"Efficient Querying with MYSQL XDEVAPI Through Multiple OR (II) Requests

Currently, I am utilizing the XDEVAPI and attempting to incorporate the or(||) statement in JavaScript. However, it appears to malfunction after 1 or/(||) statements have been included. I need to fetch data from the database based on 5 distinct statuses:

.select(['customer_name',
         'account_status',
                  ])
         .where('customer_name like :customer_name && account_status like :account_status || account_status like :account_status || account_status like :account_status')
         .bind('customer_name', customer_name)
         .bind('account_status', 'Some_Status_1')
         .bind('account_status','Some_Status_2')
         .bind('account_status', 'Some_Status_3')
         .execute()

Can I utilize REGEXP 'Some_Status_1'|Some_Status_2' etc?

If so, what would be the correct syntax to achieve this?

Alternatively, is there another approach that I might not be aware of?

I appreciate any guidance you can provide.

Answer №1

The issue at hand may not be directly related to the usage of OR, but rather stems from the repetition of placeholders. In CRUD style APIs, named parameters are typically employed, as outlined in detail here. When you call

bind('account_status', 'something')

multiple times, it essentially overwrites the previous value assigned to the account_status placeholder.

To achieve your desired outcome (presumably), it's necessary to utilize distinct placeholder names. For example:

.select(['customer_name', 'account_status'])
  .where('customer_name like :customer_name && account_status like :account_status1 || account_status like :account_status2 || account_status like :account_status3')
  .bind('customer_name', customer_name)
  .bind('account_status1', 'Some_Status_1')
  .bind('account_status2', 'Some_Status_2')
  .bind('account_status3', 'Some_Status_3')
  .execute()
