问题 I have an oracle package with a procedure that has a in out reference cursor. My understanding is that this is pretty standard. What I didn't like is the fact that I had to write a ton of code to just see the output. So I asked this question and it turns out I can get what I want by creating a function that wraps the procedure. Update: Looks like I don't need the function anymore but it may be worth knowing anyway for those curious see the original question and answer updates. Here's the

问题 I need help understanding if the way I'm trying to use a Ref Cursor as a ReturnValue Parameter for multiple records/values, with the PL/SQL just being the CommandText of an OracleCommand object and not in a Stored Procedure or Function, is even possible. If that is not possible, what I'm trying to do is find a way to issue a PL/SQL statement that will Update an unknown number of records (depends on how many match the WHERE clause), and return the Ids of all the records Updated in an

问题 We have a system that uses an Oracle database. I've been asked if the system makes use of connection pooling which I'm not sure about. We are using the Oracle.DataAccess.Client.OracleConnection When reading up on the subject I've found that connection pooling is set to true in the connection string and that it is set to true by default. Our connection string does not include any pooling settings. Does this imply that we are using pooling and if so what would the default min and max pool size
