psycopg2 : cursor already closed

Question

I am using psycopg2 2.6.1. I have a bunch of queries that I need to execute in sequence.

conn = psycopg2.connect(database=redshift_database,
                


        

Answer 1

You should explicitely regenerate the cursor in the except bloc in case something went wrong at a lower level that the query:

for query in queries:
    try:
        cursor.execute(query)
    except:
        print e.message
        try:
            cursor.close()
            cursor = conn.cursor()
        except:
            conn.close()
            conn = psycopg2.connect(...)
        cursor = conn.cursor()
