Populating database table column with corresponding values from another table in PostgreSQL

Question

Table 1 is \'z_scrapestorm_rentals\' and table 2 is \'pcpao_cols\'. They both have address columns named \'address_1_line_trunc\' and \'address_one_line\' respectively.

Answer 1

Okay, so I answered my own question and inserted the web_strap values from the other table into the target table by using the following query:

UPDATE z_scrapestorm_rentals
    SET web_strap = pcpao_cols.web_strap
    FROM
        pcpao_cols
    WHERE Z_scrapestorm_rentals.address_1_line_trunc 
ILIKE pcpao_cols.address_one_line
    RETURNING pcpao_cols.web_strap;

What was missing from my original query I detailed in my question's "method 1" was the RETURNING keyword.
