I want to increase the customer firstname max length so I have updated the length of that column using my custom module dbschema.xml.
After updating the length, I can see the updated length in PHPMyAdmin but when I check the column length using the below query, it’s showing the older length
select column_name, data_type, character_maximum_length from information_schema.columns where table_name = 'customer_entity';
Can anyone please confirm whether this is the right way to increase the field length?
