDate2_0_, this_.ticker as ticker2_0_, this_.currency as currency2_0_, this_.rate as rate2_0_ from BbgDailyRateData this_ where this_.rateDate between to_date('2008-03-24 00:00:00', 'YYYY-MM-DD HH24:MI:SS') and to_date('2008-03-24 23:59:59', 'YYYY-MM-DD HH24:MI:SS') and this_.currency='USD' Every night we bounce our 4 servers and once or twice a week a server will end up trying to run the query as: /* criteria query */ select dailybbgra0_.ID as ID2_0_, dailybbgra0_.rateDate as rateDate2_0_, dailybbgra0_.ticker as ticker2_0_, dailybbgra0_.currency as currency2_0_, dailybbgra0_.rate as rate2_0_ from BbgDailyRateData dailybbgra0_ where this_.rateDate between to_date('2008-03-23 00:00:00', 'YYYY-MM-DD HH24:MI:SS') and to_date('2008-03-23 23:59:59', 'YYYY-MM-DD HH24:MI:SS') and this_.currency='USD' without any changes to code or configuration. We quickly notice the problem and restart the server and the problem goes away. The Java we are running is (using Spring): return getHibernateTemplate().executeFind(new HibernateCallback() { public Object doInHibernate(Session session) throws HibernateException, SQLException { Date from = DateUtils.getStartOfDay(date); Date to = DateUtils.getEndOfDay(date); Criteria criteria = session.createCriteria(DailyBbgRateData.class); criteria.add(Expression.between("date", from, to)); criteria.add(Expression.eq("currency", currency)); return criteria.list(); } }); The mapping is: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="com.creditex.backoffice.defaultswap.BbgCdswData" table="TRADEBBGCDSW"> <cache usage="nonstrict-read-write" /> <id name="id"> <column name="ID" precision="10" scale="0" /> <generator class="assigned"/> </id> <property name="bbgTicker" column="bbgTicker" length="32" not-null="true" /> <property name="settlementDate" column="settlementDate" /> <property name="maturityDate" column="maturityDate" /> <property name="effectiveDate" column="effectiveDate" /> <property name="firstCouponDate" column="firstCouponDate" /> <property name="nextToLastCouponDate" column="nextToLastCouponDate" /> <property name="spread" column="spread" precision="8" scale="3" /> <property name="curveDate" column="curveDate" /> <property name="notional" column="notional" precision="12" scale="0" /> <property name="currency" column="currency" length="3" not-null="true" /> <property name="paymentFrequency" column="paymentFrequency" length="1" not-null="true" /> <property name="recoveryRate" column="recoveryRate" precision="7" scale="6" /> <property name="flatSpread" column="flatSpread" precision="8" scale="3" /> <property name="cnvBpv" column="cnvBpv" precision="10" scale="2" /> <property name="swapCurveBpv" column="swapCurveBpv" precision="10" scale="2" /> <property name="marketValue" column="marketValue" precision="10" scale="2" /> <property name="netAccruedInterest" column="netAccruedInterest" precision="10" scale="2" /> <property name="daysAccrued" column="daysAccrued" precision="4" scale="0" /> <property name="payCurveNumber" column="payCurveNumber" length="4" /> <property name="payCurveMktSide" column="payCurveMktSide" length="20" not-null="true" /> <property name="securityDescription" column="securityDescription" length="32" not-null="true" /> <property name="replSpread" column="replSpread" precision="8" scale="3" /> <property name="buySellFlag" column="buySellFlag" length="1" not-null="true"> <type name="com.creditex.db.hibernate.StringLabeledEnumUserType"> <param name="targetClass">com.creditex.trading.TradeDirection</param> </type> </property> <property name="busDays1" column="busDays1" length="3" /> <property name="busDays2" column="busDays2" length="3" /> <property name="busDays3" column="busDays3" length="3" /> <property name="cashSettledOn" column="cashSettledOn" /> <property name="quotedPrice" column="quotedPrice" precision="12" scale="8" /> <property name="dealRecoveryRate" column="dealRecoveryRate" precision="7" scale="6" /> <property name="priceToSpreadMode" column="priceToSpreadMode" precision="1" scale="0" /> <property name="swapPremium" column="swapPremium" precision="12" scale="2" /> <property name="dateGenMethod" column="dateGenMethod" length="20" not-null="true" /> <property name="payAccrued" column="payAccrued" type="yes_no" length="1" /> </class> </hibernate-mapping> This problem has been persistent from Hibernate 3.2.5.ga and 3.2.6.ga. The Java is 1.5.0_11 and the database is Oracle 10G. This is the first query that we run on startup that has the problem. Once we see this query failing, other queries for different classes fail with the same alias problem. Anyone have any ideas. I think this might be related to HHH-2847; which was also not repeatable but does repeats.
