Exception executing query when ibm_db_dbi.paramstyle = 'format'

Queries can not be formatted using 'format' paramstyle

>>> import ibm_db_dbi
>>> ibm_db_dbi.paramstyle
'qmark'
>>> ibm_db_dbi.paramstyle = 'format'
>>> conn = ibm_db_dbi.connect("db2")
>>> cursor=conn.cursor()
>>> q = 'SELECT col1,col2 FROM test WHERE col0 = %s'
>>> cursor.execute(q, (1819043,))

The above exception is expected one since it is not supported.

currently ibm_db_dbi only supports qmark parameter style.

Thanks for the answer. The module could issue a warning 'not
implemented' in case it's set to something different than 'qmark' and
it should be documented in the code and the README file.

Code
=====
# Module globals
apilevel = '2.0'
threadsafety = 0
# only qmark is currently supported
paramstyle = 'qmark'
