Labels
Applies to ❌ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
In imperative languages, labels are essential with simpler cases of loops (e.g. the LOOP statement), with nested loops, or if you must, when using the GOTO statement.
Using jOOQ, you can label any org.jooq.Statement by using DSL.label():
-- PL/SQL <<label>> BEGIN NULL; END;
// All dialects
Label label = label("label");
label.label(begin())
That's a lot of labels.
The main usages of these labels will be discussed in the following sections about, EXIT, and CONTINUE
