Deleting a non-existing identity in DynamoDB Golang-CodePudding

I am having a golang project where I am using dynamoDB as my backend database. I wanted to return the error when we are trying to Delete a non-existing entity. But the DynamoDB.DeleteItem does not return an error on that thing. Please help me with that.

CodePudding user response：

You can actually do it using the response you will get from DeleteItem method in dynamoDB.

Ex:

resp, err := dynamoDB.DeleteItem(input)
    if resp.ConsumedCapacity != nil {
        \\entity not found error
    }

CodePudding user response：

Actually, the first struct returned by the DeleteItem function is a DeleteItemOutput

There's a comment that addresses how this object would be present

This map appears in the response only if ReturnValues was specified as ALL_OLD in the request.

You can adjust your logic accordingly and it might solve your problem
