Issue with update_all

Hi,

I am facing problem while the executing below query

ModelName.update_all(["field_id = ?, updated_at = ?", 345, Time.now], ["field_id = 1"], :order => "id", :limit => 1)

Here is the exception I am getting

ActiveRecord::StatementInvalid: Mysql2::Error: This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery': ModelName.update_all(["field_id = ?, updated_at = ?", 345, Time.now], ["file_id = 0 "], :order => "id", :limit => 1)

This query is working fine before I used seamless_database_pool gem.

Please let me know if there is any solution.

Thanks

Can you capture the SQL generated with and without the gem installed from your development logs.
