Problem

The menu point „Set Composite Diagram“ allows to create a clickable link to another diagram from objects. Unfortunetly to get the references in SQL (with start and end GUID) is a little bit tricky…

Approach

Open the .eap (MDB Plus) file or der SQL Server structure (MS SQL Server Studio Express) in a tool that allows you to test SQL Statements

Solution

Composite Diagrams of Activities

i.e. for the .eap-File (Access):
To get the activities Composite diagrams, you need to join the t_object.PData1 Columne with the t_diagram.Diagram_ID Column. This can be done in the following way:

SELECT compobjects.ea_guid As src_guid,
       compobjects.name As src_name,
       b.ea_guid As dest_guid,
       b.name As dest_name 
FROM 
(
      SELECT ea_guid, 
             Name, 
             Object_Type, 
             Stereotype, 
             PData1 
      FROM t_object 
      WHERE NType=8 AND PData1 IS NOT null AND isnumeric(PData1)) compobjects
INNER JOIN t_diagram b ON b.Diagram_ID=CInt(compobjects.PData1)

Composite Diagrams of Classes

SELECT Client As src_guid, 
       obj.name As src_name, 
       Supplier As dest_guid, 
       obj2.name As dest_name   
FROM ( t_xref xr
LEFT JOIN t_object obj ON xr.Client=obj.ea_guid)
LEFT JOIN t_diagram obj2 ON xr.Supplier=obj2.ea_guid 
WHERE Supplier<>'<none>'

All Composites by source guid

SELECT src_guid,
       src_name,
       dest_guid,
       dest_name
FROM       
(
	SELECT compobjects.ea_guid As src_guid,
		   compobjects.name As src_name,
		   b.ea_guid As dest_guid,
		   b.name As dest_name 
	FROM
	(
		  SELECT ea_guid, 
				 Name, 
				 Object_Type, 
				 Stereotype, 
				 PData1 
		  FROM t_object 
		  WHERE NType=8 AND PData1 IS NOT null AND isnumeric(PData1)) compobjects
	INNER JOIN t_diagram b ON b.Diagram_ID=CInt(compobjects.PData1)
	UNION ALL 
	SELECT Client As src_guid, 
		   obj.name As src_name, 
		   Supplier As dest_guid, 
		   obj2.name As dest_name   
	FROM ( t_xref xr
	LEFT JOIN t_object obj ON xr.Client=obj.ea_guid)
	LEFT JOIN t_diagram obj2 ON xr.Supplier=obj2.ea_guid 
	WHERE Supplier<>'<none>'
)
WHERE src_guid='Put your GUID here'
