Title: SQL search relations between nested objects with conveyed item
Post by: Thorn on November 09, 2019, 01:32:59 am

Hi,

I have a Component diagram. There are Components with Ports connected by Information Flow. Information Flow has Items conveyed.
I need to create list of all relationships within the diagram (to generate integration catalog out of the diagram). As all the Components are placed in one Package as a reusable assets, I need to filter the search on the level of diagram, or maybe specific Tagged Value

I have tried following search (TOP 50 is used only for debug because many objects are within the database):

Code: [Select]

SELECT TOP 50
  PRODUCER.Stereotype AS Producer_Type,
      PRODUCER.Name AS Producer_Name,
  CONSUMER.Stereotype AS Consumer_Type,
      CONSUMER.Name AS Consumer_Name,
  CONNECTOR.Name AS Purpose,
      CONNECTOR.Stereotype AS Connector_Type,
      CONVEYED.Stereotype AS Conveyed_Type,
      CONVEYED.Name AS Data_Entity,
      PACKAGE.Name AS Package,
  DIAGRAM.Name AS Diagram,
  TAGS.Property AS Tag_Name,
  TAGS.VALUE AS Tag_Value
FROM t_xref XCONVEYED, t_object CONVEYED,
      t_object PRODUCER, t_object CONSUMER,
      t_connector CONNECTOR, t_object PACKAGE,
  t_diagram DIAGRAM, t_objectproperties TAGS
WHERE XCONVEYED.Behavior='conveyed'
      AND XCONVEYED.Description LIKE '%' + CONVEYED.ea_guid + '%'
      AND CONNECTOR.Start_Object_ID=PRODUCER.Object_ID
      AND CONNECTOR.End_Object_ID=CONSUMER.Object_ID
      AND CONNECTOR.ea_guid = XCONVEYED.Client
  AND DIAGRAM.Name = 'Relations search'

but this will select only direct relations between ports without superior Component. And even the filtering doesn't work

any idea?

Not going to try to understand the SQL. For me, when SQL simply get's too weird, writing a script works best where I use a rather simple but performant SQL and using the script to re-work the result with the tricky parts.

I wrote a query for conveyed items on connectors between ports a while ago.
I don't remember the details right now, but it might be helpful.
I think for complex queries you should really use the join syntax to keep thing a bit sane.

Code: [Select]

select
ost.[Name] as Source,
c.[Name] as ConnectorName, ose.[Name] as Target,io.Name as Conveyed, #DB=JET#IIF(io.Stereotype is null, null, '«' + io.Stereotype + '»')#DB=JET#
#DB=Other#CASE when io.Stereotype is not null THEN '«' + io.Stereotype + '»' ELSE null END #DB=Other#
as ConveyedStereo
from (((((((((t_diagram d
inner join [t_diagramlinks] dl on dl.[DiagramID] = d.[Diagram_ID])
inner join [t_connector] c on dl.[ConnectorID] = c.[Connector_ID])
inner join [t_object] ost on ( ost.[Object_ID] = c.[Start_Object_ID]
                                          and ost.[Object_Type] = 'Port'))
inner join [t_object] ose on ( ose.[Object_ID] = c.[End_Object_ID]
                                            and ose.[Object_Type] = 'Port'))
inner join [t_diagramObjects] dob on dob.[Diagram_ID] = d.[Diagram_ID])
left join t_xref x on (x.[Client] = c.ea_guid
                      and x.[Behavior] = 'abstraction'))
left join t_connector ci on left(x.description, 255) like '#WC#' + ci.[ea_guid] + '#WC#')
left join t_xref xi on (xi.[Client] = ci.[ea_guid]
                              and xi.[Behavior] = 'conveyed'))
left join t_object io on left(xi.[Description],255) like  '#WC#' + io.[ea_guid] + '#WC#')                                                                                       
where d.[Diagram_ID] = #DIAGRAMID#
and dob.[Object_ID] = c.[Start_Object_ID]
and c.[Connector_Type] = 'Connector'
and dl.[Hidden] = 0
order by connectorName asc
