const { AliasedExpression } = kysely;
A type that holds an expression and an alias for it.
AliasedExpression<T, A> can be used in places where, in addition to the value type T, you
also need a name A for that value. For example anything you can pass into the select method
needs to implement an AliasedExpression<T, A>. A becomes the name of the selected expression
in the result and T becomes its type.

class SomeAliasedExpression<T, A extends string> implements AliasedExpression<T, A> {
#expression: Expression<T>
#alias: A

this.#alias = alias
}
get expression(): Expression<T> {
return this.#expression
}
get alias(): A {
return this.#alias
}
toOperationNode(): AliasNode {
return AliasNode.create(this.#expression.toOperationNode(), IdentifierNode.create(this.#alias))
}
