Re: Error when doing sql

Hi Aruna,

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

The above exception was the direct cause of the following exception:

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”)

Hi, here is the table:

\d+ tablename
