Question

I am trying to convert an excel sheet into an sqlite3 db using win32com module in python. My excel sheet has 6 columns and so my a part of my python code is:

for row in exceldata:
      c.execute('INSERT INTO exceltable1 VALUES(?,?,?,?,?,?)',row)
conn.commit()

But python gives me the following error:

c.execute('INSERT INTO exceltable VALUES(?,?,?,?,?,?)',row)
ProgrammingError: Incorrect number of bindings supplied. The current statement uses 6, and there are 5 supplied.

If I try to remove one question mark and run it again, the error now becomes:

c.execute('INSERT INTO exceltable1 VALUES(?,?,?,?,?)',row)
OperationalError: table exceltable1 has 6 columns but 5 values were supplied

Could anyone please explain to me whats happening here and if there is any solution…
Thx.

Answer 1

First of all, make sure what the value of row is, and how many items it has:

 print row, len(row)

Then try and use the complete insert sql statement:

 insert into table (col1, col2, col3, ...) values (?, ?,? ...)

and see what happens. This should solve your problem, or at least let you understand what is happening.
