I’m trying to make a mysql query to select several tables and LEFT join

  • 0

I’m trying to make a mysql query to select several tables and LEFT join them, however they all have same columns names ‘user’ etc. I want to rename all the fields in this manner . so I tried the following query

SELECT mod_backup_accounts . * AS account . * , mod_backup_subscriptions . *
FROM `mod_backup_accounts`
LEFT JOIN `mod_backup_subscriptions` ON `mod_backup_accounts`.subscription_id = `mod_backup_subscriptions`.package_id

However the mod_backup_accounts . * AS account . * makes it fail, is there a way to do this? so it would be names as account.

    You cannot supply a shorthand to alias columns you must do it explicitly for each column name. In general anyway, it is typically recommended to name all columns explicitly in the SELECT list rather than using SELECT *, since it allows you to deterministically specify the column order, and protects you against accidentally pulling in a large BLOB later on if one ever gets added to the table ( or any other schema changes ).

    SELECT
  mod_backup_accounts.user AS account_user,
  mod_backup_subscriptions.user AS subscription_user,
  ...
  ...
FROM
  mod_backup_accounts
  LEFT JOIN `mod_backup_subscriptions` ON `mod_backup_accounts`.subscription_id = `mod_backup_subscriptions`.package_id
