Serialize JSON like objects passed to `execute` as `key = 'val'` pairs?

await ctx.db.execute('INSERT INTO user SET ?', [{ email: body.email, password: hash }])

This throws an error, as JSON like objects are simply serialized as a JSON string. Is there a way to serialize as key = 'val' pairs? If not, what is the reason why?

https://github.com/mysqljs/mysql serializes JSON like objects like:

Objects are turned into key = ‘val’ pairs for each enumerable property on the object. If the property’s value is a function, it is skipped; if the property’s value is an object, toString() is called on it and the returned value is used.

If not, what is the reason why?

No. “Execute” is for prepared statements, where code (“sql”) and data separated. key = 'val' part is breaking this - it requires modification of sql query you want to execute.

If you really need this, you can use .query(). With prepared statement each placeholder must map 1:1 to input parameter (In case of mysql JSON type it can be an object, but it’ll be serialized to string before transmitting - this is what you observe. We could add some warning if types are inherently incompatible (and we know in advance, which is usually but not always possible - we get this metadata from PREPARE)

Found issue https://github.com/sidorares/node-mysql2/issues/553 which is more specific to my question, so I’ll continue there.
