[DB-SIG] RE: oracle and python

[Greg Stein (Exchange)]

You accidentally clipped the line that said: foo = [ 47 ]

(i.e. it was a sequence)

I make this mistake all the time!

The 2nd argument to execute() has to be a sequence, i.e. a tuple or
list. 
That's why it can't bind the variables.  Of course, it would be even
better if the oracledb module itself checked and returned a somewhat
more
useful error message :-) 

You want:

cur.execute("begin testprocs.t1(:1) ; end ; ",  [foo] )

The other variation on this which always catches me is that you can't
just do 
"(foo)" to turn it into a tuple.  You need to do "(foo,)".  This is way
ugly, so I just do "[foo]".
