From the cx_Oracle documentation (section 3) [1];
"""
execute(statement, [parameters], **keywordParameters)
Execute a statement against the database. Parameters may be passed as
a dictionary or sequence or as keyword arguments. If the arguments are a
dictionary, the values will be bound by name and if the arguments are a
sequence the values will be bound by position."
"""
From the DB-API specification [2];
"""
paramstyle
String constant stating the type of parameter marker
formatting expected by the interface. Possible values are
[2]:
'qmark' Question mark style,
e.g. '...WHERE name=?'
'numeric' Numeric, positional style,
e.g. '...WHERE name=:1'
'named' Named style,
e.g. '...WHERE name=:name'
'format' AN! SI C printf format codes,
e.g. '...WHERE name=%s'
'pyformat' Python extended format codes,
e.g. '...WHERE name=%(name)s'
"""
cx_Oracle uses the 'named' parameter style, your code uses the qmark
style. To find out which style is applicable check the paramstyle
attribute of your connection object. e.g.;
>>> import cx_Oracle
>>> myConnection = cx_Oracle.connect('andy47/[EMAIL PROTECTED]')
>>> myConnection.paramstyle
'named'
