In the http://www.mongodb.org/display/DOCS/Collections
Collection names should begin with letters or an underscore and may include numbers; $ is reserved.
Use $ in name:
> db.dropDatabase() > db.createCollection("$test") { "ok" : 1 } > db.getCollectionNames() [ "system.indexes"] > db.createCollection("$test") { "errmsg" : "collection already exists", "ok" : 0 }
Use UTF-8 characters when creating collection:
> db.getCollectionNames() [ "system.indexes" ] > db.createCollection("имя") { "errmsg" : "exception: invalid ns: query-test.имя.$_id_", "code" : 10094, "ok" : 0 } > db.getCollectionNames() [ "system.indexes", "имя" ]
Use UTF-8 characters when renaming collection:
> db.dropDatabase()
{ "dropped" : "query-test", "ok" : 1 }
> db.createCollection("tmp")
{ "ok" : 1 }
> db.tmp.renameCollection("имя")
{ "ok" : 1 }
> db.getCollectionNames()
[ "system.indexes", "имя" ]
Inserting into collection with name in UTF-8:
> db.ИМЯ.insert({"test":1})
invalid ns: query-test.ИМЯ
> db["ИМЯ"].insert({"test":1})
invalid ns: query-test.ИМЯ
Dropping collection with name in UTF-8:
> db.ИМЯ.drop() false > db.getCollectionNames() [ "system.indexes", "имя" ]
In Java, Python and PHP it is impossible to create collection with name in UTF-8, but it's possible to use such characters in rename and drop.
