sql server - Cascade delete in Eclipselink in a self-referencing table -


i'm trying cascade delete in jpa self-referencing table whatever same error.

@entity @table(name="sys_acl", schema="dbo") public class acl implements serializable { private static final long serialversionuid = 1l; @embeddedid protected accesscontrollistpk accesscontrollistpk; @joincolumn(name = "role_id", referencedcolumnname = "id", nullable = false, insertable = false, updatable = false) @manytoone(optional = false) private roletable roletable; @joincolumn(name = "view_id", referencedcolumnname = "id", nullable = false, insertable = false, updatable = false) @manytoone(optional = false) private pagemap pagemap; @column(name="parent_role") private long parentrole; @column(name="parent_view_id") private long parentview; @joincolumns({ @joincolumn(name = "parent_role", referencedcolumnname = "role_id", nullable = true, insertable = false, updatable = false), @joincolumn(name = "parent_view_id", referencedcolumnname = "view_id", nullable = true, insertable = false, updatable = false)}) @onetomany(cascade = cascadetype.all, orphanremoval=true) @privateowned private list<acl> children = new linkedlist<acl>();

this error i'm getting:

exception [eclipselink-4002] (eclipse persistence services - 2.3.0.v20110604-r9504): org.eclipse.persistence.exceptions.databaseexception internal exception: com.microsoft.sqlserver.jdbc.sqlserverexception: delete statement conflicted same table reference constraint "sysccsscntrllstprntvwd". conflict occurred in database "mydb", table "dbo.sys_acl" error code: 547

the database structure this:

create table sys_acl ( view_id numeric, role_id numeric, parent_role numeric, parent_view_id numeric, constraint pk primary key (role_id, view_id), constraint fk1 foriegn key (view_id) referencing view_table(id), constraint fk2 foriegn key (role_id) referenicng role_table(id), constraint fkself foreign key (parent_role, parent_view) referencing sys_acl(role_id, view_id));

i can use recursive method delete children first want know if possible doing in jpa. i'm using gf 3.1, , eclipselink 2.3.0

what sql log?

your model seems overly complex. might want remove accesscontrollistpk , put @id on @manytoones.

your issue may cause because using @joincolumn on @onetomany, use mappedby , @manytoone inverse, seem use @basuc foreign keys instead, remove these , join column on onetomany , define @manytoone parent.

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
