RE: Error when doing sql

Cravan,
I am not new to SQL, but new to Postgres and python scripting. I suspect somewhere in your python script there is still a reference to “title” instead “Title”, and you might want to search for that. I have been working with PgAdmin, but not worked with psql or python yet.
Hope someone can help you troubleshoot the problem.

Thank you,

Aruna Gubba

Hi Aruna,
                I have done what you suggested, and got a similar error with a “hint” this time

Cravan,
Postgres is case-sensitive, and the columns names in your insert statement should exactly match the table definition.
Your insert into statement should look like this, (surround the exact column name around double quotes)
Insert into movies(“Title”,”Year”, “Runtime”,”imdbID”, “imdbRating”)

Thank you,

Aruna Gubba
