Hi I have a problem with HQL, the date function is not working, it is throwing the exception below: I'm using a simple query to get only the date from the DateTime field: select date(t.Data) from Trajtimi t where t.Pacienti.ID = 3
I'm using "NHibernate.Dialect.MsSql2000Dialect" I've tried with MsSql2008Dialect and also MsSql2005Dialect it's the same. I've looked also at source of "NHibernate.Dialect.MsSql2000Dialect" https://nhcontrib.svn.sourceforge.net/svnroot/nhibernate/trunk/nhibernate/src/NHibernate/Dialect/MsSql2000Dialect.cs I saw there the line, RegisterFunction("date", new SQLFunctionTemplate(NHibernateUtil.Date, "dateadd(dd, 0, datediff(dd, 0, ?1))")); I think the date function is implemented I tried the funcion in sql management studio "dateadd(dd, 0, datediff(dd, 0, someDateTime))" and it is striping the time very well, but Nhibernate its not, at least for me. I don't know where I'm wrong, if you could guide me... P.S. The same thing in SQLite is working perfect. Visar NHibernate.QueryException was unhandled Message="No data type for node: MethodNode ( ( date ( exprList ( trajtimi0_.Data trajtimi0_.ID Data ) ) ) [select date(t.Data) as dteRegj from Entities.Trajtimi t where t.Pacienti.ID = 3]" Source="NHibernate" QueryString="select date(t.Data) from Entities.Trajtimi t where t.Pacienti.ID = 3" StackTrace: at NHibernate.Hql.Ast.ANTLR.Tree.SelectClause.InitializeExplicitSelectClause(FromClause fromClause) at NHibernate.Hql.Ast.ANTLR.HqlSqlWalker.UseSelectClause(IASTNode select) at NHibernate.Hql.Ast.ANTLR.HqlSqlWalker.ProcessQuery(IASTNode select, IASTNode query) at NHibernate.Hql.Ast.ANTLR.HqlSqlWalker.unionedQuery() at NHibernate.Hql.Ast.ANTLR.HqlSqlWalker.query() at NHibernate.Hql.Ast.ANTLR.HqlSqlWalker.selectStatement() at NHibernate.Hql.Ast.ANTLR.HqlSqlWalker.statement() at NHibernate.Hql.Ast.ANTLR.HqlSqlTranslator.Translate() at NHibernate.Hql.Ast.ANTLR.QueryTranslatorImpl.Analyze(HqlParseEngine parser, String collectionRole) at NHibernate.Hql.Ast.ANTLR.QueryTranslatorImpl.DoCompile(IDictionary`2 replacements, Boolean shallow, String collectionRole) at NHibernate.Hql.Ast.ANTLR.QueryTranslatorImpl.Compile(IDictionary`2 replacements, Boolean shallow) at NHibernate.Engine.Query.HQLQueryPlan..ctor(String hql, String collectionRole, Boolean shallow, IDictionary`2 enabledFilters, ISessionFactoryImplementor factory) at NHibernate.Engine.Query.HQLQueryPlan..ctor(String hql, Boolean shallow, IDictionary`2 enabledFilters, ISessionFactoryImplementor factory) at NHibernate.Engine.Query.QueryPlanCache.GetHQLQueryPlan(String queryString, Boolean shallow, IDictionary`2 enabledFilters) at NHibernate.Impl.AbstractSessionImpl.GetHQLQueryPlan(String query, Boolean shallow) at NHibernate.Impl.AbstractSessionImpl.CreateQuery(String queryString) -- You received this message because you are subscribed to the Google Groups "nhusers" group.
