types, such as lists and dictionaries, cannot be keys because they are not hashed.All immutable types are hashed, so they can all be used as keys to the dictionary. To illustrate: numbers with equal values represent the same key, that is, the hash values for integer number 1 and floating point 1.0 are the same, and they are the same key.At the same time, there are some mutable objects (rarely) that are has

If a parameter is used in the WHERE clause, a full table scan is performed. Because SQL parses local variables only at runtime, the optimizer cannot postpone the selection of the access plan to runtime; it must be selected at compilation. However, if an access plan is created during compilation, the value of the varia
