curr.pgsql.execute(''' INSERT INTO my_table(name, age) SELECT name, age WHERE NOT EXISTS(SELECT name FROM my_table WHERE name= name) ''', ('Scott', 23))
Pretty sure this would throw an exception as there are no parameter markers in the query for the parameter values in the tuple to bind to. So are you swallowing the exception in you code?
Sorry, I don't understand, where should I place the from clause? I just saw a sample code like this in SO, so I gave it a shot
Not tested: ''' INSERT INTO my_table(%(name)s, %(age)s) WHERE NOT EXISTS(SELECT name FROM my_table WHERE name= %(name)) ''', {'name': Scott', 'age': 23}) -- Adrian Klaver adrian.klaver@aklaver.com
Updated my code to this:
curr.pgsql.execute(''' INSERT INTO my_table(name, age)
SELECT %s, %s
WHERE NOT EXISTS(SELECT name FROM my_table WHERE name= name)
''', ('Scott', 23))
If I remove SELECT statement, I will get an error message: error : psycopg2.ProgrammingError: syntax error at or near "WHERE" LINE 12: WHERE NOT EXISTS
