node mysql2 can't access update results - mysql

Question

I'm doing a simple UPDATE with mysql2 :
UPDATE table1
SET table1.value1 = ?, table1.value2 = ?
WHERE user_id = (
SELECT user_id
FROM user
WHERE company_id = ?
)
table1 is related to the user table by user_id, but I only have the company_id so I do a subquery (probably should be a join, but thats another discussion):
const [results, buff] = await connection.execute(query, values);
return results
However, when accessing the results to make sure there are no errors and that only a single row is updated, results returns:
console.log
ResultSetHeader {
fieldCount: 0,
affectedRows: 1,
insertId: 0,
info: 'Rows matched: 1 Changed: 0 Warnings: 0',
serverStatus: 2,
warningStatus: 0,
changedRows: 0
}
But I can't access the values. If I try results.affectedRows I get
Property 'affectedRows' does not exist on type 'RowDataPacket[] | RowDataPacket[][] | OkPacket | OkPacket[]'.
The only way to make it work is to do results['affectedRows']. Any suggestions?

Answer 1

So I forgot to mention that this is a typescript error, and I was able to fix it by doing:
const [results, buff] = await connection.execute(query, values);
const json: any = results;
return json.affectedRows //or whatever property I want
This also works:
const [results, buff] = await connection.execute(query, values);
return json as any; //then in the calling fuction access the properties I want
