Hello,
I am sure this is in the documentation somewhere, but I am stumped as to
where.
I am trying to pass in a table name to reset a series of sequences.
conn_cursor.execute("""SELECT setval(pg_get_serial_sequence("%s", %s), 1,
false);""", ( _column[0]), _column[1],))
where _column[0] is a table name, and _column[1] is a column name. So the
table name needs to be directly enclosed in double-quotes, but the psycopg2
adapter is adding single quotes inside that. So instead of getting
"table_name" I get "'table_name'" which does not work. I feel like is
probably an issue of escaping the quotes somehow but I cannot figure out
how. Psycopg2's behavior is completely correct here, it sees a string and
wraps it in quotes, but this case of wanting to access a table name is
somewhat of a special case.
Thanks so much for such a great piece of software.
