identifying sql error

i'm trying to add mysql column of type SET.

        $this->table('project', ['id' => 'prj_id'])
            ->addColumn('prj_status', 'set', ['default'=>'active'])
            ->create();

yet this gives SQL error, and i'm unable to see anywhere what the assembed sql statement was, even with -vvv commandline option and mysql server general log.

Exception trace:

Suggestions:

• a) print the assembled sql when exception is thrown
• b) print the assembed sql when high verbosity is enabled

ps: i added echo $sql to vendor/robmorgan/phinx/src/Phinx/Db/Adapter/MysqlAdapter.php:305, just before $this->execute($sql); and the broken sql was:

CREATE TABLE `project` (
 `prj_id` INT(11) NOT NULL AUTO_INCREMENT,
 `prj_status` SET NOT NULL DEFAULT 'active', PRIMARY KEY (`prj_id`)
) ENGINE = MyISAM CHARACTER SET utf8 COLLATE utf8_general_ci;

ps2: the correct field definition would be:

->addColumn('prj_status', 'set', ['default' => 'active', 'values' => ['active', 'archived']])

Start with the SQL assembly in src/Phinx/Db/Adapter/MysqlAdapter.php around line 305, then follow execution through PdoAdapter.php:338. Reproduce the migration using the SET column example and verify that the assembled SQL is available when the database reports an error or verbosity is enabled.
