java - PostgreSQL and Hibernate JPA not working -

-

i'm trying use jpa in wildfly (which uses hibernate) postgresql. turned on hibernate.show_sql can execute same query in pgadmin iii. query 1 (edit: issuemanager_sch schema. without in pgadmin query fails "relation not exist" error):

select issuetypet0_.id_issue_type id_issue1_3_, issuetypet0_.name name2_3_ issuemanager_sch.issue_type issuetypet0_

when executed hibernate showed in both postgresql log , wildfly log : 

relation "issuemanager_sch.issue_type" not exist character 87

however, when copy (to grant i'm executing exact same query), paste , run query in pgadmin iii it's executed , results.

what possibly wrong configurations? (i tried both quoted , unquoted queries , results same: fails hibernate, works in pgadmin iii)

persistence.xml

edit: issue_type table:

create table issuemanager_sch.issue_type (   id_issue_type bigint not null default nextval('issuemanager_sch.issue_type_seq'::regclass),   name text not null,   constraint "pk_issue_type" primary key (id_issue_type) )

edit: issuetypeto mapping:

@entity @table(name = "issue_type") public class issuetypeto implements serializable{      @id     @column(name = "id_issue_type")     @generatedvalue(strategy = generationtype.sequence, generator = "issue_type_seq")     @sequencegenerator(name = "issue_type_seq", sequencename = "issue_type_seq", allocationsize = 1)     private long idissuetype;      @column(name = "name", length = 45)     private string name;      // getters , setters }

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
