[cx-oracle-users] binding datetime in query

[Rizzuto, R. <Ray...@si...>]

I am issuing a query to our database, with a where clause that is comparing a Date column to a parameter.  The parameter is bound to a datetime object.  I am using version 5.02.  Will the datetime object be sent as a native Oracle date type, or will it be sent as a string?  If the latter, what format would it be in?

The reason I ask is that the DBA's think the query is not performing well, and there is concern that the optimizer is not using the index on the date column due to the way I am passing in the date.

The date parameter is being passed via a dictionary, like so:

params["p_order_date"] = orderDate.datetime()  # returns a datetime type from a custom class
.
.
cursor.execute(query, params)

The query string passed to execute is built dynamically, and executed once.
