Alias Problem... Hibernate is replacing our alias at one place but not at another place --------------------------------------------------------------------------------------- Key: HHH-1902 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1902 Project: Hibernate3 Type: Bug

Components: query-hql Versions: 3.0.3 Environment: Hibernate 3.0.3 Database Platform : MSSQL Server 2000 Reporter: Paras Dhawan Attachments: testhibernate.rar I have a query which contains a sub query in the select list... I have defined an alias of the sub query as _sqry1 now I am putting an Order By clause in the query.... Order By is on the result of the sub query and I have given the alias of the sub query in the Order By clause My Query is which i am giving to Hibernate is SELECT (SELECT SUM(_0_ServiceCharge_0_service.chargeAmount) FROM Service AS _0_service , ServiceCharge AS _0_ServiceCharge_0_service WHERE _transportService_Challan = _0_service AND _0_service = _0_ServiceCharge_0_service.service) AS _sqry1 FROM Challan AS _Challan LEFT OUTER JOIN _Challan.transportService AS _transportService_Challan ORDER BY _sqry1 Now the problem is that Hibernate is replacing my aliases.... it replaced my alias of the sub query from _sqry1 to col_0_0_ .... it replaced this alias in the select list but not in the Order By clause... i.e. it replaced the alias where I defined it but it did not replaced the alias where I used it.... so the place where I am using the alias it is giving an error as undefined alias The generated SQL by Hibernate: select (select SUM(servicecha3_.ChargeAmount) from Services service2_, ServiceCharges servicecha3_ where transports1_.TransportServiceId=service2_.ServiceId and service2_.ServiceId=servicecha3_.serviceGroupTablePKId) as col_0_0_ from Challans challan0_ left outer join TransportServices transports1_ on challan0_.TransportServiceId=transports1_.TransportServiceId left outer join Services transports1_1_ on transports1_.TransportServiceId=transports1_1_.ServiceId order by _sqry1 when I manually replaced my alias in the Order By clause then my query run successfully Either Hibernate should not replace my alias, even if it is replacing then it must replace all the occurences I cannot use criteria, I cannot use named queries, i cannot use native sql because my queries are formed at run time, I have to specify a HQL only... This is bug in Hibernate Hibernate version: 3.0.5 Name and version of the database that I am using: MS SQL Server 2000 Full stack trace of any exception that occurs: Exception in thread "main" org.hibernate.exception.SQLGrammarException: could not execute query at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:67) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.loader.Loader.doList(Loader.java:2148) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2029) at org.hibernate.loader.Loader.list(Loader.java:2024) at org.hibernate.loader.hql.QueryLoader.list(QueryLoader.java:375) at org.hibernate.hql.ast.QueryTranslatorImpl.list(QueryTranslatorImpl.java:308) at org.hibernate.engine.query.HQLQueryPlan.performList(HQLQueryPlan.java:153) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1106) at org.hibernate.impl.QueryImpl.list(QueryImpl.java:79) at com.daffodilwoods.framework.utils.HibernateUtil.main(HibernateUtil.java:296) Caused by: java.sql.SQLException: [DataDirect][SQLServer JDBC Driver][SQLServer]Invalid column name '_sqry1'. at com.ddtek.jdbc.base.BaseExceptions.createException(Unknown Source) at com.ddtek.jdbc.base.BaseExceptions.getException(Unknown Source) at com.ddtek.jdbc.sqlserver.tds.TDSRequest.processErrorToken(Unknown Source) at com.ddtek.jdbc.sqlserver.tds.TDSRequest.processReplyToken(Unknown Source) at com.ddtek.jdbc.sqlserver.tds.TDSRPCRequest.processReplyToken(Unknown Source) at com.ddtek.jdbc.sqlserver.tds.TDSRequest.processReply(Unknown Source) at com.ddtek.jdbc.sqlserver.tds.TDSRPCNonCursorExecuteRequest.submitPrepare(Unknown Source) at com.ddtek.jdbc.sqlserver.tds.TDSRPCExecuteRequest.doPrepExec(Unknown Source) at com.ddtek.jdbc.sqlserver.tds.TDSRPCExecuteRequest.execute(Unknown Source) at com.ddtek.jdbc.sqlserver.SQLServerImplStatement.execute(Unknown Source) at com.ddtek.jdbc.base.BaseStatement.commonExecute(Unknown Source) at com.ddtek.jdbc.base.BaseStatement.executeQueryInternal(Unknown Source) at com.ddtek.jdbc.base.BasePreparedStatement.executeQuery(Unknown Source) at org.hibernate.jdbc.AbstractBatcher.getResultSet(AbstractBatcher.java:139) at org.hibernate.loader.Loader.getResultSet(Loader.java:1669) at org.hibernate.loader.Loader.doQuery(Loader.java:662) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) at org.hibernate.loader.Loader.doList(Loader.java:2145) ... 8 more
