Bulk Update in CAP (Node.js)

[KM11]

Hi CAP Experts

david.kunz2 gregorwolf mariusobert thomas.jung mioyasutake

I am trying to do a bulk update on an entity but getting an error "invalid column name: 0_ID".

The entity has only one key field CUID from sap/cds/common.

Update statement: "await db.run(UPDATE(Rates).with(arrUpdate))".

arrUpdate is an array of json objects. In all the json objects I am passing the ID along with other fields to be updated.

Expected behaviour: above query shall update all fields where respective ID exists in the DB table. Or do I need to update each record in a loop?

PS: It is not an update on a deep composition.

Thanks Kanika

Can you do a console.log on Rates and arrUpdate?

I bet you have some weird situation where your Rates object or the array have incorrect information.

Hi martin.stenzig3

Below are the console.log output of both arrUpdate and Rates(entity).

Also, is my update statement correct as per the syntax?

definition of Rates: const { Rates } = cds.entities(<namespace>);

arrUpdate(SimpleArray):

"console.log(arrUpdate)"
