If you perform a cast, then the value can be changed ([playground](https://www.typescriptlang.org/play?#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-A9CIvAAiACiqwYiBq+g7SRxHfADlQAHJhAA5AMdoIqADy3zIu0EkH4CuOqEcClc0h5TiLOlGWH0KAQiBhwiulYkxeiIgMHBx3RYbC43CCJSAA)), although it looks a little strange.

@fgatti675 I was thinking of a simpler option where the map works similarly to an array. Since the key is always a string, you can simply specify the value property...

@fgatti675 Yes you are right. This is an example where the key is an auto-generated identifier (string), and the value is any property. The problem is that validation only works...

It would be nice if you could pass arguments to the FROM clause
