Hello, I am reposting this question since I never got a reply to it. Hopefully someone who has worked on another driver or OrientDB internals can give a quick response.
I am continuing work on a Go (golang) driver using the network binary protocol. I currently have *parameterized* SQL queries and commands working, such as "select from Cat where name = ?", which I send using the REQUEST_COMMAND (41) database operation type. What is unclear to me is whether I need to do anything from the driver side to "prepare" the statement - besides serializing it as an EMBEDDEDMAP with the key "params" - I have that part working. Beyond that, is there is call to the OrientDB server that will *prepare* (optimize and cache) the query or command on the server side? I walked through the Java client code with a debugger that does parameterized queries and I didn't see any special handling besides serializing the params as an EMBEDDEDMAP. In some databases, the typical flow is that the client sends a SQL statement with placeholders to the server for preparation, the server responds with a statement ID, and then the client executes the statement by sending its ID and parameters. Is there anything like that in OrientDB? Thanks for your help, Michael -- --- You received this message because you are subscribed to the Google Groups "OrientDB" group.
