inserting integer in Table

[Thomas SMETS]

Well Roland,

didn't work at my place ...
I reCREATED a similar table with  a column defined as int4 & bearing the
name pk.
<snip>
tsmets=> create table TESTPYTHON
tsmets-> ( pk integer, filename varchar(99), file bytea );     
</snip>

I couldn't insert a simple integer with you command :
        i = 0
        conn.query("insert into TESTPYTHON pk values ( %s );" % i)


Exception thrown is :
<snip>
Traceback (innermost last):
  File "insertBlobs.py", line 15, in ?
    conn.query("insert into TESTPYTHON (pk) values ( %s );" % i)
pg.error: ERROR:  Relation 'testpython' does not have attribute 'pk'    
</snip>

Shouldn't I use %i or something like that instead of %s ?

Tx,

Thomas,
