如何在MySql中使用sequelize运行多个原始查询？

我试图运行一个脚本，以在通过sequelize同步之前从数据库中删除所有表 sequelize.sync({ force: true });

当我从控制台运行该脚本时，它没有任何问题，当我尝试从自己的node.js应用程序运行该脚本时，便会出现问题。MySql返回一个解析错误。

node.js

var dropAllTables = [
    'SET FOREIGN_KEY_CHECKS = 0;',
    'SET GROUP_CONCAT_MAX_LEN = 32768;',
    'SET @tables = NULL;',
    "SELECT GROUP_CONCAT('`', table_name, '`') INTO @tables FROM information_schema.tables WHERE table_schema = (SELECT DATABASE());",
    "SET @tables = CONCAT('DROP TABLE IF EXISTS ', @tables);",
    "SELECT IFNULL(@tables, 'SELECT 1') INTO @tables;",
    'PREPARE stmt FROM @tables;',
    'EXECUTE stmt;',
    'DEALLOCATE PREPARE stmt;',
    'SET FOREIGN_KEY_CHECKS = 1;',
    "SET GLOBAL sql_mode = 'STRICT_ALL_TABLES';"
].join(' ');

sequelize.query(dropAllTables, {
    raw: true
}).then(function() {
    return sequelize.sync({ force: true });
}).then(function() {
    console.log('Database recreated!');
    callback();
}, function(err) {
    throw err;
});

错误

{ [Error: ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET GROUP_CONCAT_MAX_LEN = 32768; SET @tables = NULL; SELECT GROUP_CONCAT('`', t' at line 1] code: 'ER_PARSE_ERROR', errno: 1064, sqlState: '42000', index: 0, sql: 'SET FOREIGN_KEY_CHECKS = 0; SET GROUP_CONCAT_MAX_LEN = 32768; SET @tables = NULL; SELECT GROUP_CONCAT(\'`\', table_name, \'`\') INTO @tables FROM information_schema.tables WHERE table_schema = (SELECT DATABASE()); SET @tables = CONCAT(\'DROP TABLE IF EXISTS \', @tables); SELECT IFNULL(@tables, \'SELECT 1\') INTO @tables; PREPARE stmt FROM @tables; EXECUTE stmt; DEALLOCATE PREPARE stmt; SET FOREIGN_KEY_CHECKS = 1; SET GLOBAL sql_mode = \'STRICT_ALL_TABLES\';' }

我在Google或sequelize docs页面中都找不到关于带有sequelize的多个原始查询的任何信息（我在寻找该query方法的特定参数）。

编辑：

我从SO克隆中找到了这个线程，那里的人们似乎也遇到了同样的问题，但我不知道解决方案是什么。
