Ah, you mean a "prepared statement" object. This topic comes up from time to
time, but there are at least two DB-API implementations (InformixDB and either
mxODBC or cxOracle, or maybe both) that allow prepared statements without the
clutter of a Query object: The cursor object *is* the query object, in essence.
For example, in InformixDB you can write:
conn = informixdb.connect("test")
cur = conn.cursor()
cur.prepare("select * from customer where cust_num = ?")
# later...
cur.execute(cur.command, (1,) )
Instead of cur.command, InformixDB also allows passing None as the statement,
which makes for shorter code if the cursor has a long name, which it might,
since the cursor is being used like a prepared statement, so its name should
reflect what it does.
