how to execute update operation in couchdb in java programme

问题

In my application I am using couchdb for storage. I want to execute update operation in which the _rev value must be change. so kindly help me what i have to do in my java program.

回答1:

The code for reading, modifying and then saving a document is:

Document doc = db.getDocument("documentid1234");
doc.put("foo","bar");
db.saveDocument(doc);

The doc object will contain the _rev from when the document was read with the getDocument() call.

You don't generate the _rev value, couch does.
