Sorry, accidentally pressed send.


cur_p = conn_pr(cursor_factory=psycopg2.extras.DictCursor)

cur_t.execute("""
                 SELECT TRANSLATE(snumber, ' ', '')
                 FROM sprofile """)

DictCursor is a hybrid dict/sequence.

# This will result in KeyError
for row in cur_t:
print row['snumber']

Above you are using it as a dict and as David pointed you would need to use translate as the key:

test=> select translate('test', '', '');
 translate
-----------
 test

# This works fine
for row in cur_t:
print row[0]

Above you are using as a sequence, so the indexing works.

Sorry again.

I would really appreciate any suggestions.

Thanks,
