sequelize.query（）抛出未处理的拒绝

Question

I get a

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

at

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

what is causing this error?

Answer 1

Always use catch block when handling promises.

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

Answer 2

Must set multipleStatements = true when creating a connection:

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