Thanks! WIll have to check it out.

Glad it worked out. Hopefully they update it soon. We are just using the
queries. The only suggestion is to watch for the parameters. First, adding
parameters was not documented well. Anyone looking to add them, you have to
use:
db.command(query, {'params':{}}, callback);
Then you can either use the object or array types described on the OrientDB
site. Now the problems come in on the parsing of those params. There is
some inconsistency and bugs on OrientDB side... RecordID formats differ
between SELECT, INSERT, and UPDATE. Some throw an error with quotes around
the RecordID, some don't. OrientDB has not yet implemented parameters in
sub-queries. This is very bad since it is heavily used. Since we are to
check and parse our own parameters for sub-queries, it would be nice for
the node-orientdb module to just insert the params for us and send it off
to the database.
I did find one solution that you might want to also modify in the
node-orientdb files... In the file,
"/orientdb/lib/orientdb/connection/parser.js", around line 320, comment out
the four lines below:
//if(REGEXP_RID.test(value)) {
// result = result.concat(value);
//} else {
//***Leave the following line***
result = result.concat(...
//}
Seems to fix some of the RecordID parameter problems. Before the change,
the RecordID would not be quoted and would corrupt the object being sent to
the db if the RID property was at the beginning of an object. For example:
{'rid':#10:1, 'name':'Java'}
Notice the uncommented RID has an exposed ":" that throws off the object.
