php - How to check if db execute sql fails? -


i use console command in yii2 framework , want import db schema file via execute() method:

public function actionreset() {     $schemaspath = yii::getalias('@common') . directory_separator . 'data' . directory_separator;     $schemafile = $schemaspath . 'schema.sql';     try {         $command = yii::$app->db->createcommand(file_get_contents($schemafile));         $command->execute();          console::output('schema imported.');         return self::exit_code_normal;     } catch (\exception $e) {         console::error($e->getmessage());     }     return self::exit_code_error; }

documentation says:

this method should used executing non-query sql statement, such insert, delete, update sqls. no result set returned.

run as:

$ ./yii db/reset

produce no error/exceptions.

run as:

$ mysql -u{user} -p -hlocalhost -d{base} < schema.sql

produce:

error 1064 (42000) @ line 241: have error in sql syntax; check manual corresponds mariadb server version right syntax use near 'json default null ) engine=innodb default charset=utf8 collate=utf8_unicode_ci' @ line 4

because mariadb 10.1 don't support json data type. so, how check if queries/commands $schemafile success? trying find yii::$app->db->getlasterror() - no result. hm, ideas?

i found solution here: https://stackoverflow.com/a/23258691/1829368, it's:

try {     $command = yii::$app->db->createcommand(file_get_contents($schemafile));     $command->execute();      { } while ($command->pdostatement->nextrowset());      console::output('schema imported.');     return self::exit_code_normal; } catch (\exception $e) {     console::error($e->getmessage()); }

a do-while loop nextrowset() trigger \pdoexception when first db query fails.
