Source:  (, )
Nature: Clarification
Severity: Minor
Summary: top relation AssocToFKey { pKey : Key; ... when { ...; pKey = destTbl.key; } ... } In my opinion that doesn't work. pKey is of type Key, destTbl.key is of type OrderedSet key, isn't it ?

Resolution: Section: A1.1.1

top relation AssocToFKey { pKey : Key; ... when{ ...; pKey = destTbl.key; }

... } In my opinion that doesn't work. pKey is of type Key, destTbl.key is of type OrderedSet key, isn't it ?

Discussion

Yes. Well at least it's a Collection; the diagram leaves an ambiguity.

Comparison with the QVTc solution shows that the 'primary' key should be selected, and initialized on creation.

Loading the example in the Eclipse QVTr editor reveals many more problems.
Revised Text: In A.1.1.1

Replace all usage of "//" by "--"

Replace

key Table (name, schema);
key Column (name, owner);
key Key (name, owner);

by

key Table {name, schema};
key Column {name, owner};
key Key {name, owner};

Replace

key=k:Key {name=cn+'_pk', column=cl}};

by

_'key'=k:Key {name=cn+'_pk', column=cl, kind='primary'}};

Replace

srcTbl, destTbl: Table;
pKey: Key;

by

srcTbl, destTbl: SimpleRDBMS::Table;
pKey: SimpleRDBMS::Key;

Replace

pKey = destTbl.key;

by

pKey = destTbl._'key'->select(kind='primary');

Replace

function PrimitiveTypeToSqlType(primitiveTpe:String):String

by

query PrimitiveTypeToSqlType(primitiveType:String):String

Replace

endif;

Discussion: 
I think that the intention is for pKey to 'loop' over each destTbl.key, but I cannot see text to justify this.
Collection matching needs revision, in particular the untenable prohibition on nested collections.
