How to insert new edges into an already existing db?

[frank....@gmail.com]

Hi,

I'm experiencing something strange when passing from ->create mode of the db to ->open mode of the db..

/QuestionMark$ ls -a

.  ..  CGraph.cpp  sparksee.cfg

Database *db = sparksee->Create(L"CGraph.gdb", L"CGraph");

  std::array<std::string, 3> FrankArray = {"FatherOf", "Spouse", "BrotherOf"};

  std::wstring RelationshipType( FrankArray[0].begin(), FrankArray[0].end() );

time ./CGraph

CNODE has to be created from scratch

RelationshipType= FatherOf

relTypeId= 0

FatherOf HAS TO BE INSERTED in DB

I switch to the open mode:

Database *db = sparksee->Open(L"CGraph.gdb", L"CGraph");

but with the same edge type

time ./CGraph

CNODE already present

RelationshipType= FatherOf

relTypeId= 9

FatherOf already present

Bu when still in open mode but with a new edge to insert:

  std::array<std::string, 3> FrankArray = {"FatherOf", "Spouse", "BrotherOf"};

  std::wstring RelationshipType( FrankArray[1].begin(), FrankArray[1].end() );

I have a crash:

time ./CGraph

CNODE already present

RelationshipType= Spouse

relTypeId= 0

Spouse HAS TO BE INSERTED in DB

So...

what to do in order to be able to insert new edges into an already existing DB?

Attached the file used.

Looking forward to hearing from you for this important matter.

Hi,

The problem may be the second argument used in the Open operation:

Database *db = sparksee->Open(L"CGraph.gdb", L"CGraph");

The second argument in the Open method is not the alias. It's a boolean value set to true only when you want to open the database in read only mode:

Database *db = sparksee->Open(L"CGraph.gdb", false);

Best regards
