Question

I have a MySQL insert query which needs to pull one data field from another table and I was wondering if this can be done with a select subquery

INSERT INTO resources
(
     client_account_id,
     date_time,
     resource_name,
     resource_description_id,
)
VALUES
(
      {0},
      '{1}',
      '{2}',
      {3},
 )

and I need a select query to get the resource_description_id from another table

SELECT resource_description_id 
FROM resource_descriptions 
WHERE resource_description = '{0}'

I have seen examples for duplicating entire tables, but I’m not sure how this can be done when just one field is needed from another table and the other fields come from a form.

Thanks!

Your subquery can just SELECT the values it needs. Something like:

INSERT INTO resources
(
     client_account_id,
     date_time,
     resource_name,
     resource_description_id,
)
SELECT {0}, '{1}','{2}', resource_description_id 
FROM resource_descriptions 
WHERE resource_description = '{3}'
