renderDropTable method
Implementation
@override
List<String> renderDropTable(String tableName, {bool ifExists = false}) {
final drop = ifExists ? 'DROP TABLE IF EXISTS' : 'DROP TABLE';
// Separate statements: the MySQL wire protocol rejects several
// semicolon-joined statements in a single execute().
return [
'SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0',
'$drop `$tableName`',
'SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS',
];
}
