更新 SQL 表将 varchar 转换为 int

Question

I currently have a table new_funeralhomes as below, which has the new data i wish to add to another table:

,

Within that table, i can easily send address,postal,phone, website and email to this table addressTest :

.

However as you can see by the new_funeralhomes table, the city/state are text value and in the second table ( addressTest ) they are int values connecting to these tables:

city :

,

province :

.

How would i go about updating the addressTest table with the new city and province? The iid and id values match up and are the same throughout.

Im newer to this so any help would be appreciated, thank you.

Answer 1

You seem to be looking for an insert... select statement with join s. The logic is:

insert into addressTest
    (address, province, postcalcode, city, primaryphone, secondaryphoe, website)
select
    n.address
    p.id,
    n.postcal,
    c.id,
    n.phone,
    n.phone2,
    n.website
from new_funeralhomes n
inner join city c on c.name = n.city
inner join province p on p.name = n.state

Side note: it seems like the source table has less columns than the target; I adapted the column list for what seem to be the matching columns - you might need to review that so it properly matches your requirement (but the join logic, which is the heart of your question, stays the same).
