为什么在原始查询更新中未定义续集元数据？

Question

I am using sequelize to run a raw MSSQL update query. The documentation for raw update queries states that the message for number of rows updated will be contained in the metadata. In the following function both results and metadata are undefined on update statements. It works perfectly fine if I use a normal select statement.

Documentation

The section in reference is the very first example.

Could someone help me understand what I am doing incorrectly?

var query = 'UPDATE contacts SET aolid = 1 WHERE contactid =  804748'  

connection.query(query).spread(([results, metadata]) => {
        console.log(metadata)  // will log undefined
        console.log(results) // will log undefined
      })

Answer 1

Either use

.then(([results, metadata]) =>

or

.spread((results, metadata) =>

but .spread(([results, metadata]) => will not work. See spread() .
