Say I want to insert a comment, the comments table needs a customer_id
but I only have email
. I do not want to select the customer in a separate query beforehand.
The INSERT INTO ... SELECT
query from orm/query-builder.html#inserting-data looks like what I want exactly.
But how do I provide values outside of what gets selected in the first part of the query?
I tried:
$select = $customersTable->find()
->select(['customer_id'])
->where(['email' => 'username@example.com']);
$query = $this->query()
->insert(['customer_id', 'data'])
->values($select)
->values(['data' => 'test 123'])
->execute();
I got: You cannot mix subqueries and array data in inserts
I tried:
$select = $customersTable->find()
->select(['customer_id', '"test" AS `data`'])
->where(['email' => 'username@example']);
$query = $this->query()
->insert(['customer_id', 'data'])
->values($select)
->execute();
I got:
Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '`` AS `Customers__"test" AS `data`` FROM `customer` `Customers` ' at line 1
INSERT INTO `comments` (`customer_id`, `data`) SELECT `Customers`.`customer_id` AS `Customers__customer_id`, `Customers."test" AS `data`` AS `Customers__"test" AS `data`` FROM `customer` `Customers` WHERE `email` = :c0
Please help
Custom aliased fields in the SELECT
clause can be defined via the regular key => value
array syntax, where the key will be used as the alias.
Also make sure to let the driver quote the data, as it will be inserted as-is, and thus would otherwise be prone to possible SQL injections!
$select = $customersTable->find()
->select([
'customer_id',
'data' => $customersTable->getConnection()->quote('test')
])
->where(['email' => 'username@example']);
