Craig Uss [https://community.jboss.org/people/craigmuss] created the discussion "SqlResultMapping not working" To view the discussion, visit: https://community.jboss.org/message/728678#728678 -------------------------------------------------------------- I am trying to use @SqlResultMapping with one of my queries: query = this      .getEntityManager()      .createNativeQuery(        "SELECT DISTINCT proj.*, mess.trigger_date"          + "FROM ci_project as proj LEFT JOIN ci_project_message as mess "          + "on proj.message_no = mess.message_no "          + "WHERE proj.survey_contact = :userId",        "surveyManagement").setParameter("userId", userId);   I made a SqlResultMapping for this query: @SqlResultSetMapping(name = "surveyManagement", entities = {     @EntityResult(entityClass = CiProject.class),     @EntityResult(entityClass = CiProjectMessage.class, discriminatorColumn = "MESSAGE_NO", fields = { @FieldResult(name = "triggerDate", column = "trigger_date") }) }) I am getting the following error when I try to execute this query: Caused by: org.hibernate.exception.SQLGrammarException: could not execute query at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:90) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.loader.Loader.doList(Loader.java:2236) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2130) at org.hibernate.loader.Loader.list(Loader.java:2125) at org.hibernate.loader.custom.CustomLoader.list(CustomLoader.java:312) at org.hibernate.impl.SessionImpl.listCustomQuery(SessionImpl.java:1724) at org.hibernate.impl.AbstractSessionImpl.list(AbstractSessionImpl.java:165) at org.hibernate.impl.SQLQueryImpl.list(SQLQueryImpl.java:175) at org.hibernate.ejb.QueryImpl.getResultList(QueryImpl.java:94) ... 252 more Caused by: java.sql.SQLException: Column 'MESSAGE1_4_1_' not found. at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1073) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:987) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:982) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:927) at com.mysql.jdbc.ResultSetImpl.findColumn(ResultSetImpl.java:1144) at com.mysql.jdbc.ResultSetImpl.getInt(ResultSetImpl.java:2815) at org.jboss.resource.adapter.jdbc.WrappedResultSet.getInt(WrappedResultSet.java:698) at org.hibernate.type.IntegerType.get(IntegerType.java:51) at org.hibernate.type.NullableType.nullSafeGet(NullableType.java:184) at org.hibernate.type.NullableType.nullSafeGet(NullableType.java:173) at org.hibernate.loader.Loader.getKeyFromResultSet(Loader.java:1120) at org.hibernate.loader.Loader.getRowFromResultSet(Loader.java:587) at org.hibernate.loader.Loader.doQuery(Loader.java:723) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:258) at org.hibernate.loader.Loader.doList(Loader.java:2233) ... 259 more 10:41:29,794 SEVERE [lifecycle] JSF1054: (Phase ID: RENDER_RESPONSE 6, View ID: /subViews/surveysList.xhtml) Exception thrown during phase execution: javax.faces.event.PhaseEvent[source=com.sun.faces.lifecycle.LifecycleImpl@1c7728e] I am new to using SqlResultMapping annotation.
