python - SQLite parameter substitution and quotes

Question

I have this line that works OK:

c.execute('select cleanseq from cleanseqs WHERE newID="%s"'%name)

But I want to use SQLite parameter substitution instead instead of string substitution (because I see here that this is safer).

This is my (failed) try:

t = (name,)
c.execute('select cleanseq from cleanseqs WHERE newID="?"',t)

But this line returns:

'Incorrect number of bindings supplied. The current statement uses 0, and there are 1 supplied.'

So the left part of my statement doesn't work. I am supplying one binding (name, in t) but seems that the question mark (?) is not being parsed. If I delete the quotes sourronding the ?, it works. But I want the quotes to remain there since I remember that there are cases where I need them.

So the question is: How do I convert this line:

c.execute('select cleanseq from cleanseqs WHERE newID="%s"'%name)

Answer 1

To anyone who like me found this thread and got really frustrated by people ignoring the fact that sometimes you can't just ignore the quotes (because you're using say a LIKE command) you can fix this by doing something to the effect of:

var = name + "%"
c.execute('SELECT foo FROM bar WHERE name LIKE ?',(var,))

This will allow you to substitute in wildcards in this situation.
