Re: ValueError: too many values to unpack

Just a quick on, try taking out the parens, I don't think you need them.

Here is how I usually do it

for schedrow in sched:
            ##print 'schedrow: ' + str(schedrow)
            sch, level, start, end, bp = schedrow

Thanks,

   My application has a table named 'model' with this schema:

CREATE TABLE model (model_name TEXT NOT NULL PRIMARY KEY,
model_desc TEXT, model_type TEXT, keName TEXT, agent INTEGER);

and it holds one record.

   During testing I created a new database and inserted values in each
of
these fields. But, when I open the existing database to read each column
and
insert the values in the appropriate GUI widgets, I get the error
message on
the subject line:

   File "/data1/eikos/modelPage.py", line 198, in OnOpenMod
     for (model_desc, model_type, keName, agent) in self.appData.cur:
ValueError: too many values to unpack

   What I'm trying to do in this method (starting at line 197) is,

     self.appData.cur.execute("select * from model")
     for (model_desc, model_type, keName, agent) in self.appData.cur:
       modDesc = model_desc
       mType = model_type
       knowlEng = keName
       method = agent
     self.tcDesc.SetValue(modDesc)
     self.modType.SetString(self.modType.SetSelection(mType))
     self.keName.SetValue(knowlEng)
     self.agent.SetSelection(method)

   My newness to pysqlite is undoubtably the reason why I have the
syntax
incorrect, and I did read the appropriate section in the on-line doc on
how
to extract each table record into a local variable. I thought the 'for
...'
loop syntax was appropriate when there's a single record, and I did not
need
to use fetchone(). What is the appropriate syntax?
