◆ gate_null()

UUID provsql.gate_null ( )

Return the UUID of the value gate standing for the NULL value.

A constant, like gate_zero() and gate_one(); the gate itself is a value gate that displays as NULL. Its UUID is what tells it apart from the value gate of the string 'NULL'; the seed 'null' is no 'value' || TEXT, so no actual value shares it.
