sequelize.query（）引发未处理的拒绝

Question

我得到

error: Unhandled Rejection at: Promise {"_bitField":18087936,"_fulfillmentHandler0":{}}

在

var Query = [
          `SELECT COUNT(*) FROM ${table1};`,
          `SELECT COUNT(*) FROM ${table2};`
        ];
sequelize.query(Query).then(result => {
          console.log(result);
        });

什么原因导致此错误？

Answer 1

在处理承诺时始终使用catch块。

      `sequelize.query(Query).then(result => {
      console.log(result);
    }).catch(error =>  console.log(error));`

Answer 2

在创建连接时必须设置multipleStatements = true：

new Sequelize(..., {
  dialectOptions: {
    multipleStatements: true
  }
})
