Detailed Description

This class represents an SQL/PSM label. Can refer to the identifier used with the "label_name:" construct which may precede some SQL/PSM statements, or to an implicit implementation-dependent identifier which the parser inserts before a high-level flow control statement such as IF/WHILE/REPEAT/LOOP, when such statement is rewritten into a combination of low-level jump/jump_if instructions and labels.
