Find all relations of a certain field using tableId and fieldId

Posted on by Community Member

Hi

I would like some help to create a loop that finds all related table relations (which are 2 in this case) using a tableId and a FieldId.
I have an issue that my code only finds the first relation instead of both relations 

As an example:
MainTable has field A with 2 relations:

Relation 1 MainTable.A = FirstRelation.A && MainTable.B = 2 
Relation 2 MainTable.A = SecondRelation.A && MainTable.B = 1 


So my code only finds FirstRelation and retuns the tableId of table  FirstRelation eg. tabelId = 16402

Could some one help me to write a Job that uses a tableId and fieldId that loops all the relations of this fieldId
 

Loop should be in the if statement.

static void findAllTableRelations(Args _args)
{
TableId                 _tableId;
FieldId                 _fieldId;
SysDictField            sysDictField;    
SysDictRelation         sysDictRelation; 

//real values of the table- and fieldId
_tableId                = 124670; //MainTable
_fieldId                = 60136; //field A

sysDictField            = new SysDictField(_tableId, _fieldId);
sysDictRelation         = new SysDictRelation(_tableId);


if (sysDictRelation)
{
        //this should be some kind of loop so that both related tables are found
        refTableId      = sysDictRelation.loadFieldRelation(sysDictField.id(), TableScope::IncludeBaseTables); 
        
        breakpoint;
}
}

Thanks in advance
Tomas

    This is how we can loop through all the fields of a table in X++ , you have to modify this to use SysDictRelation class  to find out all the relations.

    static void Job1(Args _args)

    {

       SysDictTable    dictTable = new SysDictTable(tableNum(PurchLine));

       SysDictField    dictField;

       TreeNode        treeNode;

       FieldId         fieldId = dictTable.fieldNext(0);

       while (fieldId)

       {

           dictField = dictTable.fieldObject(fieldId);

           if (dictField.isSql() && !dictField.isSystem())

           {

               treeNode = dictField.treeNode();

               info(strFmt("%1 | %2 | %3",

                   dictField.name(),                                               // Field name

                   treeNode.AOTgetProperty("Label"),                               // Label id

                   SysLabel::labelId2String(treeNode.AOTgetProperty("Label"))));   // Label string

           }

           fieldId = dictTable.fieldNext(fieldId);

       }

    Hi Sergeant,

    I don't know if you have solved it, I found your question and I was looking for something similar.

    Maybe this can help, use the relations method and then get all the sysDictRelation.

    static void findAllTableRelations(Args _args)
    {
     int relationLine, allRelationInTable;
     TableId _tableId;
     FieldId _fieldId;

     SysDictTable sysDictTable;
     SysDictRelation sysDictRelation;

     Set tableRelationSet, result;
     SetEnumerator tableRelationSetEnumerator;

     _tableId = 124670;
     _fieldId = 60136;

     sysDictTable = new SysDictTable(_tableId);
     result = new Set(Types::Class);

     tableRelationSet = sysDictTable.relations();
     tableRelationSetEnumerator = tableRelationSet.getEnumerator();

     while( tableRelationSetEnumerator.moveNext() )
     {
       sysDictRelation = tableRelationSetEnumerator.current();
       allRelationInTable = sysDictRelation.lines();

       for ( relationLine = 1; relationLine <= allRelationInTable; relationLine ++ )
       {
         if( _fieldId == sysDictRelation.lineTableValue(relationLine))
         {
           result.add(sysDictRelation);
         }
       }
     }
    }

    hope this will help :)
