psycopg2: Update multiple rows in a table with values from a tuple of tuples

Question

I\'m attempting to update several rows at once using a tuple of tuples. I figured out how to construct the sql statement from this post, but implementing it in psycopg2

Answer 1

This post pointed me in the right direction. The documentation for extras.execute_values also contains a great example using the UPDATE clause.

c = db.cursor()
update_query = """UPDATE my_table AS t 
                  SET name = e.name 
                  FROM (VALUES %s) AS e(name, id) 
                  WHERE e.id = t.id;"""

psycopg2.extras.execute_values (
    c, update_query, new_values, template=None, page_size=100
)
