Unique bank account numbers
===========================

It can be desirable to be able to rely on a bank account number identifying
exactly one partner. This module allows you to enforce this, so that an
account number is unique in the system.

Installation
============

During installation, the module checks if your bank account numbers are
unique already. If this is not the case, you won't be able to install the
module until duplicates are fixed.

The error message only shows the first few duplicates, in order to find all
of them, use the following statement::

    with res_partner_bank_sanitized as (
        select
            id, acc_number,
            regexp_replace(acc_number, '\W+', '', 'g') acc_number_sanitized
        from res_partner_bank
    ),
    res_partner_bank_sanitized_grouped as (
        select
            array_agg(id) ids, acc_number_sanitized, count(*) amount
        from res_partner_bank_sanitized group by acc_number_sanitized
    )
    select * from res_partner_bank_sanitized_grouped where amount > 1;
