Hello again,
Finally I managed to get it working!
I had to remove [year] braces from the second argument - year. The
reason I used [] was the posts we exchanged recently (7th of November)
about CGI script where it was recommended by Kent that I put [] around
string argument:
Quote
The second argument to execute() is a *sequence* of parameter values.
A string is a sequence of characters, so by passing a plain string you
are saying that each character of the string is a parameter to the
SQL.
Try adding braces around the parameter to make list:
cur.execute("insert into test (name) values (?)", [sPath])
Kent
Unquote
Now the year argument is string so I thought I should do the same
again but it is not working.
The reason is of course is that I am new to python and there are so
many things to learn so the question really is why in this case there
were no [] or () necessary?
Thanks in advance
Aivars
