Question

I am creating a new table in a database called ‘production’ by joining data from two tables in another database called ‘crawler’. I create this new table with the following SQL query ( this query works perfectly ):

CREATE TABLE files_and_metas_joined
SELECT
    crawler.files.id,
    crawler.files.company_id,
    crawler.file_metas.title,
    crawler.file_metas.h1_tags
FROM
    crawler.files,
    crawler.file_metas
WHERE
    crawler.files.id = crawler.file_metas.file_id
    AND
    crawler.files.processed = 1
    AND
    crawler.files.junk = 0

I’d like to also add the following indexes to this table but can’t seem to figure out how to do it in the same SQL query.

PRIMARY KEY (`id`),
KEY `company_id` (`company_id`),
KEY `title` (`title`),
KEY `h1_tags` (`h1_tags`)

Can this be done in the same query used to create the table? If not, how do I add these indexes with a query afterwards?

You can do it in the same statement, they just have to go before the SELECT:

CREATE TABLE files_and_metas_joined
(
  PRIMARY KEY (`id`),
  KEY `company_id` (`company_id`),
  KEY `title` (`title`),
  KEY `h1_tags` (`h1_tags`)
)
SELECT
    crawler.files.id,
    crawler.files.company_id,
    crawler.file_metas.title,
    crawler.file_metas.h1_tags
FROM
    crawler.files,
    crawler.file_metas
WHERE
    crawler.files.id = crawler.file_metas.file_id
    AND
    crawler.files.processed = 1
    AND
    crawler.files.junk = 0
