plugin to alter table change column name and update schema
It's possible to make modifications to schemas using the loadSchema() and saveSchema() functions. Specifically, if you want to rename a field, you could do something like this:
$schema = loadSchema('table_name'); $schema['field_key']['label'] = 'New Label'; saveSchema('table_name', $schema);
You'd just need to substitute your own table/field values.
